12 GeV UpgradeThe stacking of the lead-glass shower counter for the Hall C Super High Momentum Spectrometer into its final position within the shielding has begun. Each layer of counters is being tested with cosmic rays as they are installed, prior to installing the subsequent layer. The mirror blanks for the noble-gas Cherenkov counter have arrived at CERN, where they will be aluminized and coated. The gas vessel for the noble-gas Cherenkov is being constructed and should be ready for the mirrors prior to their return. Work on services for the SHMS platform continues, with recent emphasis on completing wiring and power cabling, preparing position readback, checking out the new magnet power supplies, and routing in the low-conductivity water.

Center for Theoretical and Computational PhysicsLattice QCD is a computational method for determining the physical consequences of continuum Quantum Chromodynamics (QCD). A new review article discusses the sources of numerical uncertainties inherent to this approach and shows how they can be controlled in order to obtain the universal predictions of QCD. Lattice QCD therefore holds the promise of uncovering the properties of matter under extreme conditions, nuclear forces, the structure of nuclei, and the spectrum and structure of hadrons.

Keep Halloween Safe
Some local municipalities have established trick-or-treat times, while others allow the festivities to begin at dusk. You can find a list of established times for local areas here. Be aware that trick-or-treating in all local areas concludes at 8 p.m., and only children aged 12 or under may participate. If you have children of your own who plan to trick-or-treat this year, check out these safety guidelines from the Centers for Disease Control.
Computing and Networking InfrastructureBrief Internet Outage Set for Thursday, Nov. 6
There will be a brief interruption in the lab's internet connection Thursday, Nov. 6, at 5:30 p.m. The total outage time is expected to be no more than 10 minutes. This outage is being scheduled to accommodate equipment upgrades. If you have any questions or concerns about this outage, contact the IT Division Helpdesk at x7155 or email@example.com.
Thanksgiving Buffet in the Quark Café
The next American Red Cross Blood Drive will take place Friday, Oct. 31, 10 a.m.-4 p.m. in CEBAF Center room F113. New and repeat donors are encouraged to attend. All those who donate will be entered into a drawing for prizes from the American Red Cross. To schedule an appointment, visit redcrossblood.org and enter Sponsor Code: TJNAF. You can also contact Johnie Banks, firstname.lastname@example.org or x7539. Visit the website for donation eligibility requirements.
Share Your Photo for Veteran’s Day Tribute
Jefferson Lab will again recognize its veterans on Veterans Day, Nov. 11 with a small display. This year, a photo exhibit of lab veterans in uniform is being prepared to highlight employees’ service. If you are a veteran and would like to participate, email or bring in your military service photo to Mike Robbins, CEBAF Center room C222 before Oct. 31. These photos can be of any time during your service, from boot camp to retirement. Under the photo, your name, branch of service, and years of service will be displayed.
