基于能量回收直线加速器（ERL）和储存环组合的光源是下一代光源的可行方案。我们提出了一个系统，其中一束的ERL循环通过两个或四个匝的存储环。该系统由多个偏转腔和静态偏转磁体组成。采用这种系统，环的平均电流可以比ERL的平均电流高出两到四倍，从而减轻了ERL的负担。低的聚束电流可以产生高质量的ERL束，低的ERL平均电流可以产生多程方案。
A light source based on the combination of an energy-recovery linac (ERL) and a storage ring is a feasible scheme for next generation light sources. We propose a system with which a beam of an ERL circulates through two or four turns in a storage ring. The system consists of several deflecting cavities and static deflecting magnets. With this system, the average current of the ring can be two or four times higher than that of the ERL, thus easing the burden on the ERL. Resultant low bunch current can lead to a high quality ERL beam and low average current of the ERL can lead to a multipass scheme.
