WebProportional counter. The proportional counter is a type of gaseous ionization detector device used to measure particles of ionizing radiation. The key feature is its ability to measure the energy of incident radiation, by producing a detector output pulse that is proportional to the radiation energy absorbed by the detector due to an ionizing ... Web2 jan. 2024 · Practical ionization chambers such as the Farmer chamber [10] have a wall thickness of about 1 mm. This is sufficient to produce electronic equilibrium for photons generated at kV energies, but is insufficient for megavoltage energies when an additional tight-fitting build-up cap is needed to increase the effective wall thickness.
