Monday, April 27, 2015, 17:09, Grant Minor, ITE, Development, TM2, , TM2 - New Source Tray - Water Block Seal Groove Inspection Report 
|
The water blocks soldered to the TM2 cooling lines (see Ref. Assy. ITA6144) were inspected.
See attached inspection reports and drawings.
It was found that only 18% of the seal groove diameters and 55% of the depths were in spec. |

Monday, April 27, 2015, 16:12, Keith C Ng, South Hot-Cell, Development, TM2, , Ceramic Standoffs in TM2 source tray steerer assembly
|
On drawing ITA6008 for the Encole 0.5" ceramic standoffs there is a note to match pairs of ceramics to within +/-0.001". This step was missed
on the current build of TM2 source tray (ceramics were not measured).
Measured the lengths of the rest of the ceramic standoffs in inventory and they range from 0.5035" to 0.4950" in length. The ceramics |

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 |

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 |

|
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 |

|
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 |

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. |

See attachments 1, 2 for target hall schedule from 07 April to 26 June 2015. The first TM1 move which is scheduled on 16 April 2015 could be delayed
because of SHC operator availability. I will update the schedule once Don confirms the move date with Isaac.
Updated the schedule. The TM1 move has been re-scheduled to Friday, 17 April 2015. See attachments 3,4. |
