EXPERIMENTAL CALIBRATION OF SEMICONDUCTOR DETECTOR PULSE-HEIGHT RESPONSE TO PROTONS

摘要

Significant progress has been made toward accomplishing measurement of the energy 'absorbed from a proton as a function of the path length of the proton in the sensitive volume of a semiconductor detector. Surface barrier P-N and P-i-N detectors have been used in the study utilizing path lengths as short as 100 μand as long as. 10 cm. Protons of initial energy of 16, 40, and 187 Mev have been used. Other proton energies (8 to 166 Mev) were obtained by using absorbers in the proton bean. Energy calibrations were accomplished by total absorption of protons of known energy.
