Three-dimensional track imaging during etching and sequential reconstruction of track structures

Abstract

Three-dimensional (3D) image processing for analysis of track etching in a Solid State Nuclear Track Detector (SSNTD) was performed. A SSNTD in contact with boron nitride films was exposed to epithermal and thermal neutrons. In chemical etching process, sequential images of etch-pits on the surface of the SSNTD were obtained with a developed observation system. By use of a digital-image-processing technique, 3D images were reconstructed from data on sequential surface images of the track detector for particles released due to 10 B ( n , α ) 7 Li reactions.
