Statistical Analysis of the Saturation of Charge Sensitive Pre-Amplifiers

The problem of the charge sensitive preamplifier (CSPA) saturation is considered. It is shown that statistical uncertainty of the CSPA saturation time intervals is small in real measurements and it is possible to apply a periodical programmable external reset of CSPA (as well as programmable protection of other electronic blocks in a spectrometer against distortions caused by the preamplifier reset pulse) without essential increase of the dead time
