本实验室自行研制了一套低本底反康普顿 g 谱仪。谱仪主探测器为美国ORTEC公司生产的GEM-100210 (P型) 非Pop Top 型同轴HPGe探测器,对60Co的1 332.5 keV 闵湎叩哪芰糠直媛?FWHM)为1.88 keV,相对效率为115.7%。该谱仪以环形和柱形NaI(Tl)组成井形反符合屏蔽探测器,以钢、铅及
The laboratory developed a set of low background anti-Compton g spectrometer. The main detector of the spectrometer is GEM-100210 (P type) non-Pop Top coaxial HPGe detector manufactured by ORTEC Corporation of the United States of America, which is 1.88 keV with respect to the 60Co at 1 332.5 keV (FWHM) Efficiency is 115.7%. The spectrometer to ring and column NaI (Tl) composed of well-shaped anti-compliance shielding detector, steel, lead and
