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:

|
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 |

|
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. |

|
TM1 has received the Ta#37-LP and has been pumping since thursday. This morning the pressure gauges read, IMG1: 1.6x10^-6 T and IG1: 7.4x10^-7
T.
The high voltage power supply has been connected to all high voltage feedthroughs and the voltage raise to 42 kV. |

|
Ta#35, in pail #88, has been place into spent target storage, in spot 6C. Upon removal from the South Hot Cell it was 411mSv/hr our hottest target to
be placed into storage to date. There are 8 free slots for targets left in the vault. |

Over the period of July 20-21st TM1 had several repairs completed and tested. The easiest of the repairs was the installation
of a gasket and a blank off. The next repair was to replace the 2 oring on the side panels that were removed for inspection and repair. The instrument
panel oring was replaced again and the previous one measured. Both were found to have the correct diameter of 0.131 inches for the seal groove. When attempting |

Tm4 w/ Ta#36 has been vacuum leak checked using the standard leak check procedure.
At 1:45pm RH was contacted to notify them that TM4 is ready to move. |

Ta#36 has been installed on TM4 and is awaiting leak and electrical check.
A small piece of the standard top insulator ITA3376 broke off during removal of Ta#35 (indicated with a blue circle on attached pictures).
"JP's connector, ITA2493 showed the usual and as yet undiagnosed "arc" mark (picture to follow). |
