我们一直使用电子回旋共振离子源（ECRIS）的离子束生产，它是理想的，以建立一个通用的ECRIS，可以产生离子的质量/电荷比的范围很宽，例如从几个到几千。我们研究了具有高质量/电荷比的离子的特性，例如，铁内嵌富勒烯的生产，这需要低电压束提取。研究了低引出电压下的离子束引出特性。结果表明，对于不同的离子种类，束流几乎都服从Child-Langmuir定律。由引出电压与偶极磁铁磁场强度平方的关系，可以得到离子源中等离子体的空间电势。结果表明，在低气压和高微波入射功率条件下，离子的电荷态越大，空间电位值越大。同时，用朗缪尔探针测量了等离子体空间电位，并与离子束法进行了比较。用探针法进行了验证，发现其趋势与实验结果一致。
We have been using an electron cyclotron resonance ion source (ECRIS) for ion beam production, and it is desirable to construct a universal ECRIS that can produce ions with a wide range of mass/charge ratios, eg from several to several thousand. We investigated the characteristics of ions with high mass/charge ratios, eg, iron endohedral fullerenes production, which requires low voltage beam extraction. We investigated the characteristics of the ion beam extraction at low extraction voltage. It is found that the beam current almost obeyed the Child-Langmuir law for various ion species. The space potential of the plasma in the ion source can be obtained from the relation between the extraction voltage and the square of the magnetic field strength of the dipole magnet. It is found that space potential values are larger with large charge state of ions, in low gas pressure condition and in high microwave incident power. At the same time, the plasma space potential was measured by using a Langmuir probe and compared with the ion beam method. It is found that same trend is confirmed with probe method.
