Abstract
PbO glass converters for the detection of gamma rays with MWPC have been investigated. The converters were made by fusing glass tubes stacked to form a close-packed array and were treated in a H2 reduction process to provide a suitable electric drift field. Electron conversion efficiency, drift velocity, and spatial resolution of these arrays were investigated. Using 511 keV gamma rays, an electron conversion efficiency of 8% was established for the converter of 80% PbO by weight (1.4 mm inner diameter, 0.1 mm wall thickness and 2 cm thick).
