In Hall C, the Q-weak collaboration has submitted a paper for publication: "First Determination of the Weak Charge of the Proton." The article is based on 4 percent of the data accumulated during the Q-weak run.
Michelle Shinn gave two public talks at the National Radio Astronomy Observatory in Green Bank, WV, to a large audience. Members of the FEL team provided expertise for a successful test of a superconducting radiofrequency gun at the University of Wisconsin, Madison, which is partially funded by the Office of Naval Research. The sample titanium ring that the segmented insulator vendor sent for quality assurance testing has been surface characterized. The FEL team will have a conference call with the vendor and Jefferson Lab procurement early next week to find the most suitable way to improve the surface finish of the rings. System engineering and simulation continues for the buncher cavity, which was purchased with money from the Commonwealth of Virginia. The final design review for the U24 undulator being purchased for Los Alamos National Lab was held this week, with attendees from STI Optronics and LANL.

Work Control Documents Update
If you are the owner of such documents, now may be a good time to review whether these documents need updating. These documents may need updating if they have expired or been made obsolete due to the elimination or addition of equipment during the shutdown. Alternatively, a document could have already been reviewed during shutdown activities and has been determined to still be valid as written, but needs to be validated. Take a few minutes now to make sure your Work Control Documents are in the latest format, signed and ready to go, and workers who are using the documents are educated about any updates, changes or additions.
