ABSTRACT:
A detector for ionizing radiation comprising a generally cylindrical enclosure which contains an ionizable gas, a central wire which with a peripheral wall constitute the electrodes of the device, and a window to permit entry of ionizing radiation. With appropriate potentials applied to the central wire and peripheral wall, ionizing radiation produces electrons which are attracted to the central wire and positive ions which are attracted to the peripheral wall in proportion to the intensity of the radiation. One or more auxiliary electrodes are provided which extend parallel to and between the central electrode and the peripheral wall. An appropriate potential is applied to this auxiliary electrode to neutralize the positive ions.
