建立了储存环快循环离子束的锥形冷却理论。我们描述了这种冷却方案的基本原理，该方案通过径向位置相关的纵向动量冷却，有效地产生横向和纵向冷却，强调它可能是最有前途的方式束结晶。分析评估冷却速率以研究理想操作条件。本文讨论了冷却力锥形因子的物理意义，并给出了如何确定其最佳值。分子动力学的应用证明了本理论的有效性。{版权} {美国物理学会}
A theory of tapered cooling for fast circulating ion beams in a storage ring is constructed. We describe the fundamentals of this cooling scheme, a scheme that effectively yields both transverse and longitudinal cooling through radial-position-dependent longitudinal momentum cooling, emphasizing that it might be the most promising way to beam crystallization. The cooling rates are analytically evaluated to study the ideal operating condition. We discuss the physical implication of the tapering factor of the cooling force, and show how to determine its optimum value. Molecular dynamics is employed to demonstrate the validity of the present theory. {copyright} {ital 1998} {ital The American Physical Society}
