Coulomb explosion of spherical ion clusters is studied, which are composed of homogeneous two-species light and heavy ions. A simple analytical model is developed to describe the explosion performance in terms of two dimensionless parameters, the charge-over-mass ratio, and the charge density ratio. One-dimensional kinetic numerical model is performed to compare with the analytical model and to evaluate the energy coupling efficiency of quasimonoenergetic ion generation. It is crucial to preform an iso-Coulomb-potential profile of the light ions in the cluster for efficient generation of quasimonoenergetic ions.

研究了由均质轻重离子两种组成的球形离子簇的库仑爆炸。开发了一个简单的分析模型，以二维无量纲参数、电荷质量比和电荷密度比来描述爆炸性能。进行一维动力学数值模型以与解析模型进行比较并评估准单能离子生成的能量耦合效率。为了有效生成准单能离子，在簇中预先形成轻离子的等库仑电势分布至关重要。
