环形加速器将射频加速单元替换为高重复频率连续运行的脉冲感应加速组元后,将具备新的性能特点和应用领域。日本高能加速器研究机构(KEK)在脉冲感应加速与环形加速器的结合方面开展了大量的研究和实验工作,通过对其相关研究的详细调研,结合在感应同步加速器实验研究中所遇到的具体问题,针对脉冲感应加速组元的固有特性对该类加速器的优势和局限进行了分析,对环形加速器中感应加速组元的发展方向提出了建议。

New acceleration characteristics of the circular accelerators employing pulse induction modules instead of radio frequency cavities are introduced. Combining the advantages of radio-frequency circular accelerator and linear induction accelerator, a new acceleration concept has been proposed by the Japan’s high energy accelerator research organization (KEK), and many researches and experiments have been carried out in recent years. This paper describes the details of such works, discusses the advantages and disadvantages of the pulse induction module when it is used in a circular accelerator, and advances some improvement proposals to the pulse induction modules, arming at solving the beam loss problems in the induction synchrotron experiments.
