50 kV stable with less than 1 spark/h during the weekend by RIB obs.
Today 57 kV reached, but observed sparking on the resistors of the new HV cable. The cable will be removed to take out the resistors, before reinstalling
it. |

TM#4 with UC#21 has been moved from the south hot cell to the conditioning station. |
Tuesday, August 29, 2017, 08:59, David Wang, Conditioning Station, Standard Operation, TM4, , TM4 HS line leak checks
|
TM4 HS line leak checks are done, at SHC and TCS. SHC: Helium spray. TCS: Helium pressurize 70psi. LD base LR 0.0 X E-9 atm.cc/sec.
No leak has been found on both leak checks. |
Tuesday, August 29, 2017, 09:01, David Wang, Conditioning Station, Standard Operation, TM4, , TM4 has been connnected at TCS.
|
TM4 has been connected at TCS. TCS water system has been started for TM4. TM4 and TCS vacuum pumping down is good so far. |
Tuesday, September 05, 2017, 06:33, David Wang, Conditioning Station, Standard Operation, TM4, , Turned off TCS water system and vacuum system.
|
Argon vent and disconnect TM4 at TCS. |

TM#3 has been moved from the north east silo to the conditioning station. |
Friday, September 08, 2017, 14:08, David Wang, Conditioning Station, Repair, TM3, , TCS and TM3
|
TM3 is located at TCS and it is pumping down now. TCS water system has been started. All TCS water lines for TM3 module internal cooling are bypassed
and looped at TCS top ground plate. Water only supply to TCS high current conductors. |

|
Preparing vent the TCS/TM3. We will remove TM3 service tray cover plate after venting. |
Wednesday, September 13, 2017, 16:05, David Wang, Conditioning Station, Repair, TM3, , remove Tm3 service tray cover plate
|
TM3 service tray cover plate has been removed. It is bagged and placed to TH b2 level south wall beside the silo. |
Wednesday, September 13, 2017, 16:13, David Wang, Conditioning Station, Repair, TM3, , TCS turbo pumps are started.
|
TCS and TM3 all vacuum pumps are started. Everything is fine. |

Thursday, September 28, 2017, 10:50, David Wang, Conditioning Station, Standard Operation, TM2, , Helium pressure test on TM2 window and HS water lines at TCS.
|
I did helium pressure test on TM2 containment box window and HS line at TCS. @ 70psi helium for 3 minutes, HS:2.2XE-7 atm.cc/sec., Window:1.2XE-7
atm.cc/sec. There is no change on HS. But LR on window is bigger than before that was in E -9atm.cc/sec range. |
Thursday, September 28, 2017, 15:34, Anders Mjos, Conditioning Station, Development, TM2, , Changes to MP3 startup
|
Due to problems with the regulating valve WPV1, the VFD (Variable Frequency Drive) for the pump has been programmed to do a slow (2 min) ramp up.
WPV1 has been bypassed and left fully opened. Work was done by Dave Morris |
