Fixede793s Wed Mar 17 19:19:05 2021 FrancoOFFLINEGeneralCD2Mugast detectors disaligned in Ex
The Ex distributions gated on the different MG detectors show large differences, up to 500 keV. In the attached figure I show as an example the comparison between two nearby detectors, MG3 and MG4.
I tried a rough alignment of the Ex by shifting it manually and setting the first main peak at Ex=0 (essentially taking MG5 as the reference, since his first peak is at 0).
These are the shifts applied:
MG1 -> -580 keV
MG2 -> -280 keV
MG3 -> -550 keV
MG4 -> -100 keV
MG5 -> 0 keV
MG7 -> -400 keV
The resulting Ex distribution is plotted in the second attachment, compared with the original below. The resolution of the first peak (assuming there's a single level there) is 420 keV FWHM.
I think it would be worth having the position of the MUGAST detectors re-measured.

Fixede793s Fri Mar 19 09:54:58 2021 Adrien, Freddy and FrancoGRITGeneral3-alphaAlpha 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.

Fixede793s Tue Mar 23 10:22:48 2021 Emmanuel COFFLINEGeneral Efficiency gamma AGATA --- real measurement run70

I have been working on the high energy response.
The point is that we do not have source measurement beyond 2 MeV to constrain the fit.
In the attached file, the experimental points are the measured from run 70 in 152Eu source. The fit is then extrapolated up to high energy.
I have simulated the efficiency at 3.5 MeV in GEANT4 including real geometry, missing channels, unefficiency of capsules etc.... The overall agreement was checked on the 1408 line. The 3.5 MeV simulated point is shown. It disagrees strongly with the extrapolation. The blue fit includes the simulated point. It doesn't change the efficiency evaluation < 1.5 MeV but correct the high energy response.

Pinnede786s Wed Apr 10 13:30:48 2019 Valerian, Adrien and Antoine (edit by Louis)OFFLINESoftwareN/AHow to perform analysis for e786s

Here is the updated procedure to convert a run, with VAMOS data and add those data to the Kinematic plot.


Every 4Go there will be a file change, to see if there is a file change do :

  • ls -ltrh /data/mugastX/e786s/acquisition/run/

convert the last 4Go file and add it to the chain using the following step:

Step O: Take your favorite ortholinear keyboard (optional)

Step 1: Login the VAMOS environment and convert the run :

Open a terminal from one of the mugast computer:
  • Type: source $HOME/GoToVamosAna
  • Type: MyVAna -d2Ar -f /data/mugastX/e786s/acquisition/run/run_$$$$-DD-MM-YY.HHhMMmSSs /data/mugastX/e786s/acquisition/RootA/r$$$$_000a.root
OR
  • Type: MyVAna -d2Ar -f /data/mugastX/e786s/acquisition/run/run_$$$$-DD-MM-YY.HHhMMmSSs.N /data/mugastX/e786s/acquisition/RootA/r$$$$_00Na.root
(If you encounter the error on Brho "Could not find the BrhoRef for the run <RunNr> ", Update the ./Calibs/ListBrho.dat file with relevant Brho for RunNr)

Step 2: Analyse the file using the npanalysis program:
  • Type: exit (<-this exit the environment of VAMOS)
  • Type: lpcgrit (<-this load the analysis environment )
  • Type: npp MUGAST
  • Type: edit the exe.sh to treat releverant run. command should be: npanalysis -D mugast.detector -C Calibration.txt -E ./Reaction/46Ar3Hed.reaction -T ./offline/root_e786svamos/r$$$$_00Na.root AD -O run_$$$$_N.root

(This could be used with any file, either from Offline conversion, or the VAMOS Analysis conversion or the Merged Tree from AGATA)

The run will be created in the NPOutputs folder
Fixede786s Fri May 31 09:53:14 2019 MarlèneGRITGeneral 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.
Fixede786s Mon Jun 3 18:00:10 2019 MarlèneGRITGeneral MUGAST detectors status --> MG4T
The problem of MG4T ha sbeen solved by changing the feedthrough.
The pulser on Y was not working and we were seeing no events (no ORD) because there was a problem with the bias of board. The issue is due to the feedthrough.
So now MG4T (HT &BT) are plugged in a free feedthrough (below MG1T) and I see pulser signals on Y.

The bias seems to apply normally on all detectors (in the dark).
The pulser is seen on each boards.
I have put back aluminium foil on square but I could not test it.
