MODEL OF PHYSICAL PROCESSES IN PRIMARY AND SECONDARY CONVERTERS OF THE DETECTOR

The level of development and application radiation technologies is largely determined by the state nuclear instrumentation. advent modern semiconductor sensors for first time linked instrumentation electronics into a single complex - detector. It combines primary converter ionizing (sensor), secondary information from sensor (electronics) software processing this information, interconnected in terms problem being solved parameters. structural diagram detector consists two main parts: (IR) energy an electrical signal sensor; signal. characteristics are mainly physical properties crystal as sensitive element converter, well features process recording registering IR converting non-electrical quantity characterizing it In other words, converts one type another, more convenient accumulating information. A current or voltage pulse arises directly result ionization its active medium semiconductor; carries extensive First all, correlated with moment process. addition, marks fact that emitted within solid angle at which visible source. Pulse amplitude often measure loss sensor. shape different types radiation, areas angles hitting work, model gamma has been created system converters. contains analysis analytical presentation processes occurring CdZnTe-sensor electronic preamplifier. shown charge collection differs time, leads to spread pulses duration amplitude. regard, shows need use charge-sensitive advantage solution optimizing signal-to-noise ratio
