 Tue Aug 31 18:34:41 2021, CB RSS + DR OG, CARME on Al stand 
|
Lifted CARME off the floor and mounted feet on sides. It was found impossible to put four bolts for each foot
due to alignment conflict. Three bolts were mounted per foot instead.

Wed Sep 22 14:44:51 2021, JM RSS ML, CARME leak test + bakeout tent
|
On 21/9/21 CARME was connected to the leak tester. Leak testing showed no apparent leaks, extra time required to reach <1e-4 mbar during initial turbo
pumpdown might be due to outgassing from additional installed components on the chamber. Turbo pump restarted
21/9/21 16:28 9.73e-7 mbar |

Mon Sep 20 11:45:45 2021, JM RSS ML, CARME installations 6x
|
Ion pump, RGA and additional gauge installed on the chamber.
Our gauge is the one mounted above the NEG feedthrough, Michael's gauge is mounted below the feedthrough. Ion pump too large to install on
the top of the vessel, sufficient room on flange immediately next to this top flange. |

Wed Apr 26 16:49:28 2023, CB, JM, CARME dolly mostly built
|
Disconnected cables from CARME motors and turbo. The turbo has to go to allow Carme to slide out. Crane may be required to lift because it's in a
very hard spot to access.

Sun Oct 31 08:05:15 2021, CB OH + DR ML, CARME closed again + feedthroughs labeled 11x
|
(Fri 29 October)
Cleaned wire seal recess and labeled thermocouples and flanges to identify p-n vs. n-n side and ports with bias pin. See attached in case baking
damages the label. |
|
Thu Jul 13 00:12:45 2023, JM, CB, CARME closed
|
The CARME chamber was closed and pushed back into position on the ring.
Prior to moving back onto the ring, the detectors were bias tested and the distance between the detectors was also checked using the motors.
Bias test was performed before the detector movement tests and before moving the chamber back onto the ring. |

CARME baking with heating tape continues
Left overnight at 100C. Turned up this morning at 9:00 to 120C.
All good except detector strain relief seems to be going much higher than detector (no obvious reason) and then cool down. Proximity to flange |

Thermocouple on CARME foot side (1-4) may have come loose judging from sudden jump in temperature at 14:30?
