Abstract

A method is described for measuring signals generated by a detector of ionizing particles and/or radiations, said signals being made available as electric charges at the outputs of the detector, the method being adapted for use within a multichannel environment with VLSI or higher technology and comprising the steps of: removing all said electric charges at a constant rate from said outputs of the detector, by using a type of preamplification in linear or saturation conditions; measuring the time necessary for removing all said electric charges; converting said time into a measurement of the quantity of said electric charges; defining an event of a succession of events as characterized by all said electric charges, said measurement being referred to said event; eliminating from said measurement a contribution relating to electric charges of all previous events.
