The level of development and application radiations technologies is largely determined by the state of nuclear instrumentation. The advent of modern semiconductor sensors for the first time connected nuclear instrumentation and electronics into a single complex - semiconductor detector. It combines a semiconductor primary converter of ionizing radiation (sensor), secondary converter of information from the sensor (electronics) and software for processing this information, interconnected in terms of problem being solved and parameters. The block diagram of the detector consists of two main parts: the primary converter of ionizing radiation (IR) energy into an electrical signal - sensor; secondary converter of this electrical signal. The characteristics of the detector are determined mainly by the physical properties of the semiconductor crystal as the sensitive element of the primary transducer, as well as by the features of process recording the electrical signal. The process of registering IR consists of con
