摘要
基于以前的研究结果,采用函数级数展开法,研究了Paul阱中在非理想射频囚禁场作用下、考虑二次谐波φ=U-V1cosΩt-Vscos 2Ωt时囚禁离子运动特性,得到了单个囚禁离子运动Mathieu方程的解析解和z方向离子运动的特征频率(宏运动,微运动)随倍频参数的变化规律。
Based on the former research, the equation of a trapped ion considering double frequency of trap field in Paul trap can be solved exactly by using a function series expansion when the trapping potential is not an ideal instance. With the variety of parameter of double frequency, the laws of the character frequency of z direction (secular motion frequency, micro-motion frequency) are shown.
