|
TM#4 with SiC#26 HP has been checked electrically it has passed. It was noted that the Megger check of the Oven to Chassis (earth ground) and Oven to
60kV Common is low but will not hinder running, according to Don Jackson. Also yesterday the transition piece that sits on the 55 pin connector was
damaged from excessive handling, it was removed and repaired and it now back in place. |

Thursday, September 01, 2011, 09:11, Don Jackson, ITW, Standard Operation, TM1, UCx#2, Argon Venting West Station
|
West target station is setup to use argon for tank venting. There is 1200 PSI remaining on argon bottle in electrical room. That is sufficent
for venting west target station to atmosphere twice. ISAC Operations has been previousily contacted and their procedures for venting remain the same
except that they can not rely on ITW:CG4S to determine when at atmospheric pressure. I have asked them to contact me if an unscheduled vent is required. |

|
Today a leak check on TM1's external seals and the heat shield line was completed by David Wang. After 16 hours of the turbo pumps running on the conditioning
station stations pressures were 3.6 x 10^-6 T, 1.2 x 10^-5 T, and 1.8 x 10^-6 T for the containment box, secondary vacuum, and service cap respectively.
This is a significantly quicker pump down after the cross with small turbo pump was installed on the vacuum vessel. The base pressure of the leak testing |

|
On August 22nd TM1 was vented with Argon in the conditioning station. It had been pumping with just the roughing pump over the weekend so the UCx#2
target would not be exposed to oxygen. The move went without incident and took roughly an hour to complete. Once at the hot cell the panel was removed
by Tom Lyth and a leak check completed with Bevan, David Wong, Grant Minor, and Tom Lyth present. The connections to source tray were checked starting |

|
A leak check was performed on the module when it was in the conditioning station today. There were no external leaks
found. When the coolant lines were check a small leak was found in the heat shield circuit. Base leak rate was 6.7 x 10^-9 atm cc /sec and rose to 4.1
x 10^-9 atm cc /sec quickly (~3 seconds) and remained there for the 2 minute test. The remaining lines |

|
Pump down in the conditioning station started at ~2:40 for rough down. The turbo pumps were turned on at ~3:30 and at 3:52 the pressures were reading
as follows:
IMG in the containment box 9.2 x 10^-5 T |

Thursday, August 18, 2011, 14:09, Bevan Moss, South Hot-Cell, Standard Operation, TM1, UCx#2, Leak and Electrical Check plus Remote Move to Conditioning Station
|
TM1 with UC#2 had the target installed, the heat shield line was pumped on and achieved a vacuum of 0.0 x 10^-4 Torr and a leak rate of 0.0
x 10^-9 atm cc / sec with no response when sprayed with helium. An electrical check was completed by David and myself all values were withing tolerance.
The module was then moved from the south hot cell to the conditioning station where it will start pump down. The move was uneventful every operated |

|
UCx #2 has been installed onto TM1.
Installation went well except the left leg got bent slightly sometime between testing on the jig and installation onto the module (probably
during removal for the argon filled bag). Leg was gentle offered into place and its clearance with the heat shield double checked with both a mirror |

Wednesday, August 17, 2011, 13:09, Bevan Moss, ITW, Standard Operation, TM1, Ta #37, TM1 move from ITW to Hot Cell
|
TM1 with Ta #37 target was moved from ITW to the south hot cell. The rotation of TM1 may have been off slightly during the final removal from ITW
but it was minimal. Entry into the south hot cell went with out incident. This was my first time moving the module without the presence of Travis Cave. |
