Tu Jun Huang Xianguo Mu Long Su Rongbo Wu Zhongyi(China Acadeny of Engineering Physics,Mianyang,621900)
While Au-Si surface barrier semiconductor detector is used in hydrogen condition,alpha peak moves slowly toward the direction of low energy until it immersed electronics noise.The failure phenomenon of Au-Si surface barrier detector in hydrogen condition is introduced,and the rule of this phenomenon is summarized.On the basis of these,the reason of the hydrogen condition impact on Au-Si surface barrier detector is presented.
