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.

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

IOC rebooted this morning. Archivers restarted.

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

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.

HS line is looped. Cu-test bars installed on TGHT and TBHT. Torqued all bolts  to 120 in lbs.
