Zusammenfassung:Recent progress in the development of HgI/sub 2/ energy dispersive X-ray detector arrays and associated miniaturized processing electronics for synchrotron radiation research applications is described. The experimental results with a 20-element array detector were obtained under realistic synchrotron beam conditions at SSRL. An energy resolution of 250 eV at 5.9 keV was achieved. Energy resolution and throughput measurements versus input count rate and energy of the incoming radiation have been measured. Extended X-ray absorption fine structure spectra were taken from diluted samples simulating proteins with nickel.< >
