北京谱仪Ⅱ的μ探测器的位置分辨和击中效率与带电粒子的动量和入射位置有关,利用选取的宇宙线样本和强子样本对μ探测器逐层进行了标度,并利用构造的效率比函数在物理分析中有效地识别μ和强子.
The momentum and polar angle depended position resolution and hit efficiency in each layer of BES( Ⅱ) muon detector are calibrated by using cosmic ray and hadron samples. Based on the calibration results, the efficiencies ratio function is constructed to separate Ⅱ effectively and applied in physics analysis.
