12 GeV Upgrade

Installation of the CLAS12 spectrometer in Hall B is progressing well on all systems. As of last week, four of the six Forward Time-Of-Flight (FTOF-2) detector array panels were installed. Due to geometrical constraints arising from the installation of the Region 3 drift chambers, the final two FTOF-2 panels won’t be installed until later this summer. With the hazardous overhead work throughout the experimental hall, and with many people and different activities in a congested envelop, communication and coordination is paramount for the safety of personnel and equipment.

Records and Information Management Month Fact of the Week
Information is everywhere. It's on our desktop computers, network shared drives, web servers, mobile devices, cloud storage, and mobile storage. There are two types of electronic records of interest to records and information management (RIM). The first are structured records, which are contained and defined in relational databases behind applications such as Costpoint and Maximo. The second are unstructured records, which are electronic files found in a directory on a server, tablet, cellphone, or cloud drive in the form of Word documents, Powerpoint presentations, images, emails, etc. Unstructured records are the most unruly and hardest to wrap our arms around. To find out how to rein in your unstructured information, contact Kim Edwards at

RIM Trivia Question of the Week
According to a recent New York Times article, IBM estimates that by 2020, websites, smartphones and sensors on everything from roadways to appliances will generate 44 zettabytes of data. IDC forecasts that the number of connected devices will grow to 32 billion and comprise 10% of the world's data. An innovating trend that is contributing to this rise in data is the increase in the system of everyday objects connected to the internet and able to automatically record, report and receive data. This system of interconnected, data-collecting objects has a name - can you guess what it is?

All responses must be received via email by Kim Edwards by noon on Friday, April 8, when a random drawing will take place of all correct answers. One person will win a Starbucks gift card! (Winners will be notified via email no later than 5 p.m. Friday following publication. Limit one gift card win per person.)

Last week's correct answer was "Filing Clerk." Thanks to all who played and congratulations to DeLisa Stanfield for winning the Starbucks gift card for being randomly selected out of all correct answers.

Center for Theoretical and Computational Physics

new paper recounts a personal view of developments in hadron physics over the past 40 years. How properties of the proton such as its mass and spin, that seemed simply understood in terms of constituent quarks 40 years ago, are now seen to reflect the complexity of the femto-universe of quarks and gluons: a complexity that the next decade of experiments at Jefferson Lab aim, with on-going theoretical developments, to explain in terms of QCD.

Environment, Safety, Health and Quality

Strange Spring Sprouts
Some of the strangest but most important "sprouts" every spring are orange cones and barrels and long, concrete barriers along road construction sites. They protect  road workers from errant cars and trucks, and they protect the drivers from roadside hazards. This week is National Work Zone Awareness Week. Here are some tips to help you drive safely around work zones:

  • Expect the unexpected. Keep an eye out for workers and slow-moving equipment.
  • Follow the signs. Signs and flaggers will direct you through the work zone.
  • Never change lanes in the work zone.
  • Minimize distractions. Avoid changing radio stations and using phones.
  • Be patient. Crews are working to improve the safety and comfort of your travels.

You can find these and other work zone safety tips online.

Computing and Networking Infrastructure

IT Division Systems Maintenance Tuesday, April 19, 5-10 p.m.
The IT Division is planning a maintenance period from 5-10 p.m. on Tuesday, April 19. During this maintenance period, all MIS applications will be unavailable while patches are installed and the systems are rebooted. All MIS applications should be back up and available by 10 p.m. Also, all Common User Environment-managed web severs and login servers will be rebooted to finalize patch installations. A short incoming email outage will also occur while the email servers are updated. This email outage will be short and last no more than 15 minutes. All incoming email will be queued on remote servers and delivered when service is restored. Finally, Windows and Linux patches and Core CUE Software updates (Firefox, etc) will be released to all CUE desktops. Plan on rebooting your desktop to finalize patch installation no later than Friday, April 22. If you have any questions or concerns about this maintenance period, contact the IT Division Helpdesk at or x7155.


2016 Small Business Vendor Fair Set for April 14
All members of the Jefferson Lab community are invited to the 2016 Small Business Vendor Fair on Thursday, April 14, in CEBAF Center, 9 a.m.-1 p.m. Come and go as works best for your schedule. More than two dozen vendors will have displays and tables set up in the CEBAF Center lobby and in Conference Room F113. Check out the newest gadgets and wares. Pick up free samples, giveaways and information. Register for drawings. Free refreshments will be available. If you have any questions about this event, contact Jami Anthony, x7060.

Lab-wide Open House & General Cleanup Set for April 14-22
Jefferson Lab will hold a lab-wide spring cleanup April 14-22 (a Thursday through the following Friday) in advance of the April 30 Open House. The cleanup will involve all divisions and all employees. Special attention is requested to all areas – indoors and out – that will be traveled on or by, or be visible to the public during the April 30 Open House. For more information about the cleanup, see the all-staff memo.

Take Our Daughters and Sons to Work Day Is Thursday, April 28
The nation-wide Take Our Daughters and Sons to Work Day will be on Thursday, April 28. Jefferson Lab has no formal plans for the day. However, Jefferson Lab parents and grandparents are welcome to bring their school-age children/grandkids to work for all or any part of the day. School age is defined as 8-18 years of age, per the national Take Our Daughters and Sons To Work Day website. Adults are responsible for their children while they are at the lab. Children are not permitted in work areas that are restricted or have limited access due to technical or safety considerations. If you are planning to bring a child to the lab for the day, take a moment to review important safety reminders and get information about making the most of the day.

Education Seeks Projects for Summer Honors Interns; Send Ideas/Proposals in by May 2
Six to eight outstanding high school students will be selected to participate in the lab's 2016 High School Summer Honors Program, which will be held at the lab June 27- Aug. 5. The students are currently in the 10th and 11th grades and have expressed interest in pursuing scientific and technical careers. Lab scientists, engineers and other technical managers who are interested in serving as a mentor and have a project to be accomplished this summer are asked to send a description of the work to Brita Hampton, x7633, by May 2. 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. See more information about the program in the full announcement.

Research Assistantship Program Now Taking Nominations
Jefferson Lab is seeking candidates for the 2016-2017 Minority/Female Undergraduate Research Assistantship (MFURA) program. Through the MFURA program, a minority or female junior or senior level undergraduate student will work on a Jefferson Lab-related project at his or her university during the academic year. Students must be nominated by university professors with whom the students would conduct the research. Nominations will be accepted through May 2. For information on the eligibility requirements or to nominate a student, see the linked webpage. MFURA is funded by the JSA Initiatives Fund Program, a commitment from the JSA owners, SURA and PAE Applied Technologies.

JLab Weekly Briefs is an ongoing publication providing information on the status of safety, accelerator operations, experiments, free-electron laser, reviews, upcoming activities and special events. Deadline for submission is every Tuesday by 10 a.m. Submit new items to: Public Affairs or contact Kandice Carter at x7263.
