12 GeV Upgrade
The scope for the 12 GeV Upgrade accelerator DC power subsystem is nearly completed. A handful of 20 Amp trim power supplies need to be installed and checked out on the Hall B beamline (known as 2C) and on the Hall C beamline (known as 3C). The box power supplies for 2C and 3C have been tested into resistive loads. Connections to magnets, Personnel Safety System certification and final tests are taking place this week. The subsystem for Instrumentation and Controls/Safety continues their work on the fast feedback and nano-Amp beam position monitor system for the beamline to the Hall D tagger.

Center for Theoretical and Computational Physics
A derivation of the cross section for semi-inclusive charge-changing neutrino scattering from nuclei is presented in a new paper. Unlike some previous analyses, finite masses are kept for all particles involved in the reaction. The general lepton and hadron tensors obtained are relativistically covariant, and the final cross section expressions are presented for the case where a charged lepton and a charged hadron are detected.
The Machine Shop is working on the following projects:

July 2: DOE Inspector General Awareness Briefing
Environment, Safety, Health and Quality
Utilities and Infrastructure Modernization (UIM) Work and Crews
You may see various York River (electrical contractor) vehicles and support equipment around the site. Be sure to give these contractors room to maneuver trucks and other equipment, especially in the early days of this effort as they learn their way around our buildings and roadways. The second phase of the project will occur in summer of 2015.
Computing and Networking Infrastructure
To assist with an easy migration, there will be training sessions held on July 10 and July 23 at 2 p.m. in CEBAF Center room F113. ReadyTalk was mainly used for audio conferencing, therefore, audio conferencing will be the focus of these training sessions. There will be time at the end of each session for all questions regarding BlueJeans (H.323, web conferencing, etc.). To learn more, visit the BlueJeans webpage for information on logging in and configuring BlueJeans with your Jefferson Lab computer account.
Reminder: Renew Your SmartCard Now
To avoid problems and delays, be sure to have your card renewed before July 11. Once the expiration date passes, the card will no longer work, and the user will not be able to log in to Jefferson Lab systems using the card. If you have any questions or concerns, contact the IT Division Helpdesk, x7155.
