Abstract
The authors describe recent progress in the development of HgI2 energy dispersive X-ray detector arrays for synchrotron radiation research and their associated miniaturized processing electronics. A five-element HgI2 array detector was deployed under realistic operating conitions at Standford Synchrotron Radiation Laboratory, and an energy resolution of 252 eV FWHM (full width at half maximum) at 5.9 keV (Mn-Kα) was obtained. The authors also report energy resolution and throughput measurements versus input count rate. The results from the HgI2 system are compared to those obtained under identical conditions from a commercial 13-element Ge detector array
