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.

Did the HV conditioning for the TiC#3 up to 30kV.

Heaters ramp up in progress.

The TSH:TGHT stopped at 263.7A, but the setpoint is still ramping (now at 421A). The voltage is set correctly: have 6.238V setpoint and 4.386V readback. The reading on the Power Supply shows 418A. Through the window the target assembly looks at high temperature. The readback on Epics seems stuck. E-Fault for Controls 6389

Mass scan file: plotdump-local-clean.txt Nov2 12 13-15-59.txt

The scan was taken at TGHT=573A (read from the PS panel) .

The TBHT = 230A

Started the cooldown for SiC#3.

All TPS optics, with the exception of TPS:Q4 cannot be turned off. E-Fault#6395 for Controls.

Same for the TSG optics: CB1, VCB1 and CBC.

Talked to Evgeniy and Kazuya. Optics are OFF now.

Venting the Test Stand.

TiC#3 will be ready to be removed in few minutes. 

Please note: water is still ON.

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

Target installed with 130 in lbs torque on all bolts.

Tuesday, March 26, 2013, 09:11

All P/S switched on.

ISAC Ops will condition this target as a training exercise.

ISAC ops e-log
ISAC ops e-log 2

Wednesday, March 27, 2013, 13:41: ISAC ops called to inform that the target has been cooled down and bias is off.

Thursday, March 28, 2013, 08:22: Closed TPS:IV4 and switched off turbos.

Thursday, March 28, 2013, 13:27: Venting

Thursday, March 28, 2013, 13:33: Water purged

NOTE:

TBHT Power Supply is 600A. EPICS thinks it is 500. Multiply current setting with 1.2 for actual current to the tube.

Time stamp on OM-DAQPRO-5300 is on hour behind (daylight savings).

All bolts torqued to 130 in lbs. TGHT and TBHT bolts tightened and loosened 3x.
