本文将讨论利用新的高亮度BEPCII双环e（+）e（-）对撞机研究τ粲能区物理的BESIII的设计和建造。基于蒙特卡罗模拟和宇宙射线和束流测试结果，将给出预期的性能。在BESIII中，利用1 T超导螺线管中的圆柱形多层漂移室对带电粒子进行了跟踪和动量测量。带电粒子的识别与飞行时间系统的基础上结合dE/dx（每单位路径长度的能量损失）的漂移室中的测量塑料蒸发器。电磁簇射的能量由位于螺线管磁体内的Csl（Tl）晶体量热计测量。μ子是通过在一个钢磁轭中的电阻板室阵列来识别的。介绍了基于网络计算机的一级触发系统、数据采集系统和探测器控制系统。(C)2010爱思唯尔有限公司版权所有。
This paper will discuss the design and construction of BESIII, which is designed to study physics in the tau-charm energy region utilizing the new high luminosity BEPCII double ring e(+)e(-) collider. The expected performance will be given based on Monte Carlo simulations and results of cosmic ray and beam tests. In BESIII, tracking and momentum measurements for charged particles are made by a cylindrical multilayer drift chamber in a 1 T superconducting solenoid. Charged particles are identified with a time-of-flight system based on plastic scintillators in conjunction with dE/dx (energy loss per unit pathlength) measurements in the drift chamber. Energies of electromagnetic showers are measured by a Csl(Tl) crystal calorimeter located inside the solenoid magnet. Muons are identified by arrays of resistive plate chambers in a steel magnetic yoke for the flux return. The level 1 trigger system, data acquisition system and the detector control system based on networked computers will also be described. (C) 2010 Elsevier B.V. All rights reserved.
