摘要
In this work, the empirical parameterization describing the alpha particles' track depth in CR-39 detectors is extended to describe longitudinal track profiles against etching time for protons and particles. MATLAB based software is developed for this purpose. The software calculates and plots depth, diameter, range, residual range, saturation time, and etch rate versus etching time. The predictions are compared with other experimental data and with results of calculations using the software, TRACK_TEST, developed for alpha track calculations. The software related to this work is downloadable and performs calculations for protons in addition to alpha particles.

Nature of problem:
A new semispherical parameterization of charged particle tracks in CR-39 SSNTD is carried out in a previous paper. This parameterization is developed here into a MATLAB based software to calculate the track length and track profile for any proton or alpha particle energy or etching time. This software is intended to compete with the TRACK_TEST [1] and TRACK_VISION [2] software currently in use by all people working in the field of SSNTD.
Solution method:
Based on fitting of experimental results of protons and alpha particles track lengths for various energies and etching times to a new semispherical formula with four free fitting parameters, the best set of energy independent parameters were found. These parameters are introduced into the software and the software is programmed to solve the set of eqbations to calculate the track depth, track etching rate as a function of both time and residual range for particles of normal and oblique incidence, the track longitudinal profile at both normal and oblique incidence, and the three dimensional track profile at normal incidence.
Running time:
1-8 s on Pentium (4) 2 GHz CPU, 3 GB of RAM depending on the etching time value
