Place of HgI2 energy-dispersive X-ray detectors
Abstract
After a review of solid-state conduction counters, in general, and of the history of mercuric iodide, in particular, the theory of operation of solid-state energy-dispersive HgI2 detectors is discussed. The main factors which limit energy resolution in solid state compound detectors are considered, including statistical fluctuations in charge generation, the window effect, trapping, inhomogeneities in the detector material, and electronic noise. Potential applications of room-temperature HgI2 X-ray fluorescence analysis with HgI2. Directions of current investigations are given.
