12 GeV Upgrade

Everybody involved with the Hall C portion of the 12 GeV Upgrade Project rejoiced when the Department of Energy concurred that the Hall C Key Performance Parameter (KPP) had been demonstrated several weeks ago. Achievement of this milestone marked the conclusion of years of R&D, design, construction, installation and testing for the Hall C upgrade. The accelerator had delivered high-energy electrons for this KPP run, during which experimenters worked feverishly to collect and analyze data and report the results. Thanks to the intense installation work of the previous several months, Hall C was ready for beam delivery as planned. Timely completion of this objective was possible only due to the coordinated efforts of work groups from across the laboratory. Attention has now turned to preparation of the final project documentation and closing-out the earned-value-management and financial aspects of the Hall C 12 GeV Project. This material, documenting full Hall C scope completion, will be presented at the review to be conducted by DOE's Office of Project Assessment on May 10-11. 


JSA Young Scientist Program Now Accepting Applications
The JSA Promising Young Scientist program is accepting applications for the 2017-2018 academic year. The program, which is funded by the JSA Initiatives Fund, will assist candidates to prepare for faculty interviews by traveling to a host institution to present a talk and participate in a mock interview. The candidates will also have an opportunity to teach a class session. The application deadline is on 5 p.m. on Friday May 12. For more information, see the full announcement.

Center for Theoretical and Computational Physics

Recently, it has been demonstrated that light-front parton distribution functions and generalized parton distributions can be related to so-called quasi-distributions, which can be calculated nonperturbatively directly using lattice Quantum Chromodynamics, formulated in Euclidean spacetime. This relation is based on the basic assumption that the quasi-distributions obtained using Euclidean correlation functions coincide with those obtained from their Minkowski counterparts, which was recently brought into question. Now, new work has shown that quasi-distributions are indeed identical in Euclidean and Minkowski spacetimes.

Facilities Management and Logistics

First Floor CEBAF Center F Wing Hallway to Close April 8-9 for Construction Work

Environment, Safety, Health and Quality

Resolving ES&H Concerns
To ensure the welfare and productivity of its workforce, Jefferson Lab has several mechanisms for employees, to report issues potentially affecting the safety of workers, visitors, neighbors and the environment, without fear of retaliation or reprisal. ES&H Manual Chapter 2310 ES&H Concern Resolution lists a variety of mechanisms for resolving and reporting ES&H concerns. Here is a list of the options for resolving an ES&H concern:

  • If possible, resolve the ES&H concern yourself;
  • If you are unable to resolve the concern, refer the concern to your supervisor or management chain;
  • Consult with your Safety Warden, Division Safety Officer, a representative of the Worker Safety Committee, or contact an ESH&Q staff member directly;
  • If you would like to remain anonymous, or if you feel that it is more appropriate, use the Jefferson Lab Employee Concerns Program;
  • If one or more of the above steps have not resulted in resolution of the concern, you may also use the formal DOE Employee Concerns Management System hotline at 800-676-3267; or the DOE Differing Professional Opinion Process.

Once your concern has been addressed, communicate any lessons learned to the Jefferson Lab Lessons Learned Coordinator.


Food Services Contract Update: Quark Café Transition
Under new management and a new non-subsidized subcontract, Quark Café opened its doors on Monday, April 3. The cafe is now open 7 a.m.- 2 p.m. The Elite Management Group is excited to be our new food services provider. During the month of April, in an effort to learn our likes and dislikes, Elite will be providing a similar weekly menu in the café and continue to honor promotions, such as “Free Coffee Monday with Purchase” and the “Sandwich Punch Card.” There will also be some new additions and pricing changes, as expected under the new subcontract model. The Elite Management Group welcomes any comments, suggestions and questions. Vincent Savage, the Café Manager, invites the Jefferson Lab community to contact him directly with any feedback by email at, by telephone at x7370 or by simply stopping by the café for a conversation. Savage extends his thanks to guests who have already submitted feedback or concerns. Elite asks for our patience as they continue to transition into their new role here at Jefferson Lab and also asks that you continue to provide the feedback that aids them in being our service provider. Questions and comments may also be directed to the Staff Services Manager and SOTR, Cynthia Lockwood, at or x7389.
