【摘要】 制造了两块尺寸皆为50cm×50cm(厚5mm)的闪烁描迹仪(闪烁体为ST401型),利用安装在四角的四个光电倍增管的输出脉冲幅度的分析来达到定位的目的。研究了两种不同形状的光导对位置分辨的影响。其中较好的一种对单个带电粒子的位置分辨率为±2cm—±4cm。更多还原

【Abstract】 Two scintillation hodoscopes with the same dimension (50×50×0.5 cm~3) but dif-ferent shape of light guide have been built with the scintillator type ST 401. Analysing the amplitudes of outputs from four photomultlpliers, the position ofincident particles is definite. The effect of the two shapes of light guide on the posi-tion resolution has been studied. The position resolution of the better one is ±2 cmto ±4cm.更多还原
