EMERGENCY SHUTDOWNS
1. CARME motors: Q key on keyboard while on workspace 1 of appc218 (right of this double-monitor setup)
2. Internal target: Q on keyboard while on workspace 3 of appc218, go to server room, press "CLOSE" button on DUMP. |

Tue Feb 22 12:23:23 2022, CB, Slow comparator thresholds lowered - test run
|
13:20 Stopped run.
Slow comp thresh 0x64 -> 0x32 on all FEEs
Checkload x2 |

Fri Feb 25 11:20:30 2022, CB, Pressure and temperature data saved
|
Saved pressure reading and temperature data logs from internal target in /TapeServer/22Feb/OtherData
Leakage current data is saved in /home/npg/Programs/caenlogger

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. |
|
Thu Aug 31 08:36:34 2023, CB, NEG activation
|
Found CARME at 50C, a bit cooler than expected, probably due to invasive tent changes yesterday to mount missing wires. Increased heaters temperature
to 300C
|
|
Fri Sep 1 08:11:40 2023, CB, NEG activation - 2
|
9:10 Set heaters temperature 300 -> 250 C in preparation for cooling down and to help keep DSSD temperature down. Started activating set 6 (3 X DSSD)
at 120 W as per previous procedure.
9:15 Realised previous choice is a mistake in the current configuration as the DSSD TC is closer to set 5. Set 6 off. Set 5 to 60W. No effects |
|
Sat Sep 2 10:04:55 2023, CB, Turbo GV closed
|
Found CARME in XHV at 1.1E-11 mbar. Chamber temperature around 30C cooling slowly.
Closed GV to top turbo. Pressure goes up but appears to recover around 2.5E-11 mbar, on line with several previous observations that sectioning
off the turbo results in a higher reading in the IE514. |
|
Sun Oct 15 09:35:03 2023, CB, Starting ramp down
|
10:40 - Status as attached. Heaters setpoint/read at 250 C, 150 C, 225 C. Power stable at 53%, 41%, 63%
10:45 - Informed HKR ramp down / pump activation is starting for CARME only. Setpoints to 200, 125, 200 C. Monitoring slow ramp down.
14:10 - Heater temperatures reached the set points. Power stabilising. CARME internals temperature dropped to around 100 C and still falling. |
|
Mon Oct 16 08:28:02 2023, CB, NEG activation -1
|
9:00 - Michael's online vacuum pressure plot is no longer working - an old image is being displayed. CARME temperatures around 80-85C. Lowered heater
temperatures to 150, 100, 150 C for safety. Lowered jacket temperature to 80C
9:15 - Flashed ion pumps several times. Small pressure increase, up to ~7E-9 but not macroscopic |
|
Tue Oct 17 08:43:47 2023, CB, NEG activation -2
|
09:40 - Found temperature and pressure stablised, but too high to comfortably activate NEGs closest to detectors. Detector temperature around 90C. This
was expected. Ramped down UHV1400 #1,2,3,4 to P=50W (200C?). Ramped down heaters to 100, 80, 100C. Ramped down heating jacket to 60C.
10:00 - Activated set #5 (x2) at 80W tramp=30, thold=infinity; set#6 (x3) at 120W rest as #5. This is different from previous procedure because |

Tue Feb 6 09:39:54 2024, CB, Detector bias tests 13x
|
10:30 Found ADC#4 on aida 1 and 4 are suddenly noisy. See attach 1-2. Checkloaded multiple times - no effect.
Leakage current overnight was stable, but a clear transient can be observed yesterday around the times of the DSSD motion test. We did not observe
this in the cave looking at the CAEN module - it might have been too fast. |

Fri Jun 7 10:05:40 2024, CB, Run 41/42/43 - 15N data taking start 8x
|
11:05
Confirmed overlap is at 4 mm under new settings.
For unclear reasons, the bottom-left detector is not seeing the halo anymore since around 10:00. Rutherford still visible and if the left arm |
|
Sat Jun 8 06:13:21 2024, CB, Run 47/48/49 - target issues & tests
|
07:00
After putting the target back, we observe strong periodic (5 s) fluctuations going from 3E11 to 5E12. The reason is unclear. One may warm up
the target to solve this, but will ask Nikos later instead. |

Mon Jun 17 23:10:08 2024, CB, Run 90

As run 89, detectors moved fully out.

Moved the detectors back to the usual configuration (as per run 89).
Moved target away - background run. |

Sun Apr 20 07:30:29 2025, CB, DSSD leakage currents over Easter
|
Just after midnight on 20/04 it appears DSSD #4 leakage current has perfectly stabilised. See attached.
DSSDs remain biased.

Sat Apr 26 22:01:37 2025, CB, Proxy bridge

Proxy bridge enabling anydesk and generic Internet access dropped due to atppc025 being rebooted. Found it dropped again late today.
Restarted bridge inside a screen session. |
