“…5,6 The problem of the development and simulation of etched track profiles in CR-39 material and comparison with experimental results for light ions of different kinds and energies has been the subject of many studies in recent years. [7][8][9][10][11][12][13] The currently existing computer programs calculate the depth, diameter, range, saturation time, and etch rates versus etching time. The simulation programs reasonably approximate the experimental three dimensional track images for protons, α particles, and Li ions.…”

Solid State Nuclear Track Detectors of the CR-39/PM-355 type were irradiated with protons with energies in the range from 0.2 to 8.5 MeV. Their intensities and energies were controlled by a Si surface barrier detector located in an accelerator scattering chamber. The ranges of protons with energies of 6-7 MeV were comparable to the thickness of the PM-355 track detectors. Latent tracks in the polymeric detectors were chemically etched under standard conditions to develop the tracks. Standard optical microscope and scanning electron microscopy techniques were used for surface morphology characterization.

Computer software for calculation of the sensitivity of a CR-39 detector closed in a diffusion chamber to radon is described in this work. The software consists of two programs, both written in the standard Fortran 90 programming language. The physical background and a numerical example are given. Presented software is intended for numerous researches in radon measurement community. Previously published computer programs TRACK_TEST.F90 and TRACK_VISION.F90 [D. Nikezic and K. N. Yu, Comput. Phys. Commun. 174, 160 (2006); D. Nikezic and K. N. Yu, Comput. Phys. Commun. 178, 591 (2008)] are used here as subroutines to calculate the track parameters and to determine whether the track is visible or not, based on the incident angle, impact energy, etching conditions, gray level, and visibility criterion. The results obtained by the software, using five different V functions, were compared with the experimental data found in the literature. Application of two functions in this software reproduced experimental data very well, while other three gave lower sensitivity than experiment.

“…While the measurements of track-opening diameters are relatively straightforward, direct measurements of track lengths are relatively difficult (Hermsdorf, 2009). However, track etch rate, V T and sensitivity function V, are usually determined through measurements of track-opening diameters (Hermsdorf and Reichelt, 2010). Analysis of tracks produced by protons, alpha particles or nuclear fission fragments in SSNTDs constitutes a very important tool in various areas (Ilic et al, 2003).…”

In this paper, the bulk etch rate, V B of the CR-39 detector employed, was found experimentally to be equal to 1.49µmh-1. Detector samples were irradiated with alpha particles energies from 1 to 5MeV and incident angles from 20 • to 90 •. After etching in a 6.25N NaOH solution kept at (70±1) ˚C , the lengths of major and minor axes of the alpha track openings were measured, and the track etch rate, V T for normal and oblique incidence was calculated. The relationship between V T and the track depth, x of the alpha particle in the detector for normal incidence was studied. Track length, L and track length growth rate, dL/dt were also calculated. These data were used altogether to derive a V function, which took the functional form of the Brun's function with new constants (a 1 =0.091, a 2 =1.2, a 3 =1.6, a 4 =1.61, a 5 =1.425). Experimental V function was compared with those computed by TRACK-VISION program, and a good agreement with three of them was found.
