  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.

 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.

I did a ITW water signals interlock check with ISAC opp. They are checked once a year before first beam on.

2016-04-13 Same test is done on ITE also. Everything is good.

  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.
