WebThe operating principle of an ionization chamber is simple: ionizing radiation from the source (X- or gamma rays, electrons) creates an ionization of the gas atoms. A voltage is applied between the electrodes. … WebDETECTOR CHARACTERISTICS In normal use, the ceramic ion chamber is operated with the guard ring at ground potential and the shell electrode at -45 to -90 volts, depending on the gas filling. When it is necessary to suppress photoelectric emission from the walls completely, the shell electrode is operated at a positive poten- tial. In many applications, …
