Monday, September 16, 2013, 17:04: Cleaned GE. Copper shavings were removed from below the guide pins for the Heat Shield. The shavings were sitting on top of the aluminum support.

The coil insulator has been observed to have cracked earlier. 

New calibration of the m/q based on the hall probe after exchanging the controller(MASSOVERQ2). Based on NiO#2-HP-FEBIAD with Ne supplied and ANODE biased to 200V, 30kV Bias.

CONST11 = -16.3929
CONST22 = 0.12481

The Heat Shield circuit can now be separately purged for water. Use valves on heat shield circuit to purge the lines for target exchanges from now on.

All paddle wheels have been rotated to allow trapped air to escape the system more easily.

This morning the turbo was found tripped off. 

The controller was replaced by Edi on Friday.

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.
