A personal-computer-based thermoluminescence data acquisition and analysis system for studies on low-temperature thermoluminescence glow peaks from photosynthetic material

Abstract

A personal-computer-based low-temperature thermoluminescence system has been developed for recording thermoluminescence from photosynthetic materials, in the temperature range from liquid nitrogen temperature (-196 degrees C) to +60 degrees C. Programmable and linear temperature-time profiles are provided by a dedicated microprocessor-based PID temperature controller. The PC/AT with an add-on card acquires the thermoluminescence data. This paper describes the thermoluminescence set-up, the interface to the personal computer and the software developed for acquisition, processing and analysis of the thermoluminescence data.
