ABSTRACT:
The invention relates to a spectroscopy method for analysing high count rate pulses in an electrical signal s(t) emitted by a radiation detector. The method comprises analogically sampling the signal s(t) and integrating the sampled signal over a duration equal to the sampling period (T); converting the sampled signal into digital samples; detecting pulses on the basis of the digital filtered samples, and determining the energy spectrum from the detected pulses.
The invention is applicable to detecting nuclear particles and radiation in well logging techniques.
