 Thursday, July 09, 2015, 14:02, David Wang, Conditioning Station, Development, TM1, , TM1 is pumping down at CS
|
TM1 and CS vacuum system are connected. All turbo-pumps are started. The new TP1S works fine also. The pumping down looks good so far. During the
TM1 and CS roughing down time, Joe .M noticed a Rn-220 level surge up in TH . Then,the Rn220 level slowly dropped back. Anders suspected this Rn-220
surging is related to the TM1 roughing down at CS. We decided we will stop the pumps , vent the CS , and roughing again tomorrow. During the same |

Friday, July 10, 2015, 14:41, Anders Mjos, Conditioning Station, Maintenance, TM1, , Replaced roughing pump
|
| The roughing pump was replaced with a more leak tight pump due to the discovery of Rn-220 migration while roughing on TM1 in TCS |

Monday, July 27, 2015, 17:03, David Wang, Conditioning Station, Standard Operation, TM4, UCx 13, UCx13 and TM4 under vacuum at CS.
|
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. |

Tuesday, July 28, 2015, 10:12, David Wang, Conditioning Station, Standard Operation, TM4, UCx 13, Helium pressure test on TM4 HS line at CS
|
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. |

Thursday, August 13, 2015, 17:17, David Wang, Conditioning Station, Repair, TM2, Dummy target, TM2 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 |

|
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 |
