12 GeV Upgrade
Preparations are almost complete for a Physics Division Experimental Readiness Review (ERR) of the base experimental equipment in Hall C. This review will focus on the operation of all of the equipment in the hall, including those components provided by the 12 GeV Upgrade, although the superconducting magnets are the subject of separate, dedicated reviews.
The helium leak that was found by the manufacturer of the dipole magnet for the Super High Momentum Spectrometer (SHMS) has now been localized. Part of the dipole's outer chimney can had to be cut open in order to gain access to the leak near the bottom weld joint of a bellows. Specialists will determine whether to repair or replace the bellows in the next few days. The SHMS Q2 magnet has been crated and is fully prepared for shipment from France. All transportation authorizations are in place, and the magnet will leave the factory as soon as a temporary road-closure along its travel route has been lifted (expected within one-two weeks). Its reservation on a ship to Norfolk has already been arranged.

The Electrical Engineering group has been supporting a number of project and lab initiatives over the past few months. All EES groups have been working hard to get the Low Energy Recirculator Facility operational for the DarkLight experiment, which completed its engineering run a couple of weeks ago. The group has also continued to support the 12 GeV project by working on the Hall B Torus and Solenoid magnets and instrumentation. Its members have also continued to install components and systems into the Test Lab for the Upgrade Injector Test Facility project. The main focus of the RF, DC, Safety Systems, I&C and the Support group will shortly move to CEBAF to prepare the machine for the fall physics run.
