12 GeV Upgrade
The 12 GeV long-term installation activities are coordinated through monthly progressing and weekly planning meetings of the Long Shutdown team. Integration of the 12 GeV Hall B and Hall C installation schedules is planned for the upcoming months. Monthly meetings with Facilities Management & Logistics continue to ensure coordination and support for 12 GeV facility-supported activities. Installation activities at Hall D continue to increase and are coordinated through the Hall D work coordinator.

W&M Colloquium to Discuss CDF at the Tevatron
The FEL Personnel Safety System certification was completed in preparation for gun high-voltage processing. Steve Benson attended the 8th Annual DOE Laser Safety Officer Workshop at SLAC; Gwyn Williams gave a colloquium at George Washington University; and George Neil attended meetings at Shanghai Institute of Applied Physics.
The Safety Systems group continues 12 GeV Upgrade work on the North Linac and Hall D safety systems. Installation of the Hall D oxygen monitoring and alarm systems has started, along with work on the Tagger/Hall D access room interlocks. Design modifications for the superconducting radiofrequency Vertical Test Area PSS are underway. Changes will add new dewar shielding controls and a touch-panel interface.
The DC Power group continues with 12 GeV Upgrade cable installation, procurement tasks for new power supplies, and equipment upgrades to the trim and shunt system. The RF group has resumed preparations for installation and commissioning of the six remaining 12 GeV RF systems. Fabrication shop personnel continue assembly of 12 GeV subsystem elements. Meanwhile, the support group's electricians have been busy installing tray and box duct in Hall D enclosures, completing the final AC electrical configuration for the low-conductivity water systems in the accelerator, and hooking up power to new 12 GeV equipment.
The Instrumentation and Controls group has concentrated its efforts on 12 GeV beam position monitor fabrication, testing and installation. Completed equipment includes 30 strip line BPM cans, with 10 units with fully characterized field maps. Other activities in progress are: first article testing of the BPM receiver electronics, assembly of first article IF modules, Arc 10 BPM cable terminations and the completion of Arc 10 super multiplexers.
Finally, 10 members of Electrical Engineering Support are currently assigned to other groups. They are working to assist in equipment tear out and installation in the accelerator tunnel and in Hall B for the CLAS decommissioning and cable removal tasks.

Tracking Thomas at JLab
Congratulations this week go to Brita Hampton, Samika Hawkins and Ryan Bodenstein, who were the first to correctly identify the location for Sept. 12. Honorable mentions go to Michael Haddox-Schatz, Doug Higinbotham and Harry Fanning. Check out the Tracking Thomas webpage for a better view of his last location and this week's new mystery photo.
