Abstract:
A position sensitive multiwire proportional counter with integral delay line including a support carrying a plurality of anode wires and at least one cathode wire spaced in a predetermined relationship from the anode wires within the active volume of the counter to form an integral delay line. The counter is filled with a gas which ionizes upon interaction with ionizing radiation, the ionization of the gas being enhanced by the positive anode, such that an electrical charge is thereby induced in the cathode wire. Sensing of elapsed time between receipt of the induced charge at opposing ends of the cathode wire is utilized to determine the desired radiation positional data.
