WebNeutrons can be detected using helium-3-filled gas proportional counters (Fig. 1). A typical counter consists of a gas-filled tube with a high voltage applied across the anode and cathode. A neutron passing through the tube will interact with a helium-3 atom to produce tritium (hydrogen-3) and a proton. [5] The proton ionizes the surrounding ... WebAs a result, there are three basic types of gaseous ionization detectors, which are categorized according to the voltage applied to the detector: ionization chambers, proportional counters, Geiger-Müller tubes. As with other detectors, ionization chambers can be operated in current or pulse mode.
