The efficiency of counter telescopes for detecting intermediate-energy protons
Abstract
The absolute efficiency of simple counter spectrometers for detecting protons with energies from 89 to 466 MeV has been measured experimentally. The inefficiencies due to nuclear interactions are in close agreement with calculations using available reaction cross-sections. In addition, an investigation was made of the dependence of the efficiency on the position of the proton incident on the counter. A simple mathematical model for the shape of the efficiency profiles is presented in order that the present results may be generalized to other detector geometries. The model is shown to fit the efficiency profiles for the present geometry very well.
