Determination of track etch rates from wall profiles of particle tracks etched in direct and reversed direction in PADC CR-39 SSNTDs

Computer program Neutron_CR-39 for simulation of neutrons from an Am–Be source and calculation of proton track profiles

“…Using these parameters the efficiency of CR-39 for the neutron detection was estimated. Our code takes into account the tracks etched in opposite as well as in the same direction and it is different in comparison to other group [15,[17][18][19]. Our results were not comparable with other authors.…”

“…For these tracks, the previously described mathematical model is not fully valid. The development of tracks etched reversely is described in [14] and experimentally was confirmed in [15]. This model is briefly described here.…”

“…If the particle is not stopped in the detector it is necessary to determine L start which is the lower integration limit in Eq. (15). L start represents the distance between the stopping point and the detector along the x-axis.…”

Investigations of protons passing through the CR-39/PM-355 type of solid state nuclear track detectors

“…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.…”

Digital holographic microscopy for recording and analysis of 3D images of etched tracks in LR-115 SSNTD

“…For the last case, track wall coordinates should be extracted from reproduced 3D track images by means of image analysis and computer calculations. The evaluation of track etch rates from track walls can be done by the secant [36] or the radius [37] method.…”
