BKG effect with the paddle detector:
, , ,
Upstream collimator diamater = 0.25"
Downstream collimator diamater = 2.0"
2 Al sheets as bremsstrahlung radiator;
Detector G: HV(G1) = -1700 V, HV(G2) = -1650 V.
There was 2" of lead in front of the Det G. Det G was placed on the floor.
Case A: Target out, radiator in - Counting rate (G1) = 1/168 (gammas/pulse)
Case B: Target out, radiator in, downstream collimator blocked - Counting rate (G1) = 1/485 (gammas/pulse)
