在小型激光储存环（S-LSR）上进行了相干不稳定性反馈阻尼的束流实验。这种不稳定性会导致束流损失，在电子冷却的束流堆叠过程中，束流的存储电流被限制在600 µA左右。采用静电束流位置监测器（ESBPM）和垂直冲击器的垂直反馈阻尼系统（VFS）被应用于抑制这种束流不稳定性。VFS不仅实现了对垂直相干不稳定性的抑制，而且揭示了反馈阻尼的特性。
A beam test for the feedback damping of a coherent instability at small-laser equipped storage ring (S-LSR) was carried out. The instability caused beam loss, which limited the stored beam current to be about 600 µA during beam stacking with electron cooling. A vertical feedback damping system (VFS) using an electro-static beam position monitor (ESBPM) and a vertical kicker was applied to suppress this beam instability. The VFS realized not only suppressing the vertical coherent instability, but also revealing the characteristics of the feedback damping.
