Detection Efficiency for alpha Particles (1.25 MeV < E < 3.3 MeV) in a LR 115 Spark Counter

摘要

In order to detect neutrons at an energy below 1.5 MeV, a track detector dosimeter has been investigated using a (n, alpha ) converter. The counting is made by an improved spark counter. The detection efficiency for alpha particles with different energies is carefully examined for different thicknesses of the detector to determine the best conditions of utilization.
