论文摘要
到目前为止，随机冷却仅在微波频率上进行测试和使用。这些随机冷却系统中的大多数都是在没有Schottky带重叠的情况下运行的，从而大大简化了冷却系统的调整，并消除了不同冷却系统之间不需要的耦合。从微波随机冷却到光学随机冷却或相干电子冷却的过渡会通过数量级来增加冷却系统的中心频率，并且如果没有肖特基频段的重叠，就不可能成为冷却系统的操作。在本文中，我们考虑频带重叠如何影响最大冷却速率和最佳增益。
Up to present time the stochastic cooling was only tested and used at the microwave frequencies. Majority of these stochastic cooling systems operate without Schottky band overlap which greatly simplifies tuning of cooling systems and removes unwanted coupling between different cooling systems. A transition from the microwave stochastic cooling to the optical stochastic cooling or to the coherent electron cooling increases the central frequency of cooling systems by orders of magnitude and makes impossible a cooling system operation without overlap of Schottky bands. In this paper we consider how the band overlap affects the maximum cooling rate and the optimal gain.
