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.
Claims8
A spectroscopy method for analyzing high count rate pulses in an electrical signal emitted by a radiation detector, said pulses representing nuclear radiation, the amplitude of said pulses being a representation of the energy of particles in the radiation, the method comprising the steps of:
- analogically sampling said electrical signal with a sampling period and integrating the sampled signal over a duration equal to said sampling period;
- converting the integrated sampled signal to digital samples;
- detecting pulses from said digital samples;
- and
- determining an energy spectrum from said pulses.
