The Cu-tubing for cooling the Turbo pumps broke off during disassembly. New ferrules could not be located on site and may have to be ordered.

The system will be left under roughing vacuum over the weekend.

Wednesday, January 29, 2014

Cooling for Turbo pumps reconnected.

CuLCW will be shut off tomorrow. Valved off water supply to MB1 and TSG to minimize air into the system. Turbos are off.

• 2x spacers ITD0468 1/8" THK installed to shift the wire scanner screen closer to the wire scanner. (ITD0469 1/16" THK spacers not used).
• Emittance Rig installed. Manually actuated from out -> in -> out position. No interference observed.
• Replaced two insulators on wire scanner screens that broke in the installation process. New insulators kindly donated from ISIS.
