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 |

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 |

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 |

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. |
|
Tuesday, April 28, 2015, 11:09, Anders Mjos, ITW, Maintenance, , , Resistance measured of TGHT and TBHT lines to ITW
|
The new TBHT and TGHT power supplies were brough up to high current; 350 A and 420 A respectively. The TGHT power supply was limited by PLC to 420 A.
The resistance calculated for both the TBHT and TGHT copper lines from the electrical services room to the ITW pit was 1.35 mOhm. See attached spreadsheet
for details. |

The schedule has some changes due to new TM2 source tray coil cooling line leaking at test stand. Now,It is re-scheduled in such an estimation
that TM2 source tray could be ready at teat stand by this Friday(May-15th). see attachment 1,2.

Wednesday, May 13, 2015, 13:55, chad fisher, South Hot-Cell, Repair, TM2, , Shutter removal
|
TM2 has been successfully de-shuttered.
All went pretty much according to plan except I had to remove one fastener out of the upper wiring harness (the one that has just been installed)
to allow for enough clearance to rotated the shutter guide out of the way...I shutter to think what would have happened otherwise...anyways... |
