Abstract
A non-optical, pulsed reset technique for use in charge sensitive prea mplifiers with Si(Li) X-ray semiconductor detectors of conventional po larity is described. The phenomenon of impact ionization in the field effect transistor is used for charge restoration. The process is contr olled via the detector capacitance. The method needs no extra componen ts in the input circuitry. No significant resolution degradation can b e detected up to 600 kcps Mn K intensity if following the 5 mu s reset ting pulse the signal processor is inhibited for 50 mu s.
