High Voltage (HV) testing was completed on TM1 today. Vacuum was very good 1.9 x 10^-7 T in the service cap, 3.2 x 10^-7 in the containment box,
and 2.0 x 10^-6 in the secondary. The voltage was successfully brought up to 27kV with a current draw of 0.12mA and o sparking. At the next step, 30 kV,
the current draw was above 0.3mA and sparking was beyond 20 sparks per minute. The module should not be taken above 27kV. There is the possibility this |

|
Hi Remote Handling,
The guage on the IMC circuit in the Target Hall is reading atmosphere, and the bellows is currently relaxed (i.e. expanded), whereas it should
be reading about -20inHg and the bellows should be contracted (i.e. compressed). |

I pumped down conditioning station IMC today. The inside bellow pressure is -20 psi on the gauge.Visually checked the bellow before and after pump.The
bellow is in retracted condition now. |

Tuesday, April 03, 2012, 12:11, David Wang, Conditioning Station, Development, , , leak check on conditioning station vacuum system
|
I did a leak check on conditioning station vacuum system today.The vacuum system had been roughed over night . This morning before the leak check,the
convectron gauge reading on emittance box is 20m torr which is reasonable. I hooked the leak detector to system (without turbo pump on)
. The leak detector showed base LR 6.3xE-8 atm.cc/sec. At this base LR, I found 2 leaks up to low E -6range on that cross tube flange to small turbo pump, |

TM1 moved to conditioning station to today. After moving, I connected the vacuum system which include all gauges ,vacuum lines , controllers,and fans.I
started roughing the station through two turbo pumps(on TM1) . After 2 hours roughing, the station vacuum went to 100 mtorr. I started TP1 and TP2 on TM1
and turned on 3 gauges (png1 on service cap, ig1 on service cap ,and png4 on emittance box) . All turbo pumps and high vacuum gauges work fine .The |

Monday, April 16, 2012, 16:17, Bevan Moss, Conditioning Station, Standard Operation, TM1, No Target, High Voltage Test
|
A high voltage test was completed on a target free TM1 in the conditioning station. Only the turbo pumps on the target module were operational
due to phase 2 construction. Testing started at 2:51PM with the following vacuum gauge readings, 1.6 x 10^-6 Diagnostics Box, 7.4 x 10^-7 Service Cap,
2.0 x 10^-6 Containment Box. Voltage was increased ~3kV at a time every minute until 21 kV was reached with a current of 0 uA. Voltage was then increased |

|
TM#1 with Nb#6 is now in the conditioning station. The fields of the module at the south cell was 15.8mSv/hr. The move was uneventful. Don Dale was present
for the move locking out parts of the code so only one movement of the crane could be done at a time. |

|
A HV test was complete on TM1 with Friedhelm, David, and Myself. The module behaved as it has in other tests. The vacuum achieved was 1.6 x 10^-6
in the diagnostics box, 2.3 x 10^-6 in the containment box, and 8.6 x 10^-7 in the service cap. Maximum voltage without continuous sparking achieved was
27kV. Current was unstable varrying from 40 to 300 uA. This voltage was held for 10 minutes. |

I did a helium pressure test on heat shield circuit. The leak detector is concected to the TM4 primary vacuum system.The IG1 is 1.1xe-6 torr,PNG4 is
1.5 x E-6torr,and IG4 is 2.1 XE-6torr.leak detector base leak rate:0.0xE-9 atm.cc/sec, base pressure is 0.0x E-4 torr.Applied 80psi helium to heat shield
circuit for 4 mins .There is no any response on leak detector during 4mins time. There is no pressure change during the test time. The heat shield circuit |

|
TM1 was moved from SHC to the TCS. The mode took roughly 1 hour. During the move the north east corner of the containment box caught slightly on the
flange of the vacuum vessel and then slipped off. The contact was minimal but should none the less be noted. After sliding off of the flange the module
did not crash into the other sides of the vacuum vessel, this is why I believe the contact was minimal. It should be noted that the corner of concern is |
