 Fri Jan 16 13:59:08 2026, JM, [How to] Startup CARME via x2go
|
The startup procedure is the same as the regular startup as described in elog https://elog.ph.ed.ac.uk/CARME/666 with some important differences
x2go opens up the computer on the GSI network carme@atppc025
In order to access the carme computer and the CRYRING network we need to ssh. |

Fri Jan 16 13:54:08 2026, JM, Background run - R6/7
|
12:00
Background run started via x2go - Run 6
We need to run for a while to gather sufficient stats on aida05, aida06, aida07 and aida08 channels to see which capacitance is best for the |
Wed Jan 14 09:06:01 2026, EW, JM, Jan26 - electronic tests 7x
|
R3 pulser walkthrough completed.
Pulser amplitudes from 90,000 to 10,000 in steps of 10,000
Pulser peaks widths taken again. Some channels show big improvement. Note leakage currents are higher today. See previos elog |

Tue Jan 13 12:59:37 2026, JM, EW, CARME startup - Jan26 tests 12x
|
13/01/26
Arrived at GSI.
Biased DSSDs. Noticed higher leakage currents than previous experiment circa 19uA for DSSD#1 and #3 and 9uA for DSSD#2 and #4 |

Thu Dec 18 16:30:49 2025, CB, ML, JM, Attempting to start CARME background
|
ML flicked switch on CAEN bias module to Enable, and restored remote control.
Attempted to bias the DSSDs. Leakage currents significantly higher than before, but apparently stable. See attach 1.
Likely a vacuum gauge turned on? Will have to investigate. |
|
Tue Aug 26 14:43:44 2025, JM, CB, EW, CARME on, background run
|
26 August
14:40
Turned CARME on |
|
Thu Jul 17 07:07:56 2025, CB, CARME off
|
08:07 CEST
Temperatures ok - attached
DSSDs on. Leakage currents still high. - attached |
|
Wed Jul 9 11:21:14 2025, EW, CB, CARME restarted - long background R98 32x
|
---9 July---
11:00
Turned detectors on - all stable see attachment 1 |
|
Sun Jul 6 11:35:28 2025, CB, Anydesk version updated
|
Updated anydesk to 6.3.2 CentOS7 release.
Works now. |
|
Sat Jul 5 08:51:33 2025, EBM, anydesk connection settings
|
| |
|
Wed Jun 18 14:21:39 2025, CB, CARME off
|
15:20
DAQ stopped
Merger & Tape Server stopped |
|
Tue Jun 17 23:51:58 2025, TD, CB, JG, Run 96 - continued 23x
|
00.31 DAQ continues data file G22-205/R96_27
|
|
Tue Jun 17 19:10:07 2025, NH, PMH, Run 96 7x
|
20:00 - Go to YR cave to see what is going on
20:20 - Beam back
|
|
Tue Jun 17 12:22:50 2025, CB EW JG AG SN, Run 94/95/96
|
Run 94
Background with beam at 150 keV and no target.
Note energy is 0.15% off vs. beam and target to have a more realistic orbit. |
|
Tue Jun 17 12:14:30 2025, EW, CB, AG, Run 93- Background with beam 150keV
|
Run 93- New run at 150keV, background with beam
13:15 All checks ok |
|
Tue Jun 17 08:04:09 2025, EW, AG, CB, Run 92- Background with beam 90keV
|
Run 92- started at 09:00, background with beam
Same settings as run 91
See attachments for rates etc |
|
Mon Jun 16 22:06:00 2025, CB, AR, EW, RUN 90-91 14x
|
23:00 DAQ restored and data now being written okay. Checks all okay, see screenshots below. Histograms reset. 40 bars in bottle @ 23:45 - should last
30 hours.
12:00 Checks all ok. No problems with aidas or writing to disk. |
|
Mon Jun 16 21:58:00 2025, CB AR, Runs 84-89
|
Found all Merger Links background black - inactive. Nontheless the tapeservice was working, the data rate to disk was normal, and the file was being
written and the histograms were being updated.
Decided to stop DAQ, stop Merger, restart merger. Links rest to green background - but no more writing to disk! |
|
Mon Jun 16 11:12:22 2025, JG, AK, AR, EH, run 83 8x
|
12:15 restarted measurement with target - Run 83
same settings as for runs 76, 77 etc
ROOT histograms NOT zeroed |
|
Mon Jun 16 10:46:11 2025, CB JM JG AK, Run82
|
| Background without beam while source is optimised. |
