Restarted TM1 and CS turbo pumps after the power off. Everything is fine . |
Thursday, March 06, 2014, 14:12, David Wang, Conditioning Station, Standard Operation, TM1, , TM1 air to vacuum and water lines leak check at CS. 8x
|
TM1 air to vacuum and water lines leak check at CS are finished this afternoon. The leak detector is hooked directly to TM1 service cap so the base LR at LD is 0.0xE-9 atm.cc/sec. I sprayed helium to all air to vacuum seal on the service cap, also applied 70 psi to all water lines(except HS) for 2 minutes each. There is no any tiny response had been found on LD. So All TM1 water lines(except HS) and air to vacuum seals are leak free. The HS circuit can not be tested at this time since the VCR caps are not installed. The turbo pumps at CS and TM1 will be turned off before I leave. See attachment pictures. |

|
TM4 with Ta#42 was HV conditioned to 35kV with the optics tray at 17.5kV. There was some vacuum response while ramping but well within normal. Attached is a screen shot and the associated data. |

Thursday, April 10, 2014, 14:03, Bevan Moss, Conditioning Station, Standard Operation, TM3, TiC#4, HV conditioning
|
The TiC#4 target that is on TM3 was conditioned to 25kV today with the EINZEL lens at 12.5kV. There was one spark shortly after reaching 25kV that reset the bias PS and another one after the module sat at 25kV for ~30 minutes. Attached is the strip tool data and screen shot. Prior to starting the conditioning the power on the chiller needed to by cycled as the VFD on the fans had tripped due to a recurring inrush problem. |

Thursday, July 17, 2014, 10:13, David Wang, Conditioning Station, Standard Operation, TM1, , Leak check on TM1 HS water line with new target installed
|
Chad and I leak checked TM1 HS waterline with new target installed at SHC. The LD base LR:0.0xE-9atm.cc/sec, base pressure: 0.0xE-4 torr. Chad sprayed helium on both VCR fittings and flushed helium around the target. No response has been found on leak detector. The target HS line is leak tight so far. I will do helium pressure test on this line at CS on next Monday. |
