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. |
