RUN 96

double alpha source
MG1
MG3
MG4
MG5

MG7
-
-
MG11

MM1
MM2
MM3
MM4

Missing strips in Y the same as in run 40

Problem with the annular MG11 -> no current when bias is put... --> to be checked

Problem with the insertion of the target holder --> solved

I also checked again MG9 (still noisy)
and MG10 with 140V I=0,52uA and counting rate is the same order of magnitude as trapezoid. Spectra are OK (not saved).
