Profiles and parameters of tracks in the LR115 detector irradiated with alpha particles

The three-dimensional and analytical theory for track growth in solid state nuclear track detector is incorporated in a computer program for calculating track parameters and for plotting track-wall profiles and contours of the track opening in the LR115 detector irradiated by alpha particles. Some differences between the behavior of CR39 and LR115 detectors are discussed. Track parameters as well as the major and minor axes of the track openings have been calculated as a function of the energy and incident angle of the alpha particles. Vertical track profiles are given for incident angles between 20 and 90 and energies from 1 to 4 MeV, while the contours of track openings are given for incident angles from 10 to 90 and energies from 1 to 5 MeV. The track profiles and contours shown in the present study represent the tracks without any distortion. 2002 Published by Elsevier Science B.V.
