Entry  Tuesday, November 10, 2015, 10:23, Anders Mjos, Conditioning Station, Maintenance, TM3, , Air to vacuum leak on service cap TM3_Service_Cap_Leak.pdf

Conducted a more thorough leak check this morning with Edi. He found a leak on the base of the  blue F/T insulator for the multi-pin connector (see attachment). I discovered that all the bolts could rotate freely in the threads as they were too small. The bolts were replaced. The leak rate was reduced but still significant. The o-ring will likely need to be replaced.

Tuesday, November 10, 2015, 17:00: Could not find new o-ring. Cleaned groove and o-ring and applied o-ring grease. Re-attached F/T.

Entry  Tuesday, November 24, 2015, 13:54, chad fisher, South Hot-Cell, Repair, , , Cell Decon 

Decon/removal of large solid waste was performed on Wednesday November 18th."Hot" activated items included containment box cover from TM2, Febiad coil line remnants from TM4 (the hottest ends were previously cut off and disposed of), some target conductor bolts, steerer plugs from TM2, target material remn.

Drum containing these solid items is 2.5mSv/hr at 1/2m.

Drum is stored in the north hot cell temp.

Compressible waste will require another drum.

Swipes were taken of the window... 170k counts per minute of cont.

Entry  Tuesday, November 24, 2015, 14:00, chad fisher, South Hot-Cell, Repair, , , Compressible waste sorting. 20151124_101547.jpg

Residual fields from the remaining compressible waste were still too high (as far as I'm concerned) so I have unpacked all compressible waste looking for a "hot" item that has snuck into these items.

I have a hand full of small bolts (possible target components), a hand full of target material/dust (including an entire target disc), and some cloths that had clearly been used to wipe the table (they are black with target dust).

These items will be disposed of with the next spent target.

 It was found that the conversion from voltage to vacuum (Torr) in EPICS is not correct for the XGS-600 controllers in use at the TCS. EPICS did not correspond to local values displayed on the controller. An e-fault has been submitted.
