- Condition of above results
Shutter is Open
Red is Cf-252 source ON Run 7724
Green is Cf-252 source OFF run 7726
HV_GEM= -2930 Volts HV_Cathode=-3400 Volts
Gas Flow rate = 0.1 ft^3/hr
- Goal
- Can the Cf-252 source ON signal be changed?
Change the Cathode voltage to try and turn off the signal when the source is on.
- Result
Yes, when the cathode voltage is decreased to -3200V, QDC histogram does not show any difference in the collected charge as the shutter is open with the source is on it, and when shutter is open without the source.
