COUNTING RATE MEASUREMENT BY INTERVAL SAMPLING
Mickey Crouch, George E. Haynam · Canadian Journal of Physics · 1953
Two methods are described for measuring high counting rates with a counting device having a long resolving time. Both methods are based on the deliberate introduction of a large but calculable counting loss to transform a high counting rate to a lower rate. Formulas giving the counting rate in terms of the reduced rate are presented, together with formulas for the standard deviation of the counting rate. The performance of circuits used to study one of the methods is described, and a comparison is made with conventional rate measurement methods. It is found that, while the relative simplicity of equipment is gained at the expense of speed of measurement, the latter sacrifice is not as severe as might be expected.
