Thursday, September 13, 2012, 08:16: Opened up cooling water. Vacuum (IG1) increased from 5.9E-7 to 6.2E-7 before returning to 5.9E-7. Similar response on IG6 (valve closed). Response is however similar to previous (short time ~5 min) vacuum fluctuations.

Target cooled down. Power supplies off.

 Friday, September 21, 2012, 08:19: Cooling water on. Vacuum stable at 2.3E-7 torr.

Backing pressures TSG:CG1A/B are fluctuating between 0.02 and 0.05 since Sept 17th at ~17h. Expected values <0.01.

 Test stand was off this morning and EPICS controls in "white-out". Controls is looking into it.

Update  13:51:

Controls have reestablished contact with the PLC.

See e-fault 6329

Tried to start the pump from another power outlet with Edi. No luck. Pump will be replaced tomorrow.

Target looks OK. The right leg was a bit much out of center and will be adjusted in the lab.

The torque required to loosen the bolts were measured (from left to right):

Target legs: 48 and 30 in lbs

Tube htr: 25, 30 and 25 in lbs
