Publications Refresher Course Offered on Dec. 11
Authors who need to brush up on their knowledge of the Jefferson Lab Publications System or who want to know more about DOE's PAGES will want to come to the next Publications Training and Refresher course on Monday, Dec. 11, at 11 a.m. in CEBAF Center room F228. Sessions typically last 30-45 minutes. To attend, send in your advance R.S.V.P. to Kim Edwards at email@example.com.
Center for Theoretical and Computational PhysicsThere are a number of accelerator neutrino experiments, currently running or in the planning phase, aimed at measuring fundamental properties of these particles. The analysis and interpretation of these experiments require a quantitative understanding of neutrino-nucleus scattering. A new paper reports the first ab initio calculation of neutrino inclusive quasielastic scattering from 12C (one of the targets used in the experiments) by neutral current interactions. It finds that the strength and energy dependence of two-nucleon processes induced by correlation effects and interaction currents are crucial in providing the most accurate description of neutrino-nucleus scattering in this kinematical regime.

Environment, Safety, Health and QualityNotable Event Report Complete: Central Helium Liquefier Electrical Conduit
On Oct. 4, a conduit with a 480-volt conductor was pierced during re-roofing of the Central Helium Liquefier 1 (CHL1), causing the power to be interrupted to the CHL1 cold box controls and tripping the refrigerator off. The conduit location on the roof had been marked by the contractor; however, due to multiple communication and process issues, the markings were thought to be incorrect. Further, the electrical line had not been de-energized by the lab prior to the work. Corrective actions include development of a standard procedure for electrical outages, consideration of possible impacts when scheduling activities near operational equipment, and subject matter expert review and approval prior to start of work. The complete Notable Event report can be reviewed online.

SOTR Training Offered Nov. 29 and Dec. 8
The Jefferson Lab Activities Group has posted the details for its next three events. The Toys for Tots Toy Drive is now underway; unwrapped toy donations for children 1-12 years of age may be placed in collection boxes through Dec. 8. The Children’s Holiday Party is set for Dec. 9, and volunteers are asked to sign up early for the event. Finally, entries for the Office Door/Cubicle Decorating Contest should be submitted by Friday, Dec. 15. For all of the details and links, see the full memo.
RadWorker I Training Offered
A Radiation Worker I qualification class will be held 9 a.m.- 5 p.m. on Wednesday, Dec. 6, in the large conference room in Bldg. 52 (ESH&Q Bldg.). If you wish to attend this class, contact Maya Keller as soon as possible at firstname.lastname@example.org or x6021.
Mobile Mammography Unit Onsite Jan. 19, 2018
The Chesapeake Regional Mobile Mammography Unit will be stationed in the ARC parking lot on Jan. 19, 2018. Appointments will be available during the hours of 9 a.m.-3 p.m. Mammography detects breast cancer, and The American Cancer Society recommends scheduling your first or baseline mammogram by age 40. This service is open to everyone, as personal health insurances will be billed. To make an appointment, call (757) 312-6400 or visit the website at www.chesapeakemammo.com.
