Fixed, e793s, Wed Mar 17 19:19:05 2021, Franco, OFFLINE, General, CD2, Mugast 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. |

Fixed, e793s, Fri Mar 19 09:54:58 2021, 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. |

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.
