2014 JSA Thesis Prize Nominations Accepted
The Users Group Board of Directors is now accepting nominations for the 2014 JSA Thesis Prize for the best Jefferson Lab-related thesis. The prize is supported by the JSA Initiatives Fund Program. A complete package requires a nomination letter by a senior scientist giving the name and institution of the person being nominated and the names of three people who will send letters of recommendation, along with a copy of the thesis. All materials must be submitted electronically. The three letters of recommendation must be sent before the deadline. Theses completed during the calendar year 2014 are eligible, as well as theses completed during the last quarter of 2013 (if they haven't been submitted before). All materials must be sent by email to Lorelei Chopard by the nomination deadline of March 2. If you have any questions about the prize, contact John Arrington. See the full announcement for details.

JSA Accepting Applications for 2015-16 Graduate Fellowships
Jefferson Science Associates is currently accepting applications for graduate fellowships at Jefferson Lab for the 2015-16 academic year. The JSA/JLab Graduate Fellowship Program is supported by the JSA Initiatives Fund. FY2015 funds are available for up to seven fellowship awards. Application packages should be submitted via email to with the subject line "JSA Graduate Fellowships" by Feb. 20. See the full announcement.

JSA Accepting Applications for 2015-16 Sabbatical Leave Support Program
Jefferson Science Associates is currently accepting applications for the JSA/JLab Sabbatical Leave Support Program for academic year 2015-16 at Jefferson Lab. The JSA/JLab Sabbatical Leave Support Program is supported by the JSA Initiatives Fund. Materials should be submitted via email to with the subject line "JSA Sabbatical Support" by March 2. See the full announcement.

Center for Theoretical and Computational Physics

A new Theory Center paper proposes a new “locally smeared operator product expansion” (sOPE), in which non-local operators are decomposed in terms of a basis of smeared local operators. The sOPE formally connects nonperturbative matrix elements, which can be determined numerically using lattice field theory, to non-local operators in the continuum. These nonperturbative matrix elements do not suffer from power-divergent mixing on the lattice, which significantly complicates calculations of quantities such as the moments of parton distribution functions, provided the smearing scale is kept fixed in the continuum limit.

Environment, Safety, Health & Quality

Air Bag Safety
Air bags on vehicles can be live savers,  but they should only be used as supplemental restraint systems. The primary means of protecting yourself and your passengers in the event of a collision is by the use of the seat belt and shoulder strap.

Air bags increase the chances of surviving a vehicle crash, but, like many tools in our life, they have to be used correctly to obtain full benefits. There have been cases where people have sat too close to the air bag and have been killed or seriously injured by its explosive deployment. With the advent of side air bags, people who deliberately position themselves in the corner to sleep or from overcrowding are in danger. Passengers also should not sit back and place their feet on the air bag panel on the dashboard. Sitting with the feet up does not place one's body in the proper position for the full benefit from the seat belt/shoulder strap. Finally, elderly and children have specific "where to ride" conditions in some vehicles. One needs to read the owners manual to follow your particular vehicle’s requirement for where and how the elderly or children should be positioned.

When used correctly, seat belts and air bags do save lives.

Computing and Networking Infrastructure

Annual Computer User Account Audit Begins Soon
On Monday, Feb. 16, the IT Division will begin the annual computer user account audit. All supervisors and sponsors of employees/users with computer accounts at Jefferson Lab are required to review and re-authorize accounts. Supervisors and sponsors must complete the audit by close of business Monday, March 16. This audit is a critical part of maintaining an appropriate level of cyber security at Jefferson Lab. If you need assistance during the audit, contact Chris Williamson, x6245, or Jessica A. Perry, x7262.

Jefferson Lab Mailing List Problem Resolved
Since around noon on Monday, Feb. 2, messages sent to all Mailman mailing lists (such as all_staff, all_jlab_accounts, CUGA, etc.) were being blocked. However, the problem was fixed this morning. All messages that were blocked were delivered after 10:30 a.m. today. If you have any questions or concerns regarding this issue, contact the IT Division HelpDesk, x7155.


Graduate Student Research Grants Available
The Office of Science Graduate Student Research (SCGSR) program is now accepting applications for its 2015 solicitation. The SCGSR program provides supplemental awards to outstanding U.S. graduate students to pursue part of their graduate thesis research at a DOE laboratory in areas that address scientific challenges central to the Office of Science mission. The research opportunity is expected to advance the graduate students’ overall doctoral thesis while providing access to the expertise, resources and capabilities available at the DOE laboratories. The 2014 program solicitation resulted in awards to 65 graduate students from 50 different universities to conduct thesis research at 15 DOE national laboratories - three students are at Jefferson Lab. Applications are due April 14. The SCGSR website has specific details. If you have any questions about the program, contact Jan Tyler.

Jefferson Lab All-Hands Meeting Set for Thursday, Feb. 5
Lab Director Hugh Montgomery will conduct all-hands meetings on Thursday in the CEBAF Center auditorium for an update on safety, CEBAF commissioning activities and 12 GeV Upgrade status, lab initiatives, the budget, the NSAC Long Range Plan, the Electron-Ion Collider and other items. There will be two sessions - one at 9:30 a.m. and the other at 11 a.m. See the full announcement for suggested attendance schedule.

Tornado Warning Siren Test Set for Friday, Feb. 6
Jefferson Lab's tornado warning siren will undergo its monthly operational test at 10:30 a.m. on Friday, Feb. 6. Don't respond to the siren; this is a test of the siren system and not a personnel response exercise. Individuals planning to be in the Central Materials Storage Area (where the siren is located) while the test is taking place must have with them and wear two layers of hearing protection.

Join The Accelerators Musical Ensemble
The JAG Music Club has formed a musical entertainment ensemble. Musicians and vocalists of any level, genre and instrument are invited to participate. Practice sessions are held on Thursdays in the CEBAF Center auditorium, 4-6:30 p.m. For more information or to join, contact Sammy Mancuso.

Break Out the Bat and Glove for Jefferson Lab Co-Ed Softball!
The Jefferson Lab Co-Ed Softball Team is preparing to begin the spring season. The team plays in the York County Co-Ed Industrial League on Friday nights. The league maintains a family friendly atmosphere at its parks. Team members will need to bring their own glove, a Jefferson Lab jersey and an eagerness to play. If you'd like more information or to join the team, email Philip Stanley as soon as possible.

Jefferson Lab Dog Training Club 2015 Classes Scheduled
Is your New Year's Resolution to reduce tension (at least in your dog's leash)? Come join the Jefferson Lab Dog Training Club for their kick-off meeting for the new year! The meeting will be held in the lobby of the Support Service Center on Monday, Feb. 9 at 7 p.m. Rules for dog club participation will be reviewed, so no dogs at this first meeting. Classes for the 2015 Canine Good Citizen/Therapy Dog International session will begin on the following Tuesday, Feb. 17. See the full announcement for more details and dog club contacts.
