电子与囚禁离子弹性碰撞中的能量转移
Energy transfer in elastic collisions between electrons and trapped ions
摘要：
被捕获的离子云加热的相互作用与自由电子跨越捕获电位进行了观察。提出并讨论了描述这一过程的模型。所提出的方法预测两种效果：推动和加热的离子的合奏由电子。前者被发现是太弱的观察，但后者进行了实验研究。为了比较实验结果和理论预测，分子动力学模拟的各种离子系综在不同的温度进行，以确定离子云的几何形状和它的温度之间的依赖关系。定义并确定了加热速率系数和电子轰击离子云的温度。发现这两个量之间具有良好的相关性，这与所提出的模型相一致。
英文摘要：
Heating of trapped ion clouds by interactions with free electrons crossing the trapping potential was observed. A model describing such process was proposed and discussed. The presented approach predicts two effects: pushing and heating of the ions' ensemble by electrons. The former was found to be too weak for observation, however the latter was investigated experimentally. For comparison between experimental results and theoretical predictions, molecular dynamics simulations for various ion ensembles in various temperatures were performed to determine dependence between ion cloud geometry and its temperature. A heating rate coefficient was defined and determined together with temperatures of ion clouds bombarded with electrons. Good correlation between the two quantities was found, which agrees with the proposed model.
