Abstract

A dual-energy electron storage ring is a novel concept initially proposed to cool hadron beams at high energies. The design consists of two closed rings operating at significantly different energies: the low-energy ring and the high-energy ring. These two rings are connected by an energy recovery linac (ERL) that provides the necessary energy difference. The ERL features superconducting radio-frequency (SRF) cavities that first accelerate the beam from the low energy

E_{L}

to the high energy

E_{H}

and then decelerate the beam from

E_{H}

E_{L}

in the next pass. The different SRF cavities in the ERL section can be adjusted based on the applications. In this paper, we present a possible layout of a dual-energy electron storage ring. The preliminary optics of the ring is designed to optimize chromaticity correction, dynamic aperture, momentum aperture, beam lifetime, radiation damping, and intrabeam scattering effects. The primary focus of this paper is on the stability conditions and beam dynamics studies associated with this storage ring.

双能量电子储存环

双能电子储存环是一个新颖的概念，最初是为了冷却高能量的强子束而提出的。该设计由两个在明显不同能量下运行的封闭环组成：低能量环和高能量环。这两个环由一个能量回收直列加速器（ERL）连接，ERL 提供必要的能量差。ERL具有超导射频（SRF）腔，首先将光束从低能EL加速到高能EH，然后在下一个通道中将光束从EH减速到EL。ERL 部分的不同 SRF 腔可根据应用进行调整。本文介绍了双能量电子存储环的可能布局。环的初步光学设计旨在优化色度校正、动态孔径、动量孔径、光束寿命、辐射阻尼和束内散射效应。本文的主要重点是与该存储环相关的稳定性条件和光束动力学研究。
