Penning阱中离子运动及存储条件的研究

Study on ion movement and storage condition in penning ion trap

根据在实验中所采用的Penning离子阱结构及电磁场分布特点,列出阱内离子运动方程并进行求解,对其中各种运动进行详细分析,本文还分析了离子的存储条件.最后对所作的研究进行总结,得到如下结论:阱中离子的运动为简谐振动、回旋运动和漂移运动的叠加,这3种运动是稳定的.

Based on the structure of Penning ion trap adopted in experiment and the distributing character of electromagnetic field, this paper educes ion movement equation and resolves the equation, analyzes in detail ion three kinds of motions and storage condition, finally summarizes the study on ion motion： Ion movement in Penning ion trap is summation of axial oscillation, circular cyclotron motion and circular magnetron drift motion., these movements are stable.
