In this study, hydrogen electron plasma is irradiated on an aluminum plate, and negative hydrogen ions are produced on the plate surface. Hydrogen ionic plasma is maintained near the surface, where a deflection magnetic field is applied using a pair of magnets in the vicinity of the surface. When no magnetic field is applied, ionic plasma is not formed. The interface position between the ionic and the electron plasma depends on the quantity of negative ions produced and the deflection magnetic flux density. The deflection magnetic field that controls the electron flux toward the surface, while maintaining quasi-neutrality, is indispensable for the formation of ionic plasma.

偏转磁场在氢离子等离子体形成中的作用

在这项研究中，氢电子等离子体照射在铝板上，并且在板表面上产生负氢离子。氢离子等离子体保持在表面附近，在该表面附近使用一对磁体在表面附近施加偏转磁场。当不施加磁场时，不会形成离子等离子体。离子和电子等离子体之间的界面位置取决于所产生的负离子的数量和偏转磁通密度。在保持准中性的同时，控制朝向表面的电子通量的偏转磁场对于离子等离子体的形成是必不可少的。
