A technique for correction of pulse heights from thick silicon particle detectors

Abstract When detecting protons with thick silicon detectors, it is sometimes desirable to use short pulse-shaping time constants in the associated amplifier. As the charge collection time varies for electrons and holes along the proton track, an energy dependent signal loss is observed when pulse shaping and charge collection times are comparable. A method for calculating the resulting nonlinearities in the proton energy scale is presented and corrections applied to the energy calibration are compared with experiment.
