摘要
基于τ 粲能区的物理目标和各物理过程的截面 ,估计了该能区新一代加速器典型亮度下的事例率和每年运行取得的事例数 .指出加速器亮度应优化在ψ″和ψ( 4 1 60 )之间 ,峰值亮度决定于探测器触发判选系统、电子学系统及数据获取系统等能处理的最高事例率 .
It is of great interest to build a high luminosity accelerator in τ-charm energy region. The physics interest in this energy region is briefly reviewed. Events rate and events number at different energy in one year's data taking are estimated under typical luminosity of 10 33cm -2s -1. It is pointed out that the luminosity of a newly designed accelerator should be optimized between ψ″ and ψ(4160), the peak luminosity should be determined by the events rate which the trigger system, detector electronics and data acquisition system could handle. =
