 Tuesday, June 16, 2015, 14:28, chad fisher, South Hot-Cell, Repair, TM2, , TM2 Source Tray Installation/Water Block Sealing Surface Clean 
|
Today cleaning and polishing pads were inserted into the hot cell.
Module side waterblock jig installation was attempted however one of the locking tabs/latches (ITA2405?) came undone/fell off. Luckily, I had old,
obsolete jigs in the hot cell so I was able to remove parts I needed from an old one and rebuild the current one. |

|
TM2 new source tray has been remotely transferred into SHC successfully. The transfer table has been moved back to TH within 1 hour. I swiped the
table and found about 150counts contamination. It is much better comparing to last time using since we removed this table out of SHC as quick as we can.
The table will be cleaned with windex after Target Hall is surveyed. |
