Computer program TRACK_VISION for simulating optical appearance of etched tracks in CR-39 nuclear track detectors
A computer program called TRACK_VISION for determining the optical appearances of tracks in nuclear track materials resulted from lightion irradiation and subsequent chemical etching was described. A previously published software, TRACK_TEST, was the starting point for the present software TRACK_VISION, which contained TRACK_TEST as its subset. The programming steps were outlined. Descriptions ...
متن کاملOptical appearance of alpha particle tracks in CR-39 SSNTD
A ray tracing method based on geometrical optics was used to study the tracks from alpha particles with different energies and with an incident angle of 50 . The transmission operation mode of the microscope is simulated. Considering the distribution of light intensities from the tracks, the mean and the 80% percentile gray levels from real experiments are proposed as quantitative variables to ...
متن کاملOptical appearance of alpha-particle tracks in CR-39 SSNTDs
The optical appearance of etched alpha-particle tracks in CR-39 SSNTDs under the transmission mode of the optical microscope were studied. The mean grey levels revealed using a digital camera installed on the microscope, together with the major and minor axes were systematically determined for tracks from alpha particles with different incident energies and angles. The grey level properties for...
متن کاملA parameterization of nuclear track profiles in CR-39 detector
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 alpha particles. MATLAB based software is developed for this purpose. The software calculates and plots the depth, diameter, range, residual range, saturation time, and etch rate versus etching time. ...
متن کاملMeasurement of parameters of tracks in CR-39 detector from replicas.
In determining the etched track rate in solid-state nuclear track detectors, track lengths should be determined accurately. A method based on surface profilometry is proposed to determine the track lengths in CR-39 detectors through measurements of their replicas. Tracks from alpha particles with an incident energy of 4 MeV have been chosen to demonstrate the method. After irradiation and chemi...
