目前锗半导体探测器的应用受到很大重视,用以解决一系列地质、物探问题,首先是用于分析岩石的元素组成。但直到目前为止,半导体探测器还很少用于测井,其原因是冷却系统的设计比较复杂。冷却系统应该使半导体探测器在液氮温度下(78°K)于封闭的探头体 At present, the application of germanium semiconductor detector has received great attention to solve a series of geophysical and geophysical problems. The first is to analyze the elemental composition of rock. Until now, however, semiconductor detectors have rarely been used for well logging because of the complexity of cooling system designs. The cooling system should allow the semiconductor detector to be immersed in a closed probe body at liquid nitrogen temperature (78 ° K)
