Position-sensitive detector with microstrip anode for electron multiplication with gases

Abstract

A position-sensitive detector of a new type has been developed. A microstrip anode replaces the wires generally used for electron multiplication with gases. The microstrips which are fixed on a glass substrate are produced by means of photolithography. The applied electric potential alternates between each strip. With a position-sensitive neutron detector equipped with this new type of anode a counting rate of 2.3 MHz/cm2 has been measured. The microstrip anode combines the improved qualities of a proportional counter with certain properties of a photomultiplier tube. © 1988.
