HIRFL-CSRm纵向随机冷却-槽形滤波冷却模拟研究
Stochastic momentum cooling with a notch filter at the HIRFL-CSRm
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.
