The Conductor insulating blocks - ITD053C and ITD054C - that secure the target heater and coil conductor blocks were replaced. The existing ones were cracked and fell apart upon removal.

Pressure around 140 mTorr. The pressure started increasing early November 2nd. Will continue to monitor.

Tuesday, November 12, 2013, 09:51 UPDATE
 Backing pressure further increased to ~ 350 mTorr over the weekend. Vacuum group has been informed and will replace the pump this week.

 The backing pump (TSG:RP1) was replaced yesterday by Anthony Ip. Backing pressure is down to 1 mTorr on TSG:CG1A

Since yesterday around 4pm. Due to attempt to use the TMS:ER0 device.

IOC rebooted this morning. Archivers restarted.

Impedance measured on TGHT and TBHT (~2.5 mOhm and ~2.0 mOhm). Readback on TBHT gives an impedance of ~2.5 mOhm. This is higher than the previous test. Local current on TBHT shows 60A more than the readback at 300A.  The vacuum did not come down as low as usual, which likely means there is a leak.

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.

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.
