A STUDY OF GERMANIUM SURFACE BARRIER COUNTERS
The properties of Ge surface barrier counters at low temperatures were inveatigated. Development work on a compact radiation detector suitable for counting alpha particles and fission fragments from nuclei oriented at low temperatures is reported. It was found that, under proper operating conditions, Ge surface barrier counters make excelleat detectors for short-rsnnge charged particles. Apparent freedom from direct recombination makes them useful for pulse resolution in the case of panticles which create different specific ionization densities. Their very fast rise time makes them useful in fast coincidence couating. Compact couaters with sensitive areas ranging in size and shape from 3 mm square to 1 inch in diameter are described.
