ABSTRACT:
Real-time correction of counting losses in the operation of a pulse-height analyzer, connected to the output of a radiation detector, is accomplished by establishing a gating interval at a time when the analyzer is available after processing the last detector pulse, this interval beginning at an instant delayed beyond the trailing edge of that last pulse by at least a predetermined rise time and ending with the leading edge of the next detector pulse. Test pulses generated during this gating interval are counted and their number is used to determine a probability ratio whose reciprocal constitutes a weighting factor; the digitized amplitude of each detector pulse addresses a corresponding memory cell whose contents are thereupon increased by the current weighting factor.
