Methods of the processing of signal from detectors of ionizating radiation, spectroscopical systems, data processing and overview of the related electronics.


Knowledge of the detectors of ionizing radiation and overview of electronics.

Syllabus of lectures:

1. Basic systems for ionizating radiation measurement.Keystones of pulse electronics, signal, impedance, C-R and RC circuits, pulse transformator.
