摘要
北京谱仪是北京正负电子对撞机上的一台大型通用性磁谱仪。它由多种探测器组成,用于测量正负电子湮没后的遍举末态反应,进行粲粒子物理和τ轻子物理研究。它有大的覆盖立体角;优良的荷电粒子分辨;动量分辨和好的低能光子探测效率。本文对谱仪的结构和性能作了详细的描述。
The Beijing Spectrometer (BES), as a general purpose magnetic spectrometer working at the Beijing Electron Positron Collider (BEPC), consists of several subdetectors. It is used for reconstruction of the exclusive final states from e^+e^- interaction and study of the charm physics and τ lepton physics. It has large solid angle coverage, excellent charged particle identification and momentum resolution, and high detection efficiency of low energy photons. The constitution and performances are given in detail.
