Jefferson Lab is about to enter the next phase in making the 12 GeV Upgrade to the Continuous Electron Beam Accelerator Facility a reality. In mid-May the first of two extended shutdowns to CEBAF will get underway.
The focus so far has been on coordinating and integrating the huge effort that will begin on May 13.
To set the stage for the down, laboratory leadership and the team planning the work held two sessions of an All Staff Pre-Shutdown Meeting on May 3 and 4. The meeting agenda included an overview of the scope of work for the down and important safety information. A video of the meeting is available on Insight for individuals who missed the meeting.
While some maintenance will take place, this will be no routine CEBAF shutdown. Scheduled to run from May 13 through Nov. 11, the Six-Month Shutdown will bring together a team of contractors, temporary workers, and staff from across the lab including the Accelerator, Engineering, Physics and ESH&Q divisions, the 12 GeV Upgrade Project team, and personnel from the Facilities Management and Logistics group and the Project Management and Integrated Planning office. Several other JLab work centers will provide support as needed.
"Jefferson Lab hasn't undertaken a job this extensive, complex and dynamic since the original construction and installation of CEBAF. I suspect that in some ways integrating the Upgrade with all the other work that is taking place is even more complex and challenging," notes Lab Director Hugh Montgomery. "We will be removing, upgrading and re-installing existing components and systems and installing new.
"Planning for the work flow and needed resources, and the staffing and range of skills and training has already been a major effort," he adds.
A real challenge is that, at the end of this long and busy period, the machine needs to be reassembled, locked down and restarted for operation in a timely fashion to complete the final six months of the 6 GeV scientific program. The three experiments scheduled to run are G2P in Hall A, HDice in Hall B and the completion of Q-weak in Hall C.
Bringing CEBAF back online is scheduled to begin Oct. 20 and Accelerator Operations plans to have the accelerator up and running for experiment commissioning by Nov. 19.
At the end of this final run at 6 GeV, CEBAF will shut down for 12 months, May 2012 to May 2013 during that period the rest of the upgrades and accelerator installation work will be accomplished. Machine and experimental equipment commissioning will follow with the expectation to begin the 12 GeV scientific program in 2015.
The effort to plan, integrate, schedule and prioritize the work and allocate resources for the Six-Month Shutdown began in October 2010. Lab management appointed Fulvia Pilat, Accelerator Division deputy director, as the Six-Month Shutdown coordinator. She is leading a team of nearly 20, representing all parts of the laboratory that have scope of work planned during the down or key roles and functions.
The team has developed an integrated schedule with baseline goals and identified risks. There is a methodology to address organizational communications and solve problems, with the further goal of gathering and analyzing lessons learned in preparation for the 12-Month Shutdown.
The integrated field operations, headed up by Steve Suhring, will be modeled on accelerator operations practices during beam operations and shutdowns. During the down, Pilat will chair a daily 7:45 a.m. meeting in the Machine Control Center, Building 85, which will cover the work planned for the day and resolve any outstanding issues. That will be followed at 8 a.m. by a meeting to communicate and coordinate the daily activities, chaired by Suhring.
Team leaders will convene weekly at 1:30 p.m. on Wednesdays to monitor and review the baseline work schedule, and to handle resource management questions and resolve problems and fine tune the schedule.
Work scheduled during the shutdown runs the gamut from new civil construction work and planned maintenance to CEBAF infrastructure and utilities systems; extensive above- and below-ground tunnel work for the 12 GeV Upgrade (installing the first of the C100 cryomodules and extensive work on the arc magnets); construction on the Hall D complex; upgrades and installations to accelerator support systems including the low-conductivity water cooling systems and personnel safety system; infrastructure and utilities repair and maintenance; and installation work for the last 6 GeV experiments in Halls A, B and C.
Construction work on the new Technology and Engineering Development Facility will continue as the Superconducting Radiofrequency Institute continues processing, assembly and testing of the C100 cryomodules needed for the upgrade. Hall D solenoid coil testing will also continue in the Test Lab. The Free-Electron Laser plans to install a new ultra-violet wiggler magnet and to run a science program during this period.

Based on work done by Kevin Jordan, a senior engineer in the Free-Electron Laser Division, and his electrical engineering team, Jefferson Lab recently received an environmental excellence award from the Commonwealth of Virginia.
The Virginia Department of Environmental Quality presented the lab with a Governor's Environmental Excellence Gold Award for 2011 on April 6 in Lexington, VA.
The awards recognize the significant contributions of environmental and conservation leaders in three categories: environmental projects, environmental programs and land conservation. They are given to businesses and industrial facilities, not-for-profit organizations, government agencies and individuals. Award winners are chosen based on criteria including environmental benefit, stakeholder involvement, public outreach, transferability and innovativeness. Winners are recognized at the gold, silver and bronze levels.
In a news release, Gov. Bob McDonnell remarked, "We are very proud of the Virginians in these private, non-profit and government entities who have demonstrated the innovation and dedication to improve our environment and make the lives of their fellow Virginians better."
The challenge faced by the FEL team was the recovery and containment of sulfur hexafluoride, more commonly referred to as SF6, the most potent of the greenhouse gases in its negative effect on the atmosphere. SF6 is used at JLab to suppress arcing in high-voltage DC electron sources, and is widely used in the commercial power transmission industry in circuit breakers, gas-insulated substations and other switchgear to manage the high voltages carried between generating stations and customer load centers.
Before its impact to the environment was understood, the gas was vented into the atmosphere. But, early on, in an effort to save time and money, the FEL team designed and built a recovery system to capture and store the gas when the FEL high-voltage system was opened for maintenance. Once evidence was clear that SF6 has a greenhouse gas potential at least 20,000 times greater than carbon dioxide, efforts to capture and store it intensified.
Since 1998, the containment system has been continuously refined, and now includes a remote cesiator – a purification and dehydration component. As a result, the gas is not only safely captured, but it can be conserved and reused rather than being replaced by new product. It's estimated that the program has prevented the release of the equivalent of 900,000 tons of carbon dioxide since its implementation, and saved more than $1.5 million over the past 10 years.
The FEL's SF6 recovery system uses readily available hardware and a process that is inexpensive relative to commercially available recovery systems. Bringing accessible components and technologies together in a novel way, the group has devised a capability that has been shared with the Department of Energy's Fugitive Emissions Working Group and other DOE facilities.
"Transferring the gas was the dominating task in the process," Jordan notes. "Our first system took four hours, and we've got that down to one-half hour."
The effort also received a "noteworthy practice" commendation by the Department of Energy when it recently announced its annual pollution prevention and environmental sustainability awards. Additionally, the SF6 Fast Recovery System is directly contributing to DOE and JLab's shared site sustainability goals for reducing greenhouse gas emissions.

Harris Power & Equipment, based in Yorktown, Va., has been recognized as Jefferson Lab's Outstanding Small Business Subcontractor of the Year for 2010.
R. Dudley Harris, company president, and several Harris employees who regularly carry out contract work at Jefferson Lab, attended an awards ceremony at the laboratory on April 21. Harris accepted the award, saying, "Being chosen to receive this award means a lot to us. We appreciate this recognition and your business. Our workers earned this and they are very deserving of this recognition."
Department of Energy officials and senior Jefferson Lab management and procurement and facilities management staff gathered to commend Harris Power for being selected as the 2010 recipient.
Mike Dallas, Jefferson Lab's chief operating officer, said, "Small businesses are very important to the nation and to Jefferson Lab. Harris Power makes a significant contribution to the laboratory on a daily basis."
"This is a tough contract," remarked Rusty Sprouse, Facilities Management and Logistics director. "Harris Power is here day in, day out, weekends and at night – doing many types of jobs. We are very appreciative of your hard work and your ability to meet our needs."
Harris Power & Equipment, in business since 1972, primarily handles generator installations and all types of electrical installations, systems maintenance and repairs and various types of construction projects. It is licensed as a "Class A" electrical, general, plumbing and gas pipe fitting contractor in Virginia.
With a workforce averaging 30 people, the company was awarded its first Jefferson Lab contract in December 2002. Its total contract awards from the lab since then exceeds $4.7 million. Last year the company completed 648 work orders, inspected more than 400 electrical panels and performed preventative maintenance on all of the laboratory's generators.
In the past year, the company also has completed a number of very important projects for the JLab, according to Paul Powers, electrical systems and energy manager. "The company has taken on tasks that have been a tremendous benefit to the laboratory. Its workers have devised procedures to safely and efficiently carry out maintenance, repair and change-out work on a variety of JLab electrical systems. Their efforts have made our facilities and systems run more efficiently and dependably," Powers said.
"Harris Power arranges its JLab work schedule to accommodate our constantly changing scope and priorities. And the company's employees work hand-in-hand with us to improve safety. They make valuable suggestions on how to implement new requirements in a way that makes sense and is repeatable.
"From a quality standpoint, their work is top level. They don't take shortcuts. They come in early and stay late to support our normal work schedules so that their impact to our operations is invisible," Powers noted. "But while their work may be invisible to many, it is very much appreciated by those of us who know what they're doing."
The company installed the electrical distribution system in the Central Materials Storage Area. It included providing power to six buildings, a new fuel filling station and a new underground distribution system, according to Powers. "Harris' ability and willingness to put that job on the fast track enabled the Technology and Engineering Development Facility project to stay on schedule."
Harris Power workers delivered and operated emergency generators to JLab during the holidays in late December 2010 when power distribution equipment was damaged and electrical service was interrupted. Harris workers then set about repairing the damaged system so that regular power could resume.
The company replaced the high-voltage fuse holders in the 1500 kilovolt (kVA) substations across the laboratory, which greatly increased the reliability of those substations and enabled continued operation of the accelerator.
Harris Power workers repaired and modified the Hall C, 2,000 kVA transformer by adding an external switchboard. This allowed the Q-weak experiment to run without interruption.
The company also provided all of the temporary connections to the generators provided last summer to reroute the underground electrical distribution system to support the TEDF construction project. Harris provided all of the connections and pulled all of the wire, which required its staff to work throughout the weekend, so that campus buildings were ready for work on Monday morning.
"These were enormous and complex jobs. All of the work was done in a manner to guarantee the safety of the workers and JLab staff and visitors," Powers said.
"Competition for this award is keen," noted Danny Lloyd, the lab's small business program manager. "
Jefferson Lab subcontracts a broad range of services and Harris Power is one of several hundred small businesses that work with the laboratory. Using the lab's established criteria for this award, the award committee reviewed the nominations and made the winning selection.

As a young man, David Richards, thought he was headed for a career in mathematics. The Wallingford, England, native excelled in the subject throughout his schooling and headed off to Cambridge intent on that degree. But, working in an accounting office in the days when accounting was done with, as he puts it, "bits of paper and double-entry account keeping," disabused him of the notion of that application of math.
"It was," he noted, "very boring."
By the time he completed a bachelor's degree and beyond in math, he'd already determined that he was going to head in a different direction.
"I just knew I was not cut out to be a pure math type," he said.
Now JLab's deputy director of the Theory Center, Richards went on to earn a Ph.D. at Cambridge University. There, he worked on Perturbative Quantum Chromodynamics under James Stirling and Peter Landshoff. He then went to Southampton University for his postdoctoral work in particle theory, where he, in his words, "first dipped my toes in the water of lattice."
He first came to the United States in 1986 to work as a postdoc at Argonne National Lab in the High Energy Physics division. While there he met the woman who would become his wife.
"We were both the worst badminton players at the Oak Park YMCA," he said with a laugh.
Her pursuits were decidedly unscientific. A fashion major, she came from a family of artists and had worked at the Art Institute of Chicago.
They returned to the U.K. in 1988 for Richards' work as a postdoc in particle theory at the University of Edinburgh, a major center for lattice QCD work. With its own ICL supercomputer, the group at Edinburgh came in with some impressive results. The UKQCD national collaboration allowed the group to purchase another supercomputer, which Richards describes as "a big box that looked like a wardrobe."
In the early 1990s, Richards met Nathan Isgur, who would become JLab's chief scientist, when Richards organized a workshop at Edinburgh at which Isgur spoke. When Richards and his wife were considering a return to the U.S. in the late 1990s, he rang Isgur up and found that the lattice group was about to begin. Richards came to Jefferson Lab as a staff scientist and joint faculty member at Old Dominion University in 1999. He became a full-time staff scientist in 2002 and served as acting Theory Center leader from September 2009 through October 2010. He was appointed deputy director of the Theory Center in mid-October 2010.
"This is a big experimental lab, and a big theory lab," he noted. "Together, we have this amazing amalgam of theorists and experimentalists and an outstanding opportunity for the two to come together. Being at a lab like this, and having the opportunity to actually talk to and interact with the people who are doing the experiments, allows us all to see the whole picture."
Richards' current research focus is aimed at garnering a better understanding of so-called "excited states." These are subatomic particles that were once the familiar protons and neutrons, but now have additional energy. The experimental determination of their masses and properties is an important effort at Jefferson Lab, any particularly in Hall B. Richards and his colleagues use supercomputers at Oak Ridge National Lab, and the high-performance GPU-enabled (graphics processing unit) clusters at Jefferson Lab, to compute the masses and properties of these excited states from first principles, using lattice QCD. Comparing these calculations with experimental data provides crucial insights into the nature of matter, and how the masses of so-called hadronic matter, such as protons and neutrons, arise from QCD.
A particularly exciting recent calculation is that of the masses of so-called "exotic mesons," mesons that cannot be constructed from straightforward excitations of a quark and an antiquark, the fundamental building blocks of QCD. The search for such mesons is the aim of the GlueX experiment with CEBAF at 12 GeV. Richards and his colleagues predict that there will be exotic mesons at a mass that will be accessible to GlueX, underpinning the scientific imperative for the experiment.
Throughout his career, Richards has received numerous awards, including scholarships at Cambridge and an advanced Fellowship at Edinburgh. He serves on committees such as the Lattice QCD Executive Committee and was the co-organizer of Lattice 2008, the 26th International Symposium on Lattice Field Theory held in Williamsburg, and a panel convener for Forefront Questions in Nuclear Science and the Role of High Performance Computing, held in 2009 in Washington, D.C.
Richards and his family live in Williamsburg. He is an avid cyclist, shooting for 100 miles a week, although he confesses to being a "fair-weather rider" who achieves his goal only part of the year. His wife, who went on to earn an MBA, worked in marketing with large pharmaceutical companies after their return to the U.S., and their son is a high-school sophomore and basketball player.

Senior Engineer Kevin Jordan, Free-Electron Laser Division, spent his youth on the go - always tinkering and always pushing the limits. Seventeen broken bones and a burn on his hand from an adventure with exploding rocket fuel, attest to his inveterate Type-A spirit.
This self-described "cheesehead" from Wisconsin admits he was never a scholar, but an avid builder, outdoorsman and athlete instead. After finishing technical school with an associate degree, he immediately went into the then-hot telecomm industry of the 1970s, working with digital switches and equipment calibration and testing. A colleague landed a job at Fermilab and suggested that Jordan look into it, too.
"I had no idea what it was," he recalled with a laugh. "I didn't even know national labs existed or what they were."
He followed up and was offered and accepted a position in the power supply group at Fermilab. During daily swims, Jordan learned about the lab's history from, in his words, "a nice older guy" who happened to be Fermilab's deputy director, Ned Goldwasser. As a result of their daily conversations and Jordan's interests, he moved into Electrical Engineering support group and began night school at Illinois Institute of Technology to complete his BSEE. After a number of years, he became group leader for switchyard support, which encompassed 2.5 miles of beam transport lines from the main ring to three experimental areas.
In the spring of 1985, he traveled to Europe to indulge his passion for skiing, at a time, he points out, when it was cheaper to go to Switzerland than to Colorado. He fell in love with Europe and made a commitment to go back. That fall, he returned for a month with a backpack and a Eurorail pass. He had setup an interview at DESY in Germany and wound up with three different job offers. By the fall of that year, he was living there, working in SRF (superconducting radiofrequency) and having the time of his life. He worked 10- to 12-hour days and took many three-day weekends to ski the Alps. Jordan not only skis down mountains but climbs them as well, and conquered Mont Blanc, the highest mountain in the Alps, while he was in Germany.
In the summer of 1986, Christoph Leemann, Ron Sundelin and Jock Fugitt toured the European SRF labs, including DESY. Jordan met them and was lured back to the U.S. for the building of the Continuous Electron Beam Accelerator Facility.
He arrived at Jefferson Lab (then CEBAF) in May 1987, and worked as a technical associate in the SRF group. In 1990, he completed his bachelor's in Electrical Engineering and received his Professional Engineer certification in 1993. Three years later, he became the lead Electrical Engineer at the Free-Electron Laser where he and the EE team started developing a gas recovery system on the FEL injector gun.
The low-cost system saves the lab money and helps protect the environment by containing and recycling sulfur hexafluoride, or SF6, a potent greenhouse gas that is used to suppress arcing in high-voltage systems. The Virginia Department of Environmental Quality recently recognized the effort with a Governor's Environmental Excellence Gold Award for 2011. (See story titled "FEL Team Earns State Environmental Award for Gas Recovery System" for information about the award.)
In addition to his work on containing SF6, Jordan has been instrumental in a project with NASA scientist Mike Smith to find better ways to synthesize boron-nitride nanotubes, work he began in 2001. He currently holds three patents for carbon nanotube synthesis work and has an additional 10 patents that are pending.
This time next year, Jordan will be even busier than usual. He's chairing the program committee for the 2012 Beam Instrumentation Workshop (BIW12), the 15th biennial meeting dedicated to exploring the physics and engineering challenges of beam diagnostic and measurement techniques for charged particle accelerators.

Jefferson Lab shares its grounds with an array of wild creatures, and recent construction has disturbed the natural habitat of many. Likewise, some of these critters can be disruptive to lab operations and dangerous if confronted – especially when they choose to enter indoor workspaces or undermine structures.
For example, groundhogs dig holes in accelerator shielding. Occasionally, snakes are seen near buildings. Stinging insects and spiders can be present indoors and out.
The Environment, Safety, Health and Quality Division and the Facilities Management and Logistics Department urge everyone to take precautions when working in areas that mimic or overlap the natural habitat of native creatures especially when working on the Accelerator Site during the spring and summer when many of these creatures are most active.
These precautions include:
If you should come across any wildlife in circumstances that cause you concern, alert Mike Lewellen at ext. 7169 or email@example.com as soon as feasible and follow up by putting in a FM&L Work Request. Do not confront or corner wildlife – FM&L retains the services of a pest control company and can safely deal with your concern.
If you are stung or bitten, report to Occupational Medicine and then contact Lewellen to notify him of the location and conditions. Prompt medical care can help prevent infection and complications that could result in unnecessary pain and lost work time.
Likewise, native poison plants such as poison ivy and poison oak quickly grow in disturbed ground such as construction site. According to the Centers for Disease Control, poison ivy, poison oak and poison sumac release an oil, urushiol, when the leaf or other plant parts are bruised, damaged or burned. Skin exposure to urushiol in amounts equaling less than a grain of table salt can cause an allergic reaction, resulting in an itchy red rash with bumps or blisters in 80 to 90 percent of adults.
Although over-the-counter topical medications may relieve symptoms for most people, immediate medical attention may be required for severe reactions, particularly when exposed to the smoke from burning these poisonous plants (never burn these plants). When working in areas harboring poisonous plants, the CDC recommends avoiding the plants when possible, covering all exposed areas with clothing or barrier skin creams and thoroughly cleaning items that may have come into contact with poisonous plants. For more information, including pictures of the plants, visit the CDC's website at: http://www.cdc.gov/niosh/topics/plants/
If you should come across poison ivy or poison oak growing in areas where it could come in contact with people, submit a FM&L Work Request and it will be sprayed.
Virginia Notes Uptick in Lyme Disease Cases
Since 2000, Virginia has witnessed a steady increase in the number of Lyme disease cases. Most cases occur during the late spring and early summer with illness presentation in June, July and August. Common symptoms of Lyme disease include: fever, headache, fatigue, "bull's-eye" rash, muscle aches and stiff neck.
Lyme disease is preventable. Information about Lyme disease and how to reduce the risk of contracting it is available on the Centers for Disease Control and Prevention webpage, at: http://www.cdc.gov/ncidod/dvbid/lyme/index.htm . According to the CDC, adhering to the following practices can decrease the risk of contracting this infection:
The Virginia Department of Health also provides information on preventing tick bites and tick-borne illness at: http://www.vdh.virginia.gov/environmental-epidemiology/tick-borne-disease-prevention-and-control/
An informational brochure provided by the Virginia Cooperative Extension and Virginia Tech is available at: http://www.tidewateratc.com/tatc/education/lyme_disease.pdf.
Eighty percent of adults can expect to have at least one episode of severe back pain in their lives, according to Dr. W. Smith "Smitty" Chandler, JLab's Occupational Medicine director. For most people, the episode will be of short duration, but for a few it can become a long-term or chronic problem.
But, it doesn't have to be this way. A large portion of work place back pain is preventable and is caused or aggravated by inadequate planning, not requesting an ergonomics consultation when appropriate and not thinking about and using good technique before starting to lift or move an object, Dr. Chandler explains.
The Occupational Medicine staff is available to advise individuals and groups across the lab, regarding the ergonomic lifting and moving of equipment, tools and materials. They can provide ergonomic consultations for Jefferson Lab staff, users and subcontractors in industrial and office settings, and conduct about 50 each year. An industrial consultation can help workers ensure that they are setting up and using equipment in an ergonomically safe manner, and help them determine how to plan and carry out safe moves or lifts of objects in their work areas.
In addition, Occupational Medicine has developed an educational and informational 30-minute DVD titled "Safe Lifting" that may be loaned out for individual and group viewing. "Watching it is a good place to start," Dr. Chandler suggests.
In the video, he discusses many of the causes and predictors of back pain, and explains "torque" or the physics behind lifting and why this can cause back pain. He then addresses the process a worker should follow when planning work that involves lifting or moving heavy or unwieldy objects and the techniques to use to prevent back injury and pain.
Dr. Chandler's most important advice, "Think about the lift before you do it. Just before starting the lift, tighten your abs," he says. "This will stabilize your back and makes it more difficult to hurt your back."
He encourages individuals with a history of back problems to talk to him, be extra mindful of their body and work activities, be cautious in their work motions, and to habituate proper lifting technique and cautious work behaviors so they do it automatically. "If you feel irregular, let us know," he adds.
Understanding a little basic physic and following a few straightforward steps can prevent nearly all back strain and back injuries at work and at home, Dr. Chandler notes.
For more information about scheduling an ergonomics consultation or to sign out the Safe Lifting DVD, contact Johnie Banks, Occupational Medicine, ext 7539 or email firstname.lastname@example.org .
Tips to Prevent Back Pain
Proper Lifting Steps
Six outstanding high school students have been selected to participate in the lab's High School Summer Honors Program, which will be held at the lab from June 20 through July 29. These students have a strong academic record and are excited to have the opportunity to dive in and learn about the lab's science and technology, according to Brita Hampton, Science Education administrator. The students are currently in the 10th and 11th grades and have expressed interest in pursuing scientific and technical careers.
Mentorship is a critical part of the learning experience for each high school student. Lab scientists, engineers and other technical managers who are interested in serving as a mentor to high-achieving high school students and have a project, or number of projects, to be accomplished this summer, are asked to send a description of the work to be assigned to Hampton, at: email@example.com . Email or call her at ext. 7633 if you have questions. She needs your ideas or proposals by June 1.
The students will be required to develop a poster about their project and present it during a poster session on the last day of their program.
Thousands of Virginia students are expected to flock to Jefferson Lab's Science Education website just as they have done each spring for the past several years as they prepare for the Virginia Standards of Learning tests.
Jefferson Lab recently received the 2010 SOL questions and responses from the Virginia Department of Education and has added them to the SOL archive on Jefferson Lab's website. New test categories added this year include (alphabetically) Algebra 1, Algebra II, Geometry, Math 8, Math 7, Math 6, Math 5, Math 4, Math 3, Science 5, and Science 3.
"The most frequently accessed pages on the website include the Virginia Standards of Learning Science, Math and Technology Practice Tests and our 'Who Wants to Win $1 Million?' math and science quiz," says Steve Gagnon, Jefferson Lab Science Education technician and webmaster. (No money is involved.)
The Jefferson Lab education website includes questions from the recently released 2010 Virginia SOL tests, as well as test questions and answers going back to 2000.
"The SOL practice tests are a great resource for students, teachers, parents, or anyone interested in the information," Gagnon adds.
The website is set up so a person can request 5, 10, 20, or 40 random multiple-choice questions from a single category. Or if desired, the site allows teachers and students to bring up non-random sets of questions. If a teacher wants a class to review a series of specific subcategories, the teacher can have the students go to the website's SOL index page and make an assigned series of selections from the "options" offered. Then all of the students will go through the same fixed set of questions.
"This feature is very useful for classroom settings," Gagnon notes.
The interactive design of the website lets users select and submit their answer. They are immediately told if their response is right or wrong. Whether a correct or incorrect response is given, the answer page repeats the question and provides the correct answer.
"Use of this review tool climbs significantly as preparation for the annual testing period gets underway," Gagnon notes. "Use usually peaks in May with daily page hits running into the several millions."
While a significant number of students from across Virginia use these review tools to prepare for SOL tests, teachers and students from a number of other states also use these web-based resources to review for annual academic tests.

Dr. William Bradford Tippens
In 2000, he joined the Nuclear Physics Division in what was then the Office of High Energy and Nuclear Physics, where he assumed the position of program manager for the Medium Energy Program.
Among his many accomplishments were the management of the 6 GeV research program and the developing 12 GeV program at Jefferson Lab, initiation of the program to measure the spin components of the proton at Brookhaven National Laboratory, and support of other important efforts including a Drell-Yan experiment and a neutrino oscillation experiment at Fermi National Accelerator Laboratory, atom trapping development aimed towards an atomic electric dipole moment measurement, the physics program with the BLAST detector at the Massachusetts Institute of Technology Bates facility, and experiments at several European laboratories.
Within the DOE, he took on a number of additional responsibilities, including management of the Nuclear Physics Outstanding Junior Investigator program, serving as the point-of-contact for education matters for Nuclear Physics, and taking part in the early efforts to modernize electronic workflow within the Office of Science.
Tippens made his home near Columbia, Maryland. He is survived by his wife, Tabitha, and three sons, Jonathan, Nathaniel, and Daniel.
