IMPROVED TECHNIQUE FOR MEASURING FLUORESCENCE DECAY TIMES IN THE NANOSECOND AND SUB-NANOSECOND RANGE

A new method for accurately recording scintillation pulse contours and for determining their decay times is reported. The novelty of this technique centers around the averaging, storing, and analyzing capabilities that are provided by an on-line, 8K mini-computer. Decay time measurements can be made by employing either pulsed UV, or ionizing radiation such as α or β particles, as excitation sources. Programs have been developed to convolute time resolved spectra with a single decay time. © 1979.
