Publications Refresher Course Set for June 21
The next Publications Refresher Course is set for June 21, 2-3 p.m. in CEBAF Center room F226. Familiarize yourself with the publications submission and approval system, DOE's Public Access program and Jefferson Lab activities to support public access. Sessions last about 45 minutes and include a live demonstration of all aspects of the publications system. If you plan to attend, R.S.V.P. to email@example.com no later than June 20.
History Archives Photo of the Week
This week's photo of the week features the signing of the Memorandum of Understanding between Old Dominion University and CEBAF in 1990. The photo shows ODU Interim President William B. Spong, Jr. and Hermann Grunder.
Center for Theoretical and Computational PhysicsThe production of a particle with large invariant mass M and small transverse momentum qT in hadron-hadron collisions is described by transverse momentum dependent (TMD) factorization. The TMD formula is an asymptotic statement, correct in the limit of very small qT2 / M2. In practical cases, the corrections ~ qT2 / M2 may be sizable. A new paper computes for the first time the leading power corrections to particle production in gluon-gluon fusion.
Chris Curtis will present a paper at the 33rd Annual Coordinate Metrology Society Conference (CMSC) in Snowbird, Utah, on aligning LCLS-II cryomodules. Ron Lassiter presented the NX Beamline Auto-Populate Journaling methodology at the Product Lifecycle Management (PLM) conference held in May. The MSINST group resolved the leak issue with the instrumentation/fittings in the Accelerator-Hall C Dump. The EES RF and I&C groups are supporting general scheduled accelerator down preventive maintenance tasks. The DC Power group is upgrading the low-conductivity water modifications to box supplies and supporting Facilities Management and Logistics staff in south access main 1 and 2 ground fault testing. The EES Support group continues supporting the LCLS-II cavity and cryomodule testing in the Vertical Test Area and the Cryomodule Test Facility. The Safety System group completed certification of the Gun Test Stand. Preventative maintenance was completed to the injector and the Oxygen Deficiency Hazard system, and the group conducted general beam loss monitor maintenance.

Environment, Safety, Health and QualityTemporary RadCon & IH Service Disruptions Begin June 12 Due to ESH&Q Move
Beginning June 12, there will be some intermittent service disruptions as specific work centers in the Environment, Safety, Health and Quality Division move into the new ESH&Q Division building (Bldg. 52).
Radiation Control (RadCon)
There will be no Rad Worker 1 - Practical Factors training available June 12-16; contact Keith Welch, x7212 or 757-876-5342; or David Hamlette, x7219 or 757-876-1743, for emergent needs. Visitor radiation dosimetry may not be available June 14-16; contact Becky Mosbrucker, x7236, for specific needs. The radiological analytical lab will be out of service July 10-17.
Industrial Hygiene (IH)
Expect slower than normal response times for work requests to Industrial Hygiene staff on June 14-15 and June 19-21. No Confined Space Entry support will be available Friday, June 16 and Monday, June 19; contact Jennifer Williams, x7882 or 757-240-0031, for emergent needs.
Please bear with ESH&Q Division staff members as they get their work centers moved into the new building. If you are aware of advance needs – especially for support needed from June 12 through early July, contact your ESH&Q point of contact as far in advance as possible.

Computing and Networking InfrastructureJefferson Lab Campus-Wide Phone Outage Scheduled for Saturday, July 8
Jefferson Lab’s landline telephone system will be down intermittently on Saturday, July 8, 8 a.m.- 5 p.m. The outage will permit equipment upgrades. Across Jefferson Lab, the outage will disrupt landline telephone services, voicemail and fax machine services. This outage will also affect Jefferson Lab and university phones in the ARC, but not the commercial tenants in the ARC.
To Get Help and Report Emergencies During the Outage:
- Use a cell phone to call 911.
- After you are advised to hang up by the 911 Dispatch Operator, immediately call the Jefferson Lab Security cell phone at 757-342-9868. Advise Security of the 911 call, the nature of the emergency and the location of the emergency.
- Or activate the closest fire alarm box if no cell phone or coverage to alert Security of your issue. (Security will send an officer to investigate; however response times will vary.) And if or when possible, follow up with a call to the Security cell at 757-342-9868 to advise them of the situation.
Inquiries during the outage can be made to Jefferson Lab Security’s cell phone at 757-342-9868. For more information regarding this outage, contact the IT Division Helpdesk at firstname.lastname@example.org or x7155.
AnnouncementsJSA Awards Graduate Fellowships for Research at Jefferson Lab
Jefferson Sciences Associates announced the award of eight JSA/Jefferson Lab graduate fellowships to support advanced studies at their universities and conduct research at Jefferson Lab. The students’ research proposals cover a broad scientific spectrum, including experimental and theoretical physics. Read more here.
