Vote for Users Group Board of Directors
The ballot for the election of new members of the Jefferson Lab Users Group Board of Directors (UGBoD) is now available.

Free-Electron Laser

The FEL team has started in procurement activities funded by the Commonwealth of Virginia for capital improvements to the FEL injector and linac. Other efforts are mostly on hold, as most staff has been transferred to organizations with funding.


The Installation group has made significant progress installing girders and magnets in the transport channel recombiner. The Bcom-style magnets (multipass bending dipoles with one vacuum chamber) have been installed in the 1st recombiner,1st spreader and 2nd spreader. Six of the 25 quad girders that carry the beam from the end of the north linac to the Hall D tagger area have been installed. These girders are installed on stands with just a few inches of clearance from the tunnel floor.

Additionally, the installation folks have been working in the beam switchyard. The BSY girder and dipole removal for upgrade work has been completed. Pedestal grouting has been carried out throughout the machine. Low-conductivity water work is almost complete in the 1st recombiner, 1st spreader and has begun in the 2nd recombiner.

The Vacuum group completed warm region girder work in the linacs to support cryomodule commissioning. The group is also continuing installation of beamline pipe in Hall A. Additionally, the group is cleaning and leak checking vacuum chambers for various septa magnets. Work is almost complete on the rebuilding of the quadrupole girders. Finally, the Vacuum group supplied a Roots blower to support the Central Helium Liquefier and is repairing a broken blower for the cryo group.

Environment, Safety, Health and Quality

Roadway Worker Safety
With the spring season, we have all noted the increase in work-zone signs and orange barrels along many roads, including in front of JLab. The signs are there for a reason. Each year, several hundred road workers are killed by drivers. These fatalities can be prevented by drivers who take extra care to remain alert for workers and moving vehicles on roadways marked with orange road work signs and barriers. Be on the lookout for workers who may step into the roadway without realizing how close they are to the path of oncoming traffic. Minimize your distractions, such as cell phone use, while driving through these areas. Always remain vigilant, and let the workers make it home to their families.


Take Our Daughters and Sons to Work Day Is April 25
Take Our Daughters and Sons to Work Day is set for Thursday, April 25. JLab has no formal plans for the day. However, JLab parents/grandparents are welcome to bring their school-age children/grandkids (8-18 years of age) to work for all or any part of the day. Parents are responsible for their children while they are at the lab. For more information, see the full announcement.

U.S. Customs and Border Protection (CBP) Announces Automation of Form I-94 Arrival/Departure Record
U.S. Customs and Border Protection (CBP) will begin automation of the I-94 records on April 26 at selected airports, with complete implementation at all airports by May 30. Non-immigrants traveling to the U.S. by air or sea will no longer be required to fill out a paper I-94 form and will no longer have a paper record in their passport.
With the new CBP process, a CBP officer will electronically stamp the passport of each arriving non-immigrant traveler. The admission stamp will show the date of admission, class of admission, and the end date in the U.S. for the traveler. On arrival, travelers will also receive a flier alerting them to go to to view/retrieve admission record information.
Travelers needing a hard copy of the I-94 form to obtain a Social Security card, state driver’s license, complete an employer’s I-9 process or prove legal status to universities, etc. will be able to print their record immediately from a CBP website ( available at the end of April 2013. The electronic record should expedite the wait period to receive the above referenced documents.
Upon exiting the U.S., travelers will no longer have a paper I-94 form to surrender. CBP will record the departure electronically via manifest information provided by the carrier or by CBP. 
For more information and for answers to frequently asked questions, visit CBP’s Form I-94 webpages.
Sue Ewing, x7687, or Tara Wilkerson, x6119, are also available to assist with inquiries as needed.

Pothole Patching Work to Start April 25
Beginning Thursday, April 25, work will begin to repair a few potholes on JLab roadway surfaces. The subcontractor is scheduled to saw cut asphalt at three pothole locations, beginning before noon on April 25 (weather permitting). Disruption to traffic will be minimal. However, traffic will be reduced to one lane in each area during periods of repair work.

Potholes to be patched include:

  • Near CEBAF Center Circle (just east of the circle). The concrete walkway also is to be repaired;
  • Pothole in Rattley Road near Residence Facility entrance; and
  • Pothole in parking area near Building 19.

If you have any questions, call Suresh Chandra, x7248. For more details, visit the webpage.

Colloquium & Public Lecture: The Higgs Boson and Our Life
Fabiola Gianotti, a spokesperson for the ATLAS collaboration, will discuss the discovery of a new particle compatible with the Higgs boson. Physicists have hunted the particle for almost 50 years, and describe it as a crucial piece for humanity's understanding of fundamental physics and, thus, the structure and evolution of the universe. The talk will include a description of the instruments and challenges that allowed such an accomplishment, the meaning and relevance of the discovery, and the implications for day-by-day life. The colloquium will be held in the CEBAF Center auditorium on April 30 at 1 p.m.

Science Series Lecture: The Higgs Boson and Our Life
Fabiola Gianotti, an experimental physicist at CERN's Large Hadron Collider and spokesperson for a group of researchers who identified the Higgs boson, will present this last Science Series of the spring. On July 4, 2012, two groups running the ATLAS and CMS experiments at the LHC announced the discovery of a new particle compatible with the Higgs boson. The lecture will describe the instruments and challenges that made this accomplishment possible, the meaning and relevance of the discovery, and the implications for day-by-day life. The lecture is free, open to students and adults and will begin at 7 p.m. in the CEBAF Center auditorium. Seating is limited and available on a first-come, first-served basis.

JLab Records and Information Management Fact of the Week
A records schedule provides mandatory instructions on how long to keep records (retention) and when they can be destroyed and/or transferred to alternate storage facilities (disposition). They are also known as records disposition schedules, records retention schedules, and records control schedules. To keep it simple, JLab uses the terms "records schedules" or "schedules." Schedules identify which records are temporary (eligible for destruction after a specific time period) and which records are permanent (transferred to the National Archives and Records Administration after a specific time period). By following the instructions in the appropriate schedule, you can:

  • Destroy/recycle records that are no longer needed;
  • Retire inactive records to offsite storage; or
  • Transfer permanent records to the National Archives.

DOE Records Schedules can be found here.

RIM Trivia Question of the Week
In 1934, President Franklin D. Roosevelt established this agency from which the universally recognized concept of the lifecycle of records management would be born. The first correct response received at wins a Starbucks gift card! (Winner will be notified no later than 5 p.m. Friday following publication of Weekly Briefs. Limit one gift card win per person.)

Congratulations to Tim Nellis for his super-fast response to last week's question: The term that has come to mean network abuse via junk email and junk postings to message boards most likely originated from a skit during which a group of Vikings sing the following song in a cafe: "Spam, spam, spam, spam, spam, spam, spam, spam, lovely spam! Wonderful spam!" What is the name of the group that performed the skit? The answer was Monty Python.

American Red Cross Blood Drive Exceeds Goal
The April 16 American Red Cross Blood Drive was very successful! The Red Cross collected 52 units of whole blood and red cells using the Double Red process exceeding our goal of 36 units. JLab donors made a significant contribution to the American Red Cross. Occupational Medicine staff extends a sincere thank you to everyone that participated with this blood drive and congratulation for a job well done!
