2-PARAMETRIC METHOD FOR SILICON DETECTOR CALIBRATION IN HEAVY-ION ANDFISSION FRAGMENT SPECTROMETRY

A new procedure has been proposed for the calibration of silicon semic onductor detectors in heavy ion spectrometry. This method exploits a t wo-parametric empirical equation for the value of pulse-height defect (PHD) in detectors versus masses and energies of recorded ions. A conv enient practical guide using the mean channel values of light- and hea vy-fragment groups in spontaneous fission of Cf-252 has been developed for determining the parameters of the PHD description for a given det ector. The method being applied to heavy ion spectrometry with Si-surf ace-barrier detectors and p-i-n diodes has demonstrated good results i n a large range of masses and energies.
