Recent tests of a cryomodule that was built and performance tested at Jefferson Lab’s Cryomodule Test Facility has demonstrated world-class efficiency. Read more here.
EXPERIMENTAL NUCLEAR PHYSICS
Experimental Hall A Update
Hall A has uninstalled the novel tritium target, the first deployed for nuclear physics in three decades. This target was used successfully to obtain data for four experiments over this fall and last spring 2018, including two with high-impact ratings. The hall is now focusing on installing the APEX experiment, a dark matter search for a new gauge boson, the A', with sub-GeV mass that couples to ordinary matter.
L’Oréal USA For Women in Science Fellowship Program Now Accepting Applications
The L’Oréal USA For Women in Science fellowship program honors female scientists at a critical stage in their careers with grants of $60,000 each. Since 2003, 75 postdoctoral women scientists have been awarded nearly $4 million in grants. Exceptional female scientists looking to advance their research and serve as role models for the next generation of girls in STEM are encouraged to apply online for the 2019 program by Feb. 1.
THEORETICAL AND COMPUTATIONAL PHYSICS
In the past, experiments have reported two different hybrid-meson candidates that couple separately to the ηπ and η'π channels, which is not compatible with lattice QCD and phenomenological expectations. A new study fits the intensities and phases of the ηπ-η'π system extracted by COMPASS with a coupled-channel amplitude. The analysis provides a robust extraction of a single exotic π1 resonant pole, finding no evidence for a second exotic state, and thus reconciling the experimental data with the theoretical predictions.
Red Cross Blood Drive Set for Jan. 15
An American Red Cross Blood Drive will take place at Jefferson Lab on Tuesday, Jan. 15, 10 a.m.-4 p.m. in CEBAF Center room F113. New and repeat donors are encouraged to attend. Walk-ins are welcome. For eligibility and scheduling information, see the full memo.
IT Division Systems Maintenance Set for Wednesday, Dec. 19, 5-10 p.m.
The IT Division is planning a systems maintenance period for Wednesday, Dec. 19, 5-10 p.m. During this maintenance period, patching and rebooting the MIS backend database servers will result in all MIS applications being unavailable; MIS applications will be back online no later than 10 p.m. In addition, Windows and Linux patches will be released to all Common User Environment-managed desktops and servers. Plan now to reboot your desktop system to finalize patch installation before the holiday break, but no later than Friday, Dec. 21. Finally, there will be intermittent service outages during maintenance and overnight Wednesday as Windows and Linux servers are rebooted to finalize patch installations. If you have any questions or concerns about this scheduled work, contact the IT Division Help Desk at email@example.com or x7155.
Short Network Outage Planned for Wednesday, Dec. 19
The IT Division Network group is planning a short network outage before 7 a.m. on Wednesday, Dec. 19. The outage is expected to be short (less than a minute) and only affect connectivity to central services. All network connectivity will be back online by 7 a.m. If you have any questions or concerns about this planned outage, contact the IT Division Help Desk at firstname.lastname@example.org or x7155.
Office 365 Training Offered Through December
Office 365 email and calendar training will be held at 2 p.m. in the CEBAF Center auditorium every Tuesday and Thursday until the winter holiday break. If you have any questions or concerns about Office 365, contact the IT Division Help Desk at email@example.com or x7155.

Last Chance to Enter Holiday Decorating Contest
The deadline for entering the Jefferson Lab Activities Group Holiday Office Door/Cubicle Decorating Contest is Friday, Dec. 14 at 5 p.m. All employees and users with an office or cubicle at the lab may enter the contest (individuals and groups). To enter, email JAG Chair Dan Moore at firstname.lastname@example.org or x5927. Include your name(s), building number and office/cube location. See the full memo for details.
Ending Soon: Blanket and Warm Clothing Drive for Area Seniors Sponsored by JAG
Help keep a senior warm this winter with your donation to the Peninsula Agency on Aging. Donation boxes are located in the Test Lab kitchenette, MCC control room, CEBAF Center lobby, SSC lobby and the ESH&Q Bldg. through Dec. 14. For more information, contact Becky Mosbrucker at email@example.com.
Site-Wide Information System to Feature CEBAF Status Information
On Jan. 4, the televisions that currently display Site-Wide Information System graphics and announcements will be updated to display accelerator-only content. This graphic content may include information such as the CEBAF Access Status screen, the Hall Current table and the PSS Status graphic. The change will affect the screens located in the CEBAF Center atrium, the Support Service Center lobby, the Hall D Counting House, the Technology and Engineering Development Bldg. break room and the Insight Announcements section of Insight. For more information on the update, contact Lauren Hansen, x7689.
Secure Bulk Shredding for Jefferson Lab Business Sensitive Work Documents
To aid in the proper disposal of business sensitive or other restricted-use JSA or Jefferson Lab documents, secure shredding collection boxes are located in CEBAF Center and the Support Service Center. A contracted service, Shred-it, visits the lab monthly to shred all collected materials. The next scheduled visits are: Jan. 2, Jan. 30, Feb. 27 and March 27. For more information, see the full memo.
