Chamberlain, J E

An ionization chamber for measuring the profile of a radiation field is provided which comprises a first electrode and a second electrode arranged parallel to said first electrode, both electrodes forming a gap therebetween. A shield made of a material opaque to ions produced by the radiation field is movably arranged in said gap between said electrodes and has an aperture, which between said electrodes forms a measuring volume. The ionization chamber further comprises means for moving said shield together with said aperture along said gap between said electrodes.
