Here is the analysis of the test runs with the 2nd DSSD (gen2) using the quick_si_plots.c script attached.
All 32 Si channels are working with acceptable performance.
In run001, there are some additional low energy peaks in nearly all x-strips, which I do not understand yet. They are around 3 MeV and are not visible in the y-strips. It doesn't look like an electronic problem, because there are at least 4
peaks, so not a low amplitude copy of the 3 major alpha peaks between 5 - 5.8 MeV.
However, in run002, the peaks have mostly disappeared, only in x6,x7,x8,x9 is a broad structure at somewhat similar energy... maybe this has to do with the small incident angle of the alphas?
Another run to confirm and double check this would be nice. |
