Characteristics of a New Plastic Track Detector of the CZ Type

摘要

The registration parameters of a new plastic track detector (PTD) for nuclear particles have been experimentally investigated. The PTD is a modification of a CR-39 detector and is labeled CZ. As compared to the CR-39 detector with a similar chemical composition, the CZ PTD produced by the Semenov Institute of Chemical Physics from allyl diglycol carbonate (C_(12)H_(18)O_7) has a considerably higher sensitivity and better dynamical (the track etching rate and the rate of etch removal of a substance from the surface of a PTD plate) and geometrical (etchable track length and diameter) registration parameters. Based on results of the calibration experiments with a particles of different energies, fission fragments of ~(252)Cf, and accelerated ~(20)Ne ions, the theoretical estimate was obtained for the threshold value of the specific ionization losses, the sensitivity, and the detection efficiency for nuclear particles, beginning with protons.
