目前，卫星在空间运行的寿命需要10-15年。氙被用作卫星离子发动机的燃料。发动机低能电子束辐照和溅射存在累积损伤问题。建立100 eV ~ 1 keV低能区离子束溅射产额数据库是一项重要的工作。我们试图通过实验研究低能离子束辐照卫星部件的溅射产额。在辐照实验中，我们使用了电子回旋共振离子源（ECRIS）。在10 kV高压下引出后，束流能量降低到几百eV。发现在几十eV的ECRIS中，等离子体空间势的贡献不可忽略。在ECRIS上测量了工作条件下的等离子体参数和离子束减速特性。结果表明，在低电荷态离子占优势的ECRIS工作条件下，在束流能量约为100 eV时，ECRIS的空间电位效应为10 ~ 20%。
At present it is necessary the satellite lifetime 10-15 years for operating in space. Xenon is used as fuel for ion engines of satellites. There are problems of accumulated damages at irradiation and sputtering by low energy Xe ion from the engine. It is required to construct database of sputtering yield of ion beams in the low energy region from a hundred eV to 1keV. We are trying to investigate experimentally sputtering yield on satellite component by irradiating the low energy Xe q+ ion beams. We use the electron cyclotron resonance ion source (ECRIS) in the irradiation experiments. We decelerate the beam energy to several hundred eV after extraction at high voltage 10kV. It is found we cannot neglect the contribution of the space potential of the plasma in the ECRIS of several tens eV. We measured the plasma parameters and ion beam deceleration characteristics in operating conditions on ECRIS. As the results, it was found in operating ECRIS condition of low charge state ion being dominant that the space potential of the ECRIS has an effect of 10∼ 20% at the beam energy at about 100eV in conducting irradiation experiments on satellite component materials.
