|
TM1 inside service cap surface and shielding plug surface are visually inspected yesterday. No rust has been found. I cleaned all rust on top of TM1
today. Rust on TM1 silo top plate are cleaned as well. |

Installation by Marshall. Dave M from controls adjusted circuitry to get TCS:MP1 to start.
Work is being done in preparation for the Module Move Ventilation SAS project |
Friday, April 07, 2017, 09:53, Travis Cave, Conditioning Station, Maintenance, TM1, no target, Electrical Check and TM1 other checks 
|
Results of an electrical check on TM#1 with no target attached to it.
I use this e-log entry for TM1 notes as well 1. TM1 IG1 is a dual filament gauge . Its filament is very close to grid now. It shorted
one time during the pumping down. It still works fine so far . But, we may need to change it if we use this module in TS again. |

Monday, April 10, 2017, 11:23, Travis Cave, Conditioning Station, Standard Operation, TM1, no target, Module move
|
TM#1 has been moved from the conditioning station to the north west silo. There was a slight delay in the move as the limits for the hoist
drum got way out of whack and had to be adjusted. |

|
| TM#2 with Ta#51 has been moved from the south hot cell to the conditioning station. |

Tuesday, April 11, 2017, 14:06, David Wang, Conditioning Station, Standard Operation, TM4, , SHC, TM2 leak check on HS line.
|
| Chad and I did leak check on TM1 HS line at SHC. 0.0XE-9 atm.cc/sec. No leak. |
|
Wednesday, April 12, 2017, 07:26, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 and TCS vacuum system has been connected.
|
| Roughing down overnight. Turbo pumps are started this morning. Everything looks good so far. |

Friday, April 21, 2017, 08:19, David Wang, Conditioning Station, Repair, , , Low frequency on TCS TGHT flow sensor.
|
Anders and I found a low frequency issue(13hz only) on TCS TGHT flow sensor when doing TM4 conditioning. By trouble shooting, We found the module water
lines are good. the restriction cause this problem in on TCS supply or return water lines to TGHT. I switched TGHT lines with MSP water lines. The
wheel frequency on TGHT is 67.0hz which is pretty high. Now, MSP is using the original TGHT water line(flow sensor frequency 13hz). Flow sensors and |

Monday, April 24, 2017, 09:52, David Wang, Conditioning Station, Standard Operation, TM2, , Switch off TCS water system and vacuums
|
| The TCS bias was turn off before that. The TM2 and TCS are still under vacuum now. |
|
Monday, April 24, 2017, 16:11, David Wang, Conditioning Station, Standard Operation, TM2, , TCS TP1s is restarted.
|
TCS IG1S is switched on as well. The reason to start the pump is to prepare a possible extended TM2 conditioning at TCS caused by TH crane issue.
TCS:TP1 and TP2 are not switched on for this. |
|
Friday, April 28, 2017, 12:04, Anders Mjos, Conditioning Station, Maintenance, , , MP1 problem
|
TCS:MP1 was tripping of intermittently yesterday. It was found by Dave Morris that the current sensor was not set correctly causing the pump on status
to flicker at times. Dave adjusted the settings yesterday. The system should be operational and is currently running normally. |

Thursday, May 04, 2017, 14:06, David Wang, Conditioning Station, Repair, TM3, , A vacuum to air leak on TM3 service cap round side panel was found and fixed..
|
During TM3 roughing down yesterday afternoon,The vacuum gauges CG1 and CG1S stopped at 1.20 torr and refused to drop down. Leak detector was used to
found where the problem was. LD was in rough detecting mode and showed 2.7xE-6 atm.cc/sec as base leak rate. Spray medium amount of helium to TM3
service top, and found this leak was on round panel of TM3 side wall. LR climbed to E-4 atm.cc/sec range on helium spraying. In my vie,One 10# socket head |

Thursday, May 04, 2017, 19:10, Aurelia Laxdal, Conditioning Station, Repair, TM3, no target, TM3 HV test at TCS up to 50kV
|
Today TM3 was conditioned up to 50kV. At 50kV sparking started and to go higher in voltage it needs more conditioning time. Lowered it to 49kV for the
night. |
|
Friday, May 05, 2017, 11:53, David Wang, Conditioning Station, Repair, TM3, , sparking on TM3 serice cap top.
|
Sparking was found this morning inside HV cover on TCS in TH while TM3 was HV conditioning at TCS. The TCS bias was set to 50KV when I found this spark.
It sparks between HV cover front side wall to a KF 25 clamp on HS water terminal. The KF 25clamp is used in this situation on HS water line top because
the HS line is opened inside module, and we need a vacuum seal on the top of this line. Actually, The clap is much smaller than the corona ring on |
|
Friday, May 05, 2017, 19:36, Aurelia Laxdal, Conditioning Station, Repair, TM3, no target, TM3 HV test at TCS up to 65kV
|
Today TM3 HV conditioning went up to 65kV. I'll leave it here over night. ISAC OPS have instructions to keep an alarm on the HV, and ion gauge and turbo
pump (TP2 tripped 3 times due to sparking). |
