高纯锗探测器具有极高的能量分辨率,高探测效率等优点,在核电、环境监测、生物医学、核物理与航空航天、地质、法学、考古学、冶金和材料科学等许多科学领域得到了越来越广泛的应用。2013年我们对高纯锗探测器进行了研究,设计并制备了P型同轴高纯锗探测器,具体制备过程如下:1)探头成形,购买的高纯锗晶体是圆柱形,首先在晶体表面加工一孔,构成单开端同轴结构,然后对孔内和样品表面进行研磨,保证孔内及表面不得有划道;2)N+层制备,在真空中把 High-purity germanium detector with high energy resolution, high detection efficiency, etc., in nuclear power, environmental monitoring, biomedical, nuclear physics and aerospace, geology, law, archeology, metallurgy and materials science and many other scientific fields More and more widely used. In 2013, we studied the high-purity germanium detector, and designed and prepared a P-type high purity germanium detector. The specific preparation process is as follows: 1) The probe is shaped and the purchased high purity germanium crystal is cylindrical. First, Surface processing of a hole to form a single open coaxial structure, and then the hole and the sample surface grinding, to ensure that the hole and the surface without scribing; 2) N + layer preparation, in a vacuum
