SEMICONDUCTOR DETECTOR SYSTEMS (dE/dx AND E) FOR THE DETECTION AND MASS IDENTIFICATION OF PROTONS, DEUTERONS, TRITONS, He$sup 3$ AND ALPHA PARTICLES IN THE 10- TO 30-MEV ENERGY REGION
The use of semiconductor detectors for investigation of particles in the region from 1O to 30 Mev is discussed. In this energy region, simple single- counter detecting systems cannot be employed except in special cases because of the many competing reactions which may obscure the reaction of interest. One method of separating the various particle groups so that they may be observed independently is through the use of a dE/dx detector in conjunction with a total energy or E detector. A system using a gas ion chamber dE/dx counter and a semiconductor E counter is described. A comparison of the C/sup 1//sup 1/ spectrum observed with a semiconductor system and a NaI system and the mass identification of a mixed beam of He/sup 3/ and He/sup 4/ particles are shown. A thin semiconductor dE/dx detector is described. The semiconductor dE/dx detector when used with a semiconductor E detector separated He/sup 3/ and He/sup 4/ particles in a manner similar to the gas ion chambersemiconductor dE/dx and E system. The mass separation was improved. Criteria for optimum energy resolution with dE/dx and E detector systems are presented. The use of coherent addition to improve the effective separation of a detector ts discussed. (M.C.G.)
