Abstract:

The experimental characteristics of semiconductor particle detectors have been studied extensively to determine response, resolution, rise time, stability, and irradiation effects. Surface barrier detectors, diffused P-N junction detec tors, and ion-drifted P-i-N detectors have been exposed to many different energies of protons, electrons, photons, and neutrons. The character istics of the response of each type of detector to each type of ionizing radiation have been de termined as a function of geometry and operating conditions. This basic information concerning the detectors is being used to solve radiobio logic problems in the laboratory and in space. The applications include 1 particle identifica tion, 2 energy spectrum measurement, 3 energybed in the silicon from the ionizing parti cle, 4 translation of energy absorbed in sili con to energy absorbed in tissue, i.e., dose measurement, and 5 depth dose measurements by embedding detectors in animals.
