METHODS FOR THE RAPID DECONVOLUTION OF THERMOLUMINESCENCE GLOW CURVES

Methods for the rapid deconvolution of thermoluminescence glow curves are described. By tailoring a least squares fitting routine specifically for glow curve deconvolution, we have achieved an order of magnitude reduction in unfolding time. For routine applications, where many similar glow curves are analysed, another order of magnitude reduction is achieved by fitting the glow curves to a previously determined set of glow peaks, rather than deconvoluting each glow curve into a unique set of glow peaks. For this case, a glow curve consisting of 200 data points can be deconvoluted into 12 glow peaks in less than 0.2 s.
