Parallel plate ionization chamber
WebPlane Parallel Chambers. Plane parallel, sometimes called parallel plate, ionization chambers are commonly used in low energy (<6MeV) electron dosimetry as well as in … WebAn ionization chamber measures the charge from the number of ion pairs created within a gas caused by incident radiation. It consists of a gas-filled chamber with two electrodes; known as anode and cathode. The electrodes may be in the form of parallel plates (Parallel Plate Ionization Chambers: PPIC), or a cylinder arrangement with a coaxially ...
