Abstract

PALACIOS, D. et al. Analysis and correction of track overlapping on nuclear track detectors (SSNTD). Rev. mex. fis. [online]. 2011, vol.57, suppl.1, pp. 34-39. ISSN 0035-001X.

The problem of nuclear track overlapping is addressed assuming the stochastic character of charged particle registry and the fact that even monoenergetic beam perpendicularly impacting on detector surface will show a distribution for track radius values. Asymmetric distributions of overlapping tracks were obtained for very low or very high simulated track quantities, while for intermediate values the distributions were well described by Gaussians. A model for the track overlapping process was developed, considering the dependence of the quantity of non overlapping tracks on the number of simulated tracks by a second order homogeneous differential lineal equation. Its solution contains only one free parameter that is related to track geometry and field view área. By successive approximations, the number of total induced tracks (which is proportional to particle fluence) is determined from the knowledge of the amount of non overlapping tracks, dimensions of the field view and average track radius.
