一、引言金-硅面垒型探测器是目前最为成熟、运用最为广泛的一类半导体射线探测元件。在低能核物理领域中,它所具有的极高的能量分辨率、极短的脉冲上升时间等优点,已经用于α粒子、β粒子、质子及其它各种重带电粒子的探测,dE/dX,E的测量,以及各种谱仪。利用中子与某些物质的作用可以测量中子,尤其是由于它的体积小,可以精确地测出中子通量的空间分布。这是以往大型中子探测器所办不到的。在保健物理及其它同位素应用中,配合晶体管线路可 I. INTRODUCTION The gold-silicon surface barrier detector is the most mature and most widely used type of semiconductor radiation detector. In the field of low energy nuclear physics, it has the advantages of high energy resolution, very short pulse rise time, etc. It has been used for the detection of α particles, β particles, protons and other heavy charged particles, dE / dX , E measurements, and various spectrometers. The neutron can be measured by the action of neutron and some substances. Especially because of its small size, the spatial distribution of neutron flux can be precisely measured. This is what previous large neutron detectors could not do. In health physics and other isotope applications, with the transistor circuit can be
