摘要: We present detailed studies of the physical mechanisms underlying collection charge carriers and thermal energy in a heat/ionization germanium particle detector operated at 20–28 mK, together with presentation its main performances. This is devoted to search dark matter particles, taking advantage double signal reject background induced events. In what concerns ionization channel, current–voltage characteristics, resolution, time stability, pulse height bias dependence are presented. A mechanism proposed explain fact that p-i-n diode maintains some rectifying properties spite very low temperature. The resolution 1 keV full width half maximum (FWHM) 86.5 keV, stability several days. calculation carrier trapping contribution performed results compared data. interpreted within “hot” ...
