  1185   Wednesday, March 30, 2016, 15:49 David WangAssembly/Bench TestRepairTM2  TM2 Helium spray leak check on solder stems inside service cap on the top of SW silo.

On each water circuit in side the service cap, there are 4 soldering stems which two of them are inside blue nylon insulator and other two are connected to service tray. Each stem has two soldering spots. See attachment pictures for detail location. I sprayed 15 psi helium on each soldering spots on stems  for 20second on each circuit. I sprayed tons of helium inside each blue nylon.No any leak has been found during the check. The leak detector base leak rate:0.0 XE-9 atm.cc/sec, base pressure:0.0X E-4 torr. The circuit which I checked are :TA+, Ta-, Tube+, Tube-, PQ (coil 2), RU( coil1), EE, MSP, GE. The HS and window circuit are opened at this moment so they can not be checked.

I can not start the TCS pumps due to control page white out. Control group is working on this issue.

Control group fixed the white out problem. I started all turbo-pumps. The pumping down is good so far. The TM1 IG1 is broken. I will check it on next Monday. It could be a broken filament. Then, the filament will be replaced.

  1200   Friday, April 08, 2016, 08:13 Anders MjosITE/ITW CoolingMaintenance  High Active Water Resistivity

The high active water resistivity took a long time to recover after the upgrade to the water cooling circuit. The system needed about a month (from end February to end March) to recover to nominal values. See attached plot of archiver data.

TM1 has now been connected in ITW and the water resistivity remains > 8 MOhm cm, which should allow normal operation. However, the resin is suspected to be approaching end of life. Work is ongoing to get a new replacement resin tank.

 Thursday, April 14, 2016, 07:50: RGA on


Friday, April 15, 2016, 08:09 : Ratio between water and air is higher than normal (indicating possible air leak). See attachment. 3.5 more H2O than N2.  (Ratio in TM3 Nov 2015 was 82:1)


 

A leak was found on the o-ring between the module flange and TCS. This could be fixed by cleaning the o-ring and sealing surface. The Window line is not closed and was accidentally pressurized with He on April 25


Tuesday, April 26, 2016, 08:47: David started the water package.


Wednesday, April 27, 2016, 08:15: Switched off chiller / water cooling.

Wednesday, April 27, 2016, 14:41: Switched chiller / water cooling back on.

  1213   Monday, April 18, 2016, 09:07 David WangConditioning StationRepairTM2 venting TCS with argon.

Anders reported a possible air leak on TM2 and TCS by watching RGA  this morning. I found the quick connector on F terminal on the top of the module is leaking air. It is only used as "X" terminal for Febiad without  water. So, it should be blind capped instead of installing a quick connector. It was installed with a  blind cap before. I borrowed it for leak check on coil lines at SHC, but forgot to put it back right away. Instead, I put a quick connector on it later. This caused the problem. Anyway The TCS need to be vented , and a blind cap  will be installed on the F terminal.

2014-04-18, 9:24AM, I changed the quick connector with a blind cap on F terminal. the rough pump is started now.

  1216   Tuesday, April 26, 2016, 10:47 David WangConditioning StationRepairTM2 TM2 leak check at TCS, water test.

The following water circuits in TM2 are connected at TCS and running with water now : target oven+ - ( one circuit), tube heater+ -( one circuit), coil1 and 2(one circuit), MSP, and EE. The HS and window are open circuits now so they can not be supplied with water.  During the check before we knew HS and window circuit were close to perfectly sealed. So, The test result should not be affected without them

The TCS water pumps are started at 8:28 AM. All TCS high vacuum gauge readings are getting slight better after that.
