The target heater power supply at the teststand has been removed to replace one in ITE.

ramping up target to 300 A and tube to 270 A

switched everything off to prepare for scheduled power outage on Monday

Friday, January 18, 2013, 11:28: turbos stopped

Wednesday, December 19, 2012, 16:24:

After long power outage, everything is off except the roughing pumps. Two turbo pumps (TMSTP2 and TSGTP1B) have shown fault due to timeout, only TSGTP1B could be reset, while TMSTP2 is still showing this fault

Vacuum in Magnet section is 0.004T according to TMSCG2. Since the target chamber was vented to remove the RFQ tests target, this section is actually pumped down using the roughing pumps (water lines are blanked off)

archivers started

I was now able to reset TMSTP2.

closed the roughing pumps to the target chamber, vacuum at 0.027T

purged Ne line and started cathode heater ramp up to 295 A

heater ramping up again with Ne leak closed.

start mass scan to do new mass calibration

start cooldown. Found computer at teststand off. Somebody tried to login with username ARIEL.

A big vacuum excursion tripped the source off at about 1am. The vacuum did not fully recover afterwards only down to about 1.3e-6T. Ne leak has been closed and vacuum went down to 6e-7T within a few minutes. After the trip the current of the magnet stayed constant. Fluctuations may have been caused by high voltage sparks.

tube heater ramping started

A short in the anode has developed during the heater ramp up. Increasing the current limit did not cure it. Start heater ramp down to investigate.

 Wednesday, July 04, 2012: short found between anode and target. probably caused by the target tube coming in contact with the anode due to bending of the tube caused by heating and deformation of the grid retaining ring. see attachements

mass scan is finished and saved see attached.

A new Heatshield waterline loop was manufactured and installed to replace the old one which had a leak.

Chamber vacuum currently being roughed down.

Wednesday, March 12, 2014, 10:41: Started turbos.

Wednesday, March 12, 2014, 10:5:0 Turbos at speed. TP1A timed out once.

Wednesday, March 12, 2014, 10:51: Vacuum at 2.6E-5 T.

Thursday, March 13, 2014, 10:20: Opened water. Vacuum stable at 9.3E-7 T.

Venting chamber to investigate slow pump down.

connected A(CH3)3 instead of He, pumped line and valve with pump on the high voltage rack.. Opened regulating valve first response at mass 27 with valve set point at 7.0.

 The bottle with Al(CH3)3 was removed from the test stand yesterday April 25.

comments in e-mail from Marik:

Anders & I took the Al(CH3)3 bottle out of the test stand & put it in the middle fume hood of lab 07.  There was some puffs of white "smoke" when Anders unscrewed the VCR coupling.  Likely some trapped liquid that oxidized on air exposure.  If at all possible, I would suggest a vertical orientation in the Faraday cage.
