Optical 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 کاملComputer 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 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 کاملUse of chemical etching of CR-39 foils at elevated temperature for fast neutron personnel monitoring in India
CR-39 Solid State Nuclear Track Detecting foils (SSNTD), along with 1 mm thick polyethylene radiator, sealed in triple laminated pouches, are used for country wide Fast Neutron Personnel Monitoring in India. With the present system of processing by elevated temperature electrochemical etching (ETECE) and evaluation using automatic image analysis, only 16 foils are processed at a time and it is ...
