代替典型的平光束，一些同步加速器光用户更喜欢圆光束，即，具有相等的水平和垂直发射度，由于各种原因（例如，简化的光学器件、被丢弃的光子的较小部分、光子和电子束之间的更好的相空间匹配）。几个未来的升级储存环，如APS-U，ALS-U和SLS-2目前计划在圆束模式下运行。我们报告我们的光束研究结果，在NSLS-II的圆形光束驱动线性差分耦合共振。
Instead of typical flat beam, some synchrotron light users prefer round beam, i.e., with equal horizontal and vertical emittance, for various reasons (e.g., simplified optics, smaller fraction of photons getting discarded, better phase space match between photon and e-beam). Several future upgrade storage rings such as APS-U, ALS-U, and SLS-2 currently plan to operate in round beam mode. We report our beam study results on round beam operating at NSLS-II by driving linear difference coupling resonance.
