| 摘 要： | 通过Fokker Planck方程，对拟在HIRFL-CSRm上建造的纵向槽形滤波器（notch filter）的冷却机理进行了研究，得出了冷却原理及冷却时间的表达式，并对影响冷却时间和冷却效果的因素进行了模拟和讨论，模拟结果表明，噪信比越小，冷却时间越短，冷却效果越好；带宽越宽冷却越快。该研究为具体纵向冷却系统的设计和优化提供了依据。

| Abstract: | The stochastic momentum cooling with a notch filter that will be built on HIRFL-CSRm is described and formulated with Fokker-Planck equation. The square of the standard deviation of energy error and the initial cooling time are obtained. This provides a guide to analysis of experimental data and design of the cooling system, e.g.optimization of the system passband and gain, specification of accuracy of the signal's transmission, etc． |
