Detector A: High Voltage = 1900V; Threshold = 5mV
Detector C: High Voltage = 1860V; Threshold = 10mV
Detector D: High Voltage = 1950V; Threshold = 5mV
Note: Really high background in the experimental cell, so more shielding was added: i.e. paraffin wax.
Experimental cell setup after adding addition shielding:
Graph before shielding:
The number of counts for the gamma flash (Channels 2000-2500) = 818
The number of counts for the neutrons (Channels 2500-4096) = 256
Taking the ratio
gives 3.19
Graph after shielding:
The number of counts for the gamma flash (Channels 2000-2500) = 1127
The number of counts for the neutrons (Channels 2500-4096) = 187
Taking the ratio
gives 6.03
