为了使光源紧凑和节能，可以使用能量回收超导RF LINAC。我们建议一个双轴，非对称腔，而不是传统的单轴，对称腔配置产生平均电子束电流超过1 A，同时仍然避免发展的束分裂不稳定性（BBU）。非对称腔的使用允许增加参与BBU不稳定性发展的HOM的启动电流，以及打破正反馈，导致高平均电流电子束被驱动而没有损失通过系统的能力。在这项工作中，一个非对称腔的实验研究的结果，并与理论预测进行比较。本文还讨论了全尺寸超导腔的设计步骤。
To make the light sources compact and energy efficient, an energy recovery Superconducting RF LINAC can be used. We suggest a dual-axis, asymmetric cavity instead of conventional single axis, symmetric cavity configurations to generate average electron beam currents above 1 A, while still avoiding development of the beam breakup instability (BBU). The use of an asymmetric cavity allows one to increase the start current of HOMs participating in BBU instability development, as well as to break the positive feedback, resulting in the capability of a high average current electron beam to be driven without loss through the system. In this work, the results of experimental studies of an asymmetric cavity are presented and compared with theoretical predictions. The following steps toward design of a full-scale superconducting cavity are also discussed.
