闪烁计数器中闪烁体和光电倍增管之间常使用光导联接,普通光导较为简单,但当闪烁体为平板形,而光电倍增管为圆形时,为使光电倍增管不受辐照或磁场的影响,就需要特殊形状的光导。 为了有较好的收光效率,要求光导材料透明度好,几何形状有利于光的传输。D·luckey等首先提出制成扭曲条状光导,以后不断得到改善,在核物理和高能物理实
The scintillation counter and the photomultiplier tube are often used between the scintillation counter and the photoconductors. The common light guide is relatively simple. However, when the scintillator is a flat plate and the photomultiplier tube is circular, in order to make the photomultiplier tube free of irradiation or magnetic field Influence, you need a special shape of light guide. In order to have better light-harvesting efficiency, it is required that the light-guiding material has good transparency and the geometric shape facilitates the light transmission. D · luckey first proposed made of twisted strip light guide, after continuous improvement, nuclear physics and high energy physics
