Removed thermocouples, heaters, RE72 modules and leftover baking tent. Support octagon removed except topmost part which requires disconnecting pneumatic
hoses going to top gate valve. To be done on Monday with ML assistance.
Attempted to move servo motors once more - did not work. The motors appear stuck but it is not clear how or where. Removed screws on flanged |

Wed Oct 6 15:36:14 2021, CB RSS, Neg activation tests -3
|
Attempted to activate 2xUHV1400 connected to bottom C4, channel #2 using P 200 W, t rise 30 min, t hold 90 min.
Temperature of Kapton bundle increased drastically to 160+ C. Had to stop. Conclusion is that these are likely
the two UHV1400 on the bottom of CARME, immediately in front of the Kapton bundle.

Ion pumps de-gassed by switching on and off multiple times. Large pressure increase the first time pumps were flashed, pressure recovers quickly
once pumps off. Subsequent flashing of ion pumps showed a significantly smaller pressure increase, unitl little increase was seen. |
