标题： Useful formulas for non-magnetized electron cooling

摘要： 低能RHIC电子冷却器（LEReC）的近期成功为基于由RF腔加速的非磁化电子束的高能电子冷却器的发展开辟了道路。此类冷却器中的电子可以具有具有各种不相等的水平、垂直和纵向速度散布的速度分布。在本文中，我们重新审视非磁化冷却中的摩擦力公式，并为不同的极限情况推导出许多有用的表达式。 显示英文摘要

摘要： Recent success of Low Energy RHIC Electron Cooler (LEReC) opened a road for development of high energy electron coolers based on non-magnetized electron bunches accelerated by RF cavities. Electrons in such coolers can have velocity distribution with various unequal horizontal, vertical and longitudinal velocity spreads. In this paper we revisit a formula of friction force in non-magnetized cooling and derive a number of useful expressions for different limiting cases.
