A simplified numerical approach to non-radiation induced high-temperature signals in thermoluminescence. GlowVIEW - a useful tool for a multiple glow-curve analysis

A simplified numerical approach to the analysis of non-radiation induced high-temperature signals in thermoluminescence has been proposed. The approach is based on fitting a simple exponential function to arbitrarily chosen two data-points of the measured thermoluminescent glow-curve. The best matching function is then subtracted from the measured data. This method often gives better results as compared to the standard regression applied for a whole range of the measured thermal background. Results given by these two methods are also compared within this work. The proposed approach is the most effective in cases, when high-temperature thermoluminescent components are strongly covered by a thermal background. Such a data analysis is supported by a computer program GlowVIEW, developed at the Institute of Nuclear Physics in Krakow for a multiple glow-curve analysis. The program allows for a simultaneous processing of the unlimited number of the measured glow-curves. All the GlowVIEW's functionalities as well as their usefulness for a TL glow-curves analysis are also described in this work. The program undergoes a continuous upgrade process and most recent version can be freely downloaded from the web page:https://www.ifj.edu.pl/dept/no6/nz63/GlowVIEW.php.
