Abstract
The energy E of a signal pulse P inputted to an energy measurement apparatusfor measurement, and corresponding to the total integrated intensity, is calculated in an energy calculation unitfrom the integrated signal intensity Q acquired by a gate integrator, and from the pulse interval T measured by a pulse interval measurement unit. At this time, pileup correction is performed using at least one of the integrated signal intensity or the energy, and the pulse interval of the signal pulse inputted prior to the signal pulse for measurement. By this means, the correct energy E, with the effect of pileup eliminated, can be determined with good precision. Hence a method and apparatus for energy measurement are realized which enable correct and precise measurement of the energy of individual signal pulses, even when the pulse interval between signal pulses is short.
