Thursday, April 23, 2015, 09:08, David Wang, Conditioning Station, Maintenance, TM1, UCx12, Huge Leak on TM1 contaiment box window.
|
There is a huge leak on TM1 containment box window. I did a 70 psi helium pressure test on all TM1 water circuits this morning. The LD base leak rate was 0.0XE-9 atm.cc/sec. When applying the 70 psi helium to containment box window circuit, the leak rate on LD jumped to 1XE-4 atm.cc/sec in 5 seconds.I released the helium source right away,t but the conditioning station is full of helium molecules already, and the leak rate on LD stays at 1xE-5 atm.cc /sec. The leak on this circuit is huge. Other water lines are good. |

Wednesday, April 22, 2015, 11:05, David Wang, Conditioning Station, Standard Operation, TM1, , electrical check on TM1 at CS under vacuum
|
I did an electrical check on TM1 at CS. The resistance check:A-B 3.918m ohm, A-C 5.905m ohm,A-D 4.070m ohm,B-C5.462m ohm,B-D3.633m ohm. They are very close to the check we did in SHC. The only unusual thing I found during the check is the ohmmeter reading between A and 60 KV common (6.2K )and the Megga reading between them at 250 V which is 0. I repeated 4 times and always got the same readings. However, after so many times check, the Megga reading between A and 60KV suddenly went back to normal(300 M at 250V) at the final check. And,it stays at 300M now. All other measurements are same as we did at SHC before. |

Tuesday, April 21, 2015, 17:14, Isaac Earle, South Hot-Cell, Standard Operation, TM1, UC#12, UC#12 Installed in TM1
|
On Friday April 17th, UC#12 target was installed in TM1. One of the copper water lines was bent slightly as the target was lifted into the module which caused ~15 minute delay due to difficulty getting the VCR nut threads to engage. Other than this the install went smoothly.
During replacement of the containment box panel two of the threaded holes were found to be stripped. One on the top at the center, the other in the bottom right corner. These two holes were left without fasteners (see attached photo). It is unknown at this time whether these holes were already stripped, or if they were stripped during this installation. |

Tuesday, April 21, 2015, 13:01, Grant Minor, ITW, Development, TM2, , TM2 MK4 Optics Tray - banana plug bore modification (on bench)
|
The MK4 optics tray prepared for TM2 (as per ITA6082) had an undersized bore for the banana plug, making insertion of the plug extremely difficult / impossible.
Reference stores parts were collected to check the fit: male plug 3-4/01152 and female jack 1-6/1201. The size of the female jack was checked with a #21 drill at .159".
The bore on the optics tray was drilled out dry using the #21 drill to the same depth as the original blind hole, by Maico and Dan McDonald. Chips were carefully collected in a rag, and the hole was blown out with compressed air.
The fit was checked to be snug but possible, using the male plug and the Remote Handling ultem base (ref ITA6023).
Redlines and photos are attached.

|
The TH will be locked during the TM1 conditioning time due to an interference issue between CS HV cover and a gas analysis valve on top of TM1. A work permit has been issued for the conditioning job because of it. |
