  2. BESIII探测器 BESIII由主漂移室(MDC),飞行时间计数器(TOF),电磁量能器(EMC),μ子计数器以及超导磁铁等系统组成。各子探测器的主要设计指标为:MDC:小单元结构和He基气体, 空间分辨xy=130m, 动量分辨 p/p = 0.5%@1GeV,和dE/dx=6%。EMC:采用CsI晶体,能量分辨 E/E = 2.5%@1GeV,位置分辨z = 0.6 cm@1GeV 。TOF:时间分辨:T = 100 ps(筒部), T = 110 ps (Endcap)。μ子计数器:9 layers RPC。超导磁铁:场强为1.0 Tesla的超导螺线管磁铁。

  3. BESIII探测器总体设计 北京谱仪(BESIII)的主体机械结构高9米、长11米、宽6米,总重650吨,是各子探测器的结构基础,同时是10000高斯超导磁铁的桶部轭铁、端部轭铁、极头,和谬子探测器的多层吸收体。
