I connected the CS  vacuum system  to TM4. The CS and TM4 turbo pumps are started. Everything is good so far. The HS line will be pressured with helium tomorrow for leak checking. The CS and TM4 will be vented with Argon on Wednesday morning as planned before moved to ITE.

I did the helium pressure test on TM4 HS line at CS. Applied 70 psi helium  2 minutes. base leak rate0.0x E-9 atm.cc/sec.  No response during the test. No leak.

  1037   Thursday, August 13, 2015, 17:17 David WangConditioning StationRepairTM2Dummy targetTM2 at CS

TM2 has been moved to CS. All turbo-pumps have been started. The pumping down is good so far.  I connected the leak detector to service cap, and finished the leak check today.  The LD base LR:0.0Xe-9atm.cc/sec. 80psi helium were applied to coil1, coil 2. HS and window circuits, each for 2minutes. No any response has been found on LD. So all water lines are leak tight now. I also sprayed   helium to top service cap checking all air to   vacuum seals. They are all good either. But, The new installed PGN1 does not work. Other thing need to mention is The TP2 is running at 2.45A which is 1A higher comparing to TP1. It need to be monitored to see if we have to replace it or not. The high current cables and water lines will be connected tomorrow morning.

  1038   Friday, August 14, 2015, 10:00 David WangConditioning StationRepairTM2 Started CS water package for TM2

I finished the rest TM2 connections to CS, and started CS cooling package. Everything works fine so far.

During the TM2 HV test at CS, It failed. In order to confirm there is no any water leak inside the module after the heaters and beam extraction test, I disconnected all the water lines on the TM2, and purged the water lines with pressure air. Leak detector was reconnected back to the TM2 service cap, and all water lines are pressurized with 80psi helium again each for 2 minutes.No any leak had been found during the test. All the water lines are still perfectly sealed. Also, I checked all the vacuum to air seals on the top of the module.They are good either.  Anders used the RGA  tracking the helium during the test. No leak.
