Abstract：
In this paper, the recording energy range and efficiency of cellulose acetate trackdetector (made by Shanghai Film Works) to proton and deuteron registration were de-termined, and the upper limit of recording energy to α-particle registration was dete-rmined too The highest energies of α-particle, proton and deuteron registrated are11.7, 0.8 and 1.35 MeV respectively. At a certain removed layer thickness range, theefficiencies of vertical incident protons with energy 400--900 keV and deuterons withenergy 450--1350 keV registrated are all 100%. The model of restricted energy lossproposed by Benton was tested for the sensitive cellulose acetate track detector usingprotons, deuterons and alpha particles. It is shown that. the model may be applied tolight particle registrations. For these light particle registrations by the detector, thereis a functional relation between the etching rate ratios and ranges, thetefore, it maybe used to identify light particles.
