Mercuric iodide (HgI2) solid state X-ray detectors have many unique advantages in their application to X-ray astronomy. HgI2 detectors operate at or near room temperature so that bulky and massive cryogenic coolers are not required. HgI2 detectors also combine a high quantum efficiency with good room temperature energy resolution. Because of the excellent quantum efficiency, background contributions that scale is the volume of the detector are lower than for other hard X-ray detectors with equivalent stopping power (e.g. germanium).
