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 excellent tool for dynamic measurements. Daresbury Laboratory has developed 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 provide the highest quality system the performance of 3 different commercially available photodiode arrays has been evaluated. This paper presents the results of these evaluations and indicates the future direction of this project.
