Center for Theoretical and Computational Physics
A recent paper reported the first study of the gluon structure of nuclei up to atomic number A = 3, using lattice quantum chromodynamics calculations with unphysical large values of the heavy pion mass. Nuclear modification of the gluon momentum fraction quantity defines a gluonic analogue of the EMC effect and is constrained to be less than approximately 10 percent in these nuclei, consistent with expectations from phenomenological quark distributions and the momentum sum rule. The first moment of the gluon transversity structure function in the spin-1 deuteron is found to be non-zero, providing the first indication of gluon contributions to nuclear structure that can not be associated with an individual nucleon.
Facilities Management & Logistics
Restroom Lockers for Day Use Only
Members of the Jefferson Lab community are reminded that the lockers located in restrooms, in all buildings, are intended for day use only - contents and locks should be removed daily; the lockers are not meant for overnight storage. Facilities Services staff posted signs on Monday, advising individuals that beginning Friday, Sept. 29, locks left on lockers in the restrooms adjacent to the Fitness Center (rooms 2556 and 2557) overnight will be cut off and locker contents will be removed. Locker contents will be held, so that individuals may claim their property. Unclaimed items will be discarded after a couple of weeks. For more information, contact Mike Lewellen at email@example.com.

Fitness Center Safety and Hygiene Reminders
All Jefferson Lab staff and visiting scientists, 18 years of age and older, may use the Fitness Center located in Room 2558 in the Technology and Engineering Development building, Bldg. 55. It is open for use seven days a week from 6 a.m. – 8 p.m. When using the facility, read and heed equipment-use instructions and all posted notices. To keep the equipment in safe and good working condition:
- Don’t use equipment if it is broken.
- Report all broken or non-performing equipment by calling ext. 7400.
- Return all equipment to its place when done using it.
- Individuals must wipe down any equipment that they use with a disinfectant (provided).
Use of the facility is at an individual’s own risk. Everyone should consult their physician before beginning any exercise program. If an injury or health emergency occurs in the Fitness Center, call 911. For more information, see the full memo.
Computing and Networking Infrastructure
Use On-Hook Dialing to Stop 911 Misdials & Wrong Numbers
The Telecommunications staff encourages everyone at Jefferson Lab to use the on-hook dialing feature available on the Cisco IP phones to eliminate 911 misdials and to reduce instances of misdialing other phone numbers. With the phone receiver/handset on-hook (hung up), dial in the number to place your call. Carefully check the number to make sure it is correct. Then pick up the handset, and the phone will automatically dial what is on the screen. If you misdial a number, press the button just below the back arrows, <<, visible on the display screen to delete the mistake. For more information, see the full memo.
Test of Public Address System Set for 5:30 p.m. Today
On Wednesday, Sept. 27, members of the Jefferson Lab Emergency Management Team will conduct the recurring test of the lab’s Public Address (PA) System – the live audible announcement feature – available through the Cisco phones. No actions are required or expected from members of the lab community with this test. The test interrupts any in-progress call on a Cisco phone, with active calls automatically put on “hold.” For more information, see the full announcement.
United Way Annual Ice Cream Social Set for Oct. 9
The entire Jefferson Lab community is invited to kick off the annual United Way of the Virginia Peninsula Campaign with an Ice Cream Social. The social will be held Monday, Oct. 9, in the CEBAF Center lobby at 11:30 a.m.- 1:30 p.m. This year, members of lab leadership will be on hand to serve up ice cream and dress it with your favorite toppings. Donate just $1 per scoop (up to 3 scoops per bowl). All proceeds will go to the United Way of the Virginia Peninsula. The food is being generously donated by our Quark Cafe contractor, Elite.
Vacation Donation Program a Success!
The Human Resources department is pleased to announce that at the conclusion of the vacation donation enrollment, 500 vacation hours had been donated. Once again, the laboratory will be able to provide financial assistance to the very grateful employees that qualify for the program. Thank you all for your generous support!

As you schedule your appointment, keep in mind that for 15 minutes after vaccination, you should remain at Jefferson Lab in the presence of other people and avoid safety-sensitive activities, including driving. If you would like to be vaccinated or have any questions about the vaccine, contact Occupational Medicine at x7539 or x5585 to schedule an appointment.
Plan Now for the JAG Fall Festival on Nov. 1
The Jefferson Lab Activities Group will be hosting a Fall Festival and Picnic on Wednesday, Nov. 1, on the Residence Facility field. All Jefferson Lab staff, users and their families will be invited to the event, which will be filled with food, fun and prizes. This year, the event will feature two activities that will require advance planning by participants, a Homebrew Beer Competition and a Trunk-or-Treat Contest. For details and instructions for entering these events, see the full memo.
