 Thu Feb 24 08:30:36 2022, JG, MS, AIDA5 calibration test failed - solved 
|
UPDATE: THE PROBLEM IS SOLVED FOR NOW:
Doing the calib for the 5th time eventually worked.

Thu Feb 24 09:43:16 2022, JG, MS, check 13x
|
Beam is still beeing tuned. Target is off.
- Motor on manual |

10.00 Outflow manifold returned from workshop with leaking attachment point welding re-worked.
11.30 Outflow hoses re-attached to outflow manifold. Faulty male Swagelok replaced.

Run 24 running
27/05/2025
We start a new run with real data taking condititon: beam is ok, target density is 5e11 cm-2, detectors are moving in-out periodically. |

Mon Feb 28 13:56:02 2022, JG, CB, Temperature cycle to 125K

Rutherford rate was decreased significantly for longer period.
Temperature increased to 125 K |

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. |

12:15 restarted measurement with target - Run 83
same settings as for runs 76, 77 etc

Mon Jun 2 20:03:43 2025, JG, AG, CB, EW, EM, Run 45/46, 0.5 MeV/A 13x
|
Run 45 started.
D+ beam deuterium target. D+ beam energy is 0.5 MeV/u. (beam calc calculation is 0.5143 MeV/u). See attachment for beamCalc
Target density is about 2e12 at/cm2 |
|
Mon Jun 2 17:25:31 2025, JG, AG, Run 43 scraper tests
|
Same settings are Run 42 but bunched beam and scrapers set to: 30 / - 30 mm.
|
|
Mon Jun 2 17:48:07 2025, JG, AG, Run 44 scraper tests
|
Same settings are Run 43 but with coasting beam and scrapers set to: 30 / - 30 mm.
all checks ok, but WR timestamp error, see attached |
|
Mon Feb 28 07:35:51 2022, JG, current logger crashed
|
The current logger did crash in the evening of 25.02. and stopped logging since then, it seems.
I restarted it now (28.02. 8:30).
Seems to run stable for now. |

Thu Feb 15 13:18:30 2024, JG, MBS DAQ: target & ring values
|
We are running an MBS DAQ to record the attached list of slow control values of the ring and the target. In most cases this is achieved by converting
analog monitor voltages to frequencies and recording them with a VME scaler (VULOM4B with scaler-firmware). The complete list of signals is attached including
a channel mapping. |

Mon May 12 13:25:09 2025, JG, MBS DAQ - overview
|
An MBS DAQ is running to collect two types of data:
1. WR timestamps for machine events (injection, target ON/OFF, ...)
