Development of Au-Si surface barrier 8~ Be detector 金硅面垒~8Be探测器的研制
Under reverse bias if frequency of small AC signal exceeds some value, the junction capacitance of Au-Si surface barrier detector will decrease. 在反向偏压下,测试时所用的高频小信号频率超过一定值后,GM型探测器结电容测试值将下降。本文讨论了频率对CV特性影响的实验结果,并分析了其原因。
Recovery of performance of Au-Si surface barrier detector contaminated 被污染Au-Si表面势垒探测器性能的恢复方法
A semiconductor fast neutron spectrometer consisting of a Au-Si surface barrier detector and a conical polyethylene foil radiator is described. 本文描述了一个由金硅面垒型探测器和锥形面聚乙烯薄膜辐射体所组成的快中子谱议。
The methods of performance recovery by cleaning and disposal for Au-Si surface barrier detector that performance deteriorated and can't be used normally owing to be contaminated by radioactivity materiel, powder and oil, have been recommended. 介绍了金硅面垒探测器因放射性的污染或粉尘、油渍等污物的沾附,致使其性能变坏而无法正常使用时,通过清洗和一定的处置使其性能恢复的方法。
