With the assistance of Oemer and Davide all of the M22 bolts removed from the downstream section of the CARME chamber. To separate the downstream section
from the
upstream sections it was necessary to use a lever between M10 bolts screwed into the lift points of adjacent sections of the CARME. The upstream sections |

Neg and ion cables were taken off and were put in the box.
Top support was taken off.
Motors are rotating again. Have to be careful with the position of the limit switches. |

Split funnels were given to Oemer for cleaning. Have received them back after lunch.
Valve support is installed again (see picture 1).
Ion pump was connected but not activated. Michael will help in doing so. No vacuum support to help will RGA. Will proceed without it. |

0. Give split-funnels to OG or Grossmontage to clean. Mount back foot support for gate valves. Critical when we split.
1. Wait for vacuum division to come to install: IE514 cables to current CM52 module, ion pump cables + controls + turn on, RGA head + program
+ turn on |

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 |

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. |
