METHOD FOR MEASURING THE PULSE-COUNTING RATE, USING AN EXTENDIBLE DEAD-TIME METHOD WITH LIVE-TIME MEASUREMENT

摘要

The invention relates to a method for measuring the pulse-counting rate, using an extendible dead-time method with live-time measurement. According to the invention, N consecutive pulses Ii are acquired, in which 1 ≤ i ≤ N; the duration Di of each pulse Ii and the duration Ti of the interval between one pulse and the preceding pulse Ii-1 are determined, where Ti is the interval between the start of acquisition and the start of the first pulse; for every index i, the total acquisition time Ttot is updated, adding TiDi, where Ttot = 0 initially, and if Ti ≤ Tm (Tm being the imposed extendible dead time), the index is changed to i+1, or if Ti Tm, the live-time duration Ta-tot is updated by adding Ti-Tm, where Ta-tot = 0 initially, a variable C equal to the number of pulses detected outside of dead time is updated by adding 1, where C = O initially, and the index is changed to i+1. The counting rate is equal to the final value of C divided by the final value of Ta-tot.
