摘要

The detection efficiencies of a position sensitive parallel plate avalanche counter, measured with 40MeV/u ¹⁷N beam bombarding on a 621mg/cm^{2 197}Au target, were observed to be significantly different for different ions from helium to oxygen. Furthermore, for a given type of ion, the efficiency decreases with the increase of the incident energy.
