Run 1
GEM Backgrnd.mpa
GEM HV : VDrif = 3850, VGem = 3550
HRRL : E = 14 MeV, I =0
5 minutes long
Run 2
Run2.mpa
GEM HV : VDrif = 3850, VGem = 3550
HRRL : E = 14 MeV, I =20mA
ADC 1D has clear second peak at channel 150 but ADC1 does not. Lets Observe ADC 1D as a runction of position. This corresponds to GEM output strip 13.
5 minutes long
