Testing of the counters by the detection of alpha particles and by other means is reported and a description of their application to the detection of 900 kev. He 3 particles from the D(d,n)He3 reaction and the special precautions which must be taken to prevent damage from scattered deuterons is given. The nature of this damage is discussed. A brief description is given of some further applications of the detectors.pdfen-NZNuclear countersSemiconductor nuclear countersSilicon diodesText
