TM2 was connected yesterday by Frank and Anders. The West side panel with IG1S on Exit Module 2 was replaced with a new SST panel with 1 CF flange only
(dwg). Link to check list on DocuShare. |

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 |

The pumping down on TM2 at CS was good overnight. However, the back up line pressure is still too high for LD to get to 0.0-E-9atm.cc/sec . It only could
get to 1.2xE-7 atm.cc/sec. It is not enough for a good leak check . I dont want to have any ambiguous situation on this" D" line leak check.
So,I am going to reconfigure the leak detector to the spare KF25 pot on the TM2 service cap. All pumps are stopped . The CS and TM2 will be vented soon. |

TM2 at SMP under vacuum. TM4 at silo. Frank and I did the tests. Everything is fine on TM4 check. On TM2, all mega test at 500V
are around 200K ohms which is so abnormal. We will move TM2 to TCS and start investigation there. |

Fiberglass that fell out yesterday was put back in place (as well as possible).
Cleaning took place this morning with excellent results. Cleaning was performed with red scotch brite on the cleaning tool, air pressure at 40
psi while running, with one 60 second cycle. Three blocks (EE, HS and Window) needed a second pass to remove the indium. |
