|
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 |

|
Chad and I did a leak check on heat shield circuit after target is installed on TM1.The leak detector pumping down is smooth. The base leak rate is 0.0xE-9
atm.cc/sec. The base pressure is 0.0xE-4torr. Chad checked helium flow downstairs and sprayed helium to each joints for 2 seconds.The first joints is good
and there is no any response on leak detector.we double checked it again and got the same result. On the second joint, Chad sprayed helium 2second. After |

|
Nb#6 was removed from TM1...it looked very clean.
Ta#38 was installed onto TM1...fit well.
Isaac Earle did this change with supervision in an effort to cross train. |

Wednesday, June 06, 2012, 08:21, David Wang, ITW, Standard Operation, TM1, , TM1 disconnected in ITW
|
I disconnected TM1 in ITW yesterday morning.The general radioactive level in ITW over the TM top (300mm) is about 350 usv/hr. contacting level on TP1
and TP2 are 1.0-1.2 msv/hr. I took 0.22 msv dose .The module is moved to
south hot cell later and a shielding plug is put back to ITW. Everything is fine. |

Tuesday, June 05, 2012, 15:06, Bevan Moss, ITW, Standard Operation, TM1, Nb#6, Module move from ITW to SHC
|
TM1 has been moved from ITW to the SHC. The move did encounter some issues, one of the railings for preventing people from falling into the MAA
was hit with the containment box. This caused the module to rotate. The module rotated ~90 degrees before the problem was noticed. The module was backed
off from the post once noticed but had already freely rotated. The box was inspected with the cameras prior to being inserted into the SHC. No damage was |

|
5 shielding blocks have been transferred from ITW to ITE. ITE ventilation is opened, and ITW closed. All ITE water signals have been
checked for frequency and strength.They are all good. ITE is ready for taking proton beam. |

Five targets were moved to the mini storage today in preparation for transfer of the targets to the F308s later next week. The moves went well. See the
attached files for the vault and mini storage details. |

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 |

Chad and I leak checked the heat shield circuit after sic 27 target installed. It took 20minutes to pump down the circuit to the leak
detector bottom scales. The leak detector is calibrated today,and all the vacuum lines and connections are leak checked by spraying helium. Chad sprayed
helium to each vc fittings for 2 seconds. There is no any response on leak detector . The test repeated one time and the result is same. Chad flushed |

SiC#26 was removed from target module #4 this morning. Target shows the now standard arc marks on the 9 pin connector housing...pictures to follow.
Of greater concern is the amount of "plating out" or "arc" marks on both the insulators and connductor of the TM4 source tray.
I will again warn that the source trays historically have a life expectancy, and that TM4 continues to show visual signs that the current |
