Stochastic cooling of electrons and positrons using their extreme ultraviolet radiation is considered. A few beneficial modifications of a stochastic cooling technique are described—a petaherz-scale bandwidth, ability to apply many uncorrelated corrections to particle offsets in one cooling system, cascade amplified stochastic cooling—all resulting in a simpler and more flexible cooling system producing fast cooling without the amplifier. This approach to cooling electron and positron beams easily outperforms radiation cooling in preparing low-emittance and low-energy-spread beams in moderate-energy storage rings.

EUV光对电子和正电子的随机冷却

考虑使用电子和正电子的极紫外辐射进行随机冷却。描述了随机冷却技术的一些有益改进-皮赫兹级带宽，对一个冷却系统中的粒子偏移应用许多不相关的校正的能力，级联放大的随机冷却-所有这些都导致了产生快速冷却的更简单，更灵活的冷却系统没有放大器。在中等能量存储环中制备低发射率和低能量扩散束时，这种冷却电子束和正电子束的方法很容易胜过辐射冷却。
