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 <math>\frac{gamma}{neutrons}</math> 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 <math> \frac{gamma}{neutrons} </math> gives 6.03
