惯性静电约束（IEC）器件源区的离子种类组成对器件中的原子和分子物理过程以及由此产生的快离子能谱和中子产生率起着重要作用。本文提出了IEC器件源区离子组分的零维速率方程模型，并与威斯康星州IEC器件的实验测量结果进行了比较[J. F. Santarius，G. L.库尔钦斯基河P.阿什利等人，融合科学Tech. 47，1238（2005）]。使用离子声波诊断测量的离子种类组成，结果与理论预测吻合良好。理论和实验结果都表明，在源极区，D3+离子占绝大多数。
The ion species composition in the source region of inertial electrostatic confinement (IEC) devices plays an important role in the atomic and molecular physics processes in the device and in the resulting energy spectrum of the fast ions and the neutron production rate. A zero dimensional rate equation model for the ion species composition in the source region of IEC devices is presented and compared with experimental measurements on the Wisconsin IEC device [J. F. Santarius, G. L. Kulcinski, R. P. Ashley et al., Fusion Sci. Tech. 47, 1238 (2005)]. The ion species composition is measured using an ion acoustic wave diagnostic; the results are in good agreement with the theoretical predictions. Both the theory and the experimental results show that D3+ ions are the majority species in the source region.
