Integral multi-sensor radiation detector

Claim 1

A multi-sensor radiation detector assembly, comprising, a closed end tubular first electrode forming an enclosure, an hermetically sealed interconnect member located in the enclosure end opposite to said closed end, a plurality of slightly spaced apart substantially identical tubular second electrodes positioned coaxially and concentrically in end to end relationship within the enclosure formed by said first electrode, electrical conductor means including a plurality of individual electrical conductors operatively connected to each of said tubular second electrodes and extending within said second electrodes through said interconnect member, and an electrical conductor operatively connected to said first electrode, means for providing an ionizAble environment between said first electrode and said second electrodes, each of said second electrodes forming a separate ionization chamber with said first electrode, and a voltage source generating a voltage of a predetermined magnitude, said voltage source being operatively associated with said electrical conductor means to apply substantially the same voltage potential difference across the electrodes of said respective ionization chambers.
