The detectors are cooled to liquid nitrogen temperatures (in order to achieve high resolution) and are surrounded by a thick anti-coincidence shield which allows the rejection of background events from true astrophysical events. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/GRIS_Ge_detectors/GRIS_Ge_detectors.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
