摘　　要：相干太赫兹辐射已成为很多基础科学和应用科学研究的有力工具.给出了合肥光源改造工程电子储存环(HLS-Ⅱ)相干太赫兹运行模式的详细模拟过程.低动量紧缩因子模式和谐波腔模式是这里用于产生相干太赫兹的两种方法.还讨论了短束团运行模式中存在的问题,包括不稳定性引起的流强阈值、辐射功率以及纵向相空间的阻尼过程等.Coherent THz radiation has become an important research tool in many basic science studies and applied research. A detailed simulation process for coherent THz （terahertz） radiation at the HLS-Ⅱ （Hefei Light Source-Ⅱ） storage ring with 2 mm bunch lengths was presented. The low-alpha mode and harmonic cavity mode were two methods applied here for coherent THz radiation. The related issues of short bunch length, including beam instability threshold current, radiation power, and longitudinal phase-space damping progress, were also discussed.
