The high-density multiwire drift chamber

Abstract A multiwire proportional chamber, with a high-density drift space attached, has been developed as a position-sensitive detector for non-ionizing radiation. A chamber with a 5 g/cm 3 drift space, comprising a lead-bismuth matrix of 1 mm square holes on a 1.5 mm pitch has been investigated. For 0.66 MeV protons a detection efficiency of 5%, combined with a spatial resolution of 1.3 mm fwhm, is obtained. Much higher efficiencies are possible. A theoretical analysis of the detection efficiency as a function of photon energy is presented. It agrees well with experimental results. The chamber offers new possibilities for photon and neutron detection, and as a shower detector for high-energy particles.
