Counting Experiemnt

Discriminator setup for GEM and PMT's

The time period for counting 1 min.

GEM (amplified 15)


Voltage (V) Number of Counts (5min)
0.3 9 , 16, 26, 32, 46


Counting without a source (Background)

GEM and Sci. in coincidence (and gate), GEM oprating voltage is 2.7, 3.1V GEM and cathode successively, both of the PMT's has 1kV input voltage.
