摘要
简要描述了北京谱仪(BES)主漂移室的结构和宇宙线实验安排,给出利用宇宙线测试主漂移室性能的主要结果.单元内具有线性的漂移距离S-漂移时间T关系.室的单丝空间分辨率σ_x-210～240μm.相当室内40次dE/dx取样的能量分辨率为8.77％.主漂移室运行稳定.
The structure of the BES main drift chamber and arrangement of cosmic ray tests have been described briefly. The main test results of the chamber performance have been given. There are S-T relations with good linearrty in the cells. The spatial resolution of 210-240μm has been obtained for single wire. The energy resolution corresponding to 40 samples in the chamber is 8.7%.
