HV conditioning has begins. Vacuum chamber pressure is currently 3.2e-07 Torr on TSG:IG1.

TPS:Q2 and TMS:MB1 failed during the scan. -> restarted.

mass scan crashed due to a network error will be restarted tomorrow

heaters and HV power supplies have been switched off

IG1 5.1e-9 T.

The backing pressure at TSGRP1 does not go below 578 mT. Fault report to vacuum.

turbopumps in mass separator section started after power outages

Wednesday, April 18, 2012, 12:15: Blanked off cooling lines. Chamber ready to be pumped down.

Wednesday, April 18, 2012, 12:16: TSGRP1 makes unusual noise when attempting to pump down vacuum chamber. Roughing aborted for now. Edi Dalla Valle is informed. He will have a look at it after lunch.

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.

Did a local IOC reboot to cure to white-out. The test stand is now operational.

Rick and John installed the ITE-TM4-SiC#27-HP-SIS-May2012 in the Test Stand. Pumping down.
