12 GeV Upgrade
Reserve Your Space in the ARC Library
Users coming to JLab for a stay of short or intermediate duration now have an attractive option for work space: The newly refurbished user space in the ARC building library. This space features 36 work stations with L-shaped tables and comfortable chairs, Ethernet ports and WiFi access. Several work stations have been equipped with Linux computers (providing access to the lab's internal network) and telephones. Lockers are available to securely store personal items and equipment. A virtual tour of this space is available. Reserve a space online before your next visit with your JLab username/password. For help with reservations, contact Lorelei Chopard.
Center for Theoretical and Computational Physics
One of the most important questions in nuclear physics is the role of color gauge invariance. The so-called "Sivers" distribution function presents an ideal testing ground for measuring the consequences of this invariance, as the function depends non-trivially on the color. A new paper finds that the Sivers function exhibits process dependence by comparing semi-inclusive deep-inelastic scattering data with proton-proton jet asymmetries. JLab measuremets at 12 GeV in the region of large momentum fraction x will be crucial for further confirmation of this finding.
The Machine Shop is presently manufacturing or continuing to manufacture:
Hall-B’s CLAS 12 High Threshold Cerenkov Counter Mirror assembly jig sections. There are 12 sections that are made out of LAST-A-FOAM®. These parts are bases for the mirror sections of the HTCC.
Two septum dipole vacuum chambers for the MYA septum magnets (multi-beam dipole magnets).
Three vacuum chambers for the ZA magnets, which will receive multiple-beam passes.
The shop has completed machine work on all magnet cores for the 12 GeV Upgrade project. The shop has processed 132 job requests since Jan. 7.

Environment, Safety, Health and Quality
A new program named "Martha" now makes it easier for staff to access ES&H process and procedure information quickly and efficiently. Martha is now available from the JLab Insight Page; it has also been linked to the JLab Task Lists via the Hazard Identification Worksheet Questions. Check it out, and send your comments and questions to email@example.com.
Computing and Networking Infrastructure
Computer User Account Audit
The annual Computer User Account Audit began Feb. 18. All supervisors and sponsors of users with computer accounts at JLab are required to review and re-authorize these accounts. This audit is a critical part of maintaining an appropriate level of cyber security at JLab. If you have any questions or concerns regarding the audit, contact Jessica A. Perry, x7262.
Toys For Tots Toy Drive Planned
As in years' past, JLab will participate in the U.S. Marine Corps' annual Toys For Tots toy drive, beginning in late November.
Children’s Holiday Party Set for Dec. 8
The Jefferson Lab Activities Group is hosting the Children’s Holiday Party on Saturday, Dec. 8, 10 a.m.-1 p.m. in the CEBAF Center lobby. All children of JLab employees, contractors and users are invited. Each family is asked to bring a new, unopened toy donation for Toys For Tots. Santa Claus plans to drop by with JAG Dog Training Club member, Dan Young, Physics Division, and his two Samoyeds, Nikko and Tally (aka JLab's Santa dogs), for photographs and messages from the children. Games, craft activities, light snacks and drinks will be provided. All children must be accompanied by an adult.
Lab Scientists and Administrators Invited to Virginia STEAM Academy Colloquium
Everyone at JLab is invited to a talk about the Virginia Science, Technology, Engineering and Applied Mathematics (VA STEAM) Academy at 3 p.m. on Monday, Nov. 26, in the CEBAF Center auditorium. Judy Stewart, VA STEAM Academy co-founder, will discuss the creation, development and critical need for the academy, which is slated to open its doors to its first freshman class in 2014. The four-year residential program is intended to be a uniquely challenging experience for high-school students with ability and potential in science, engineering, or math. A VA STEAM Academy and JSA/Jefferson Lab Memorandum of Understanding (MOU) will be signed just prior to this colloquium, to establish a partnership that will provide outstanding educational opportunities to VA STEAM faculty and students. Cookies and coffee will be served in the CEBAF Center lobby beginning at 2:30 p.m.
Tracking Thomas at JLab
Little Thomas is visiting all corners of the JLab campus. If you can identify his location this week, email Kandice Carter with your guess. Guesses are accepted through Friday.
Congratulations this week go to Doug Higinbotham, Annie Tran and Samika Hawkins, who were the first to correctly identify the location for Nov. 14. Honorable mentions go to Ron Bartek, Isadoro Carlino, Narciso Gomez, Marcy Stutzman, Harry Fanning, Kelly Tremblay, Kevin Banks, Robert Martin, Elaine Zuchowicz, Michelle Shinn, Debra Brand and Dick Owen. Check out the Tracking Thomas webpage for a better view of his last location and this week's new mystery photo.
