Mixed field dosimetry using focused and unfocused laser heating of thermoluminescent materials. Final report, Year 1, April 15, 1992--June 30, 1993

摘要

This work had as its original goals the theoretical evaluation of a unique method of performing mixed field dosimetry by using focused and unfocused laser heating to extract dose information from the superficial layers, followed by the deeper layers, of a single, thick thermoluminescent detector (TLD). This report will review the original stated goals for this award, then review the results obtained during the first year of the grant. Software tools required to accomplish these goals were completed during the first year of the grant, and preliminary simulated data were obtained. A modification to the approach, utilizing sequential laser heating with different pulse powers and durations and deconvolution of the resulting glow curves was devised as a method for obtaining more complete depth dose information. Optimization and error analysis of the method will be accomplished in detail during Year 2.
