Freddy | S1 | Hardware | N/A | Annular degradation |
I posted a detailed entry during the night about the evolution of the annular detector but it was deleted somehow...
Signals on 3-4 segments were entirely lost between run 139 and 140. It creates a lot of holes on the impact matrix.
An increase of leakage current from 0.2 to 1.4uA occurred at about the same moment:
*Wed Jul 24 21:44:44 2019 --> 0.2 uA
*Thu Jul 25 06:53:15 2019 --> 0.6 uA
*Thu Jul 25 13:23:48 2019 --> 1.4 uA
*Thu Jul 25 22:25:35 2019 --> 1.3 uA
*Fri Jul 26 07:26:23 2019 --> 1.9 uA
Screenshots about this issues are in the e768s screenshot folder.
Edit : Adding some related files from the folder, not sure if the good ones (Sylvain) |

Franco | OFFLINE | General | CD2 | Angular distributions |
- Updated the macro for the angular distributions.
- For the angular distribution of the peak at 4 MeV excitation energy I think we need the calculation for the transfer 0f5/2.
- Added the gamma spectra gated on the 3 main peaks in Ex in the macro DrawPlots.C (arrows and labels of the gamma should be added). |

Marlène | GRIT | General | | Alpha source --> status of detectors |
MG3T has been fixed by changing the X kapton.
I have removed aluminium foil on square detectors, the noise is slightly higher.
MG4T is not working properly : noisy on X but no signal on Y !! I see no triggers on the Y side. I tried to increase bias but it did increase noise. I checked in the last calibration of e744 it was working properly. Also I had to do pedestal realignement for this detector because everything was shifted.
MG7T seem to be slightly different than before. Strips X are hidden from the trigger because it became suddenly noisy. |

Adrien, Freddy and Franco | GRIT | General | 3-alpha | Alpha calibration and noise on MG3 and MG4 after the experiment |
While starting the alpha source runs after the experiment we found unexpected noise on MG3 and MG4 which cannot be excluded just by masking some Y mates (The X mates were already masked for both of them). We cannot figure out the origin of this noise.
Run 652 and 653 -> alpha runs without pedestal suppression
Run 655 -> alpha run during the night with pedestal suppression. Here MG3 and MG4 are not in the trigger.
Run 658 -> alpha run after an attempt to mask some noisy strips. The number of ORD is anyway high (some 10^4) but we see some alphas on MG3 and MG4.
Run 660 -> same as 658 but with higher thresholds on X (8250) and Y (7600 on MG3 and 7950 on MG4) to write less on disk but actually nothing changes. Therefore we are writing about 2.7 GB per hour.
The other runs (654, 656, 657 and 659) can be discarded. |

mugast | GRIT | General | 3-alpha | Alpha calibration - run 600 |
After 2h30' of run we checked the temperatures of the boards and we noticed that MG7 had 63 degrees on both X and Y, which is very high; MG9 was around 56 on X and 26 on Y. There might be a problem in the loop of the cooling system because the other detectors are pretty fine, with temperatures around 20-25 degrees.
In attachment the evolution of the (calibrated) DSSD energy for MG7 during the run.

Beyhan, François | OTHER | General | | Alarm in G2 but no beam stop |

Beyhan | OTHER | General | | Alarm in G2 |
Alarm signal from G2.
No beam since 20:30
PCP will have a look in G2, following the procedures.
We do not stop the run for the moment.
20h50 The alarm is given from the captor on the top of the liquid nitrogen dewar of exogam.
It has most probably being set during the detectors filling.
beam back at 20:59 |

Nicolas | OTHER | General | | AGATA: what if a crystal status get red |
1. Go to the AGATA Digitizer: Control tab of the browser
2. Select the detector and crystal, then click 'Select'
3. Click the 'ReSync Current Digitizer Optical Link'
Normally it should go green again, otherwise call AGATA people |

Nicolas | OTHER | General | | AGATA: replaying runs |
1. Go to the AGATA analysis computer, open a terminal and execute the following commands:
> a4
> t e768s
> cd Replay
> ./do_global_replay.sh -run ### (### is the run number you want to convert)
if it complains that the folder with the run already exists, just > rm -rf runXXXX/ (where XXXX is the run you're replaying) in the Replay folder
2. When it is finished copy the root file to the GANIL world:
> mkdir /dataganil/e768s/acquisition/root_agata/run_0###
> cp ./run_0###/Out/Analysis/Tree_00*.root /dataganil/e768s/acquisition/run_0### |

Freddy | AGATA | General | N/A | AGATA validation problem (solved) |
Since about 4h20, we realized that AGATA validated events and timestamps have suddenly dropped on the AGATA display (yellow bars instead of green).
We checked the counting rate on MUGAST, VAMOS and FAG and there is no obvious problem on this side. Same for the MUGAST/VAMOS data on disk.
We call Emmanuel...
Problem solved by restarting entirely GTS Tree (that was broken).
Restarted at 5h37 with run 59. (it took about 30 min). |
