TRIAC II. A MatLab code for track measurements from SSNT detectors

Abstract
A computer program named TRIAC II written in MATLAB and running with a friendly GUI has been developed for recognition and parameters measurements of particles' tracks from images of Solid State Nuclear Track Detectors. The program, using image analysis tools, counts the number of tracks and depending on the current working mode classifies them according to their radii (Mode I—circular tracks) or their axis (Mode II—elliptical tracks), their mean intensity value (brightness) and their orienta...

Title of program: TRIAC II

Nature of problem
Following the passage of a charged particle (protons and heavier) through a Solid State Nuclear Track Detector (SSNTD), a damage region is created, usually named latent track. After the chemical etching of the detectors in aqueous NaOH or KOH solutions, latent tracks can be sufficiently enlarged (with diameters of 1 Μm or more) to become visible under an optical microscope. Using the appropriate apparatus, one can record images of the SSNTD s surface. The shapes of the particle's tracks are stro ...

摘要
开发了一款基于MATLAB编写、搭载友好图形用户界面（Graphical User Interface, GUI）的计算机程序TRIAC II，用于从固体核径迹探测器（Solid State Nuclear Track Detector, SSNTD）的图像中识别粒子径迹并测定其参数。该程序借助图像分析工具统计径迹数量，并根据当前工作模式对径迹进行分类：模式I下依据径迹半径（圆形径迹）、模式II下依据径迹长轴（椭圆形径迹），同时结合其平均强度值（亮度）及取向进行分类。

程序名称：TRIAC II
目录编号：ADZC_v1_0

问题本质
当带电粒子（质子及重离子）穿过固体核径迹探测器（SSNTD）时，会在探测器内形成损伤区域，通常称为潜径迹。将探测器置于氢氧化钠（NaOH）或氢氧化钾（KOH）水溶液中进行化学蚀刻后，潜径迹可被充分放大（直径可达1微米及以上），从而在光学显微镜下可见。借助配套实验装置，可采集探测器表面的图像。粒子径迹的形态存在截断。
