EXPERIENCE OF 3 TYPES OF COMMERCIALLY AVAILABLE PHOTODIODE-ARRAY IN THE DARESBURY LABORATORY ENERGY-DISPERSIVE EXAFS DETECTOR SYSTEM

The technique of Energy Dispersive EXAFS is well established as an exc ellent tool for dynamic measurements. Daresbury Laboratory has develop ed a photodiode array based detector system for synchrotron radiation Energy Dispersive EXAFS experiments which allows high quality data to be collected in time scales of less than a second [1]. In order to pro vide the highest quality system the performance of 3 different commerc ially available photodiode arrays has been evaluated. This paper prese nts the results of these evaluations and indicates the future directio n of this project.
