The thermoluminescence (TL) apparatus used for the MMA-BNL dating project has been especially designed to improve upon light collection and transmission properties, when compared to most currently used dating systems. Two methods of light collection have been developed: one employing aspheric reflectors and the other using a reflector and lens system. In order to compare the relative effectiveness of these two systems, and to compare their performance against theoretical predictions or future improvements, a standard lamp and housing has been developed and calibrated. Two types of miniature lamps were evaluated for this purpose and their characteristics are shown in tables. (ERA citation 04:014475)
