Description of current pulses induced by heavy ions in silicon detectors (II)

Abstract : Current pulses induced in a silicon detector by 10 different heavy ion species at known energies around 10 AMeV have been sampled in time at high frequency. Their individual average shapes are quite well reproduced by a fit procedure based on our recent charge carrier collection treatment which considers the progressive extraction of the electrons and holes from the high carrier density zone along the ionizing particle track. This region is assumed to present a supplementary dielectric polarization and consequently a disturbe delectric field.The influence of the nature of the heavy ion on the values of the three fit parameters is analyzed.
