 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.

Thu Oct 7 08:40:09 2021, CB RSS, CARME in XHV
|
CARME reached 9E-12 this morning
Ion pumps on
|
Fri Oct 8 17:56:35 2021, CB RSS, Motors test 
|
Attempted first motor test in XHV. Wired and connected limit switches and string potentiometer.
Set up raspberry pi to control motors (.124). Set up pi for remote headless access.
Moved jumper on Teknic hub from 1 to 2 motors configuration. |
|
Sat Oct 9 09:44:36 2021, CB RSS, Heaters removed + motors tests
|
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 |
|
Sat Nov 6 14:21:10 2021, CB RSS, Preparation for bakeout tent mounting + to do for next week
|
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 |

Tue Nov 16 12:05:13 2021, CB RSS, CARME baking with tape continues
|
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 |
|
Thu Nov 18 12:29:50 2021, CB RSS, Conditioning D2000 NEGs
|
D2000 thermocouples report temperatures around 100C (D2000 #1,2) and 120C (3,4). 1,2 are in the intermediate chamber, 3,4 are behind the moving arms.
3 is directly being the detectors.
Wanted to flash ion elements in D2000, but SAES recommend >100C to flash. |
|
Thu Nov 18 13:50:51 2021, CB RSS, Thermocamera images 14x
|
Used thermocamera provided by GSI beam diagnostic division to take some pictures of YR09. See attached.
Due to aluminium outer wrapping some reflections are inevitable, but tried to only take pictures of heat spots that did not disapper from different
angles. |
|
Fri Nov 19 12:03:51 2021, CB RSS, Conditionings NEGs
|
Increased conditioning temperature in D2000 #3 and 4 (behind detectors) to 150C from 130/140C. No appreciable change in temperature. Minor effects in
pressure.
Pressure has completely recovered from yesterday and did not settle on higher/lower plateau value which may suggest conditioning the D2000 NEG |

Sun Jun 9 13:45:24 2024, CB PMH AG, Run 55 - Data taking 18x
|
14:45
New run 55 with:
Right arm at 64.60 mm |
|
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. |
|
Sun Oct 31 13:55:13 2021, CB OH, Leak tests
|
Found CARME at 2E-7.
Closed valve on top of roughing pump. Clamp was not tight. Pressure still good.
|
|
Fri Jun 14 14:48:02 2024, CB NP ML, [How To] Change target pressure. EMERGENCY ONLY!
|
ONLY FOLLOW THESE INSTRUCTIONS if E1 turbo is below 820 Hz, pressure in E1 is above 2.5E-1 mbar and experts (Nikos, Andreas) cannot be reached.
Go to the red cabinet under the stairs. |

Tue Sep 7 12:40:43 2021, CB ML + RH, CARME survey preparation
|
Rudi and survey group representative came
to CARME.
|
|
Mon Sep 6 14:13:17 2021, CB ML, Motors mounted - first attempt
|
Mounted both motors on CARME. Started
with outside motor.

Thu May 29 14:39:52 2025, CB LB PMH, Run 31 9x
|
15:40
Waiting for Serge to come in to change beam energy.
Remaining at the same beam energy and settings as before, except RIGHT arm now moving. |
|
Fri May 30 07:27:41 2025, CB LB JM NP EM, Waiting for deuterium 8x
|
08:27
No run going.
Temperatures OK - attach |

Sun Oct 31 07:21:09 2021, CB JM RSS, Detectors arrived in GSI 6x
|
(Tue 26 October)
Two new CARME DSSD arrived in GSI and collected. Visually inspected both sides. No obvious damage. Photos attached. Second detector (3335-2)
was shipped in upside-down box. Does not seem to have made any difference. |

|
Fri Oct 29 15:09:27 2021, CB JM + RSS OG DR, Preparation to mount new DSSDs 6x
|
(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 |
