Energy loss in polycarbonate and polyethylene terephthalate by 2.0–6.5 MeV 14N, 31P and 75As ions

Abstract

Energy loss for 2.0–6.0MeV 14N ions, 3.0–6.5MeV 31P ions and 3.0–6.5MeV 75As ions in thin foils of polycarbonate and polyethylene terephthalate were measured by means of a transmission technique using a half-covered silicon surface barrier detector. During the measurement, the charged particle count rates were kept below 100cps in order to minimize dead time and radiation damage in the system. The obtained data are compared with the SRIM 2003 calculation and the ICRU Report 73. Most of the measurement results compare quite favorably with the ICRU Report 73.
