先进光子源 (APS) 是一种 7 GeV 存储环形光源，已经运行了十多年。为了对现有 APS 环的性能进行革命性改进，我们正在探索在 APS 复合体中添加 7-GeV 能量回收直线加速器 (ERL) [1]。在本文中，我们展示了此类系统的可能配置，同时考虑了 APS 站点的详细信息以及保留存储的波束能力的要求。我们展示了单通道 7-GeV 直线加速器的可能配置。我们讨论从 10 MeV 到 7 GeV 往返传输的光学解决方案，包括支持 48 条额外用户光束线的大型周转区。显示的跟踪结果包括不相干和相干同步加速器辐射，从而预测光束线性能。我们还证明了在高光束能量下运行的必要性。
The Advanced Photon Source (APS) is a 7-GeV storage ring light source that has been in operation for over a decade. In order to make revolutionary improvements in the performance of the existing APS ring, we are exploring the addition of a 7-GeV energy recovery linac (ERL) [1] to the APS complex. In this paper, we show the possible configuration of such a system, taking into account details of the APS site and the requirement that stored beam capability be preserved. We exhibit a possible configuration for the single-pass, 7-GeV linac. We discuss optical solutions for transport from 10 MeV to 7 GeV and back, including a large turn-around are that would support 48 additional user beamlines. Tracking results are shown that include incoherent and coherent synchrotron radiation, resulting in predictions of the beamline performance. We also demonstrate the desirability of operation at high beam energy.
