Pressure found in 10-7 mbar range.
Decided to leak test anyway for safety.

Removed turbo pump and set aside in a box. Considering switching to the other turbo to avoid degradation due to lack of use.
Installed bellows support and OG devised support to avoid bellows sagging when Carme is split open. |

Wed Aug 30 10:28:36 2023, CB, Preparing for pumps on
|
We need to connect the non-bakeable (max 80C) wire of the ion pump belonging to the vacuum division, and we also need to connect the two newly-repaired
NEG cables to the D2000 modules. That requires partly opening the tent to gain access.
Set heaters temperature from 450 C -> 400 C - CARME floating TC temperature goes from ~98 C to ~88C. |

(Mon 25 October - Tue 26 October)
Considered different strategies to mount DSSDs inside CARME, while waiting for 2x new DSSD to arrive.
Plan A: Mount DSSDs on plate on the bench, slide plate on rod, then attach cables, then attach strain relief |

|
Connected pneumatic hoses prepared by Gleb. Opened flow to pressure reducer set at 2 bar. Ok. Attempted to operate pneumatic motors. Somehow left / right
pneumatic motors controls swapped around! Works fine otherwise. Most likely hardware issue, i.e. hoses are inverted inside motor box. Software fix possible
in principle. Probably easiest to swap hoses going out from motor box (top to bottom and vice versa). Could not pull out hoses after installing. To do |

Mon Apr 24 21:24:26 2023, JM, Preparation for CARME dismount
|
CARME currently in vacuum, pressure ~3E-10 mbar. Chamber to be vented tomorrow afternoon by vacuum division. We have active both pirani and hot cathode
gauge to aid.
Equipment removed from the chamber in preparation for dismount of CARME from the ring this week. Equipment removed includes: |

Wed Oct 18 16:47:36 2023, JG, CB, Power outage
|
Local power outage at the CRYRING today, while JG was trying to activate the ion pumps. Unlcear what caused it.
Valve on scroll worked as intended, but CARME reacehd 1E-7 mbar from turbo (?) venting.
Power restored. Pressure back in the 1E-11 mbar range, decreasing. |

| ML reports power cut in CRYRING cave. Reasons unknown. No effect on vacuum, but top valve closed for safety reason. Ramping down temperature. |

Wed Sep 29 09:27:38 2021, CB (remotely), RSS JM ML, Power cut
|
Sudden and unexpected power cut at 10:02 German time, affecting all the target hall.
It has been caused by the emergency alarm being triggered. Reasons unclear. Electricians were informed.
