ions by using two-dimensional particle-in-cell methodMiyamoto, Kenji*; Okuda, Shin*; Hatayama, Akiyoshi*; Hanada, Masaya
The modeling and analysis of a negative ion source is proceeding by using a 2D particle-in-cell simulation. The effect of the H ion production on the plasma grid (PG) surface is investigated. It is shown that with the increase of H ions per time step, the H ion current density is enhanced, while the electron current density decreases with increasing the H production rate on the PG surface. Theseresults agree well with the experimental results observed in typical negative ion sources. Moreover, it is found that plasma quasi-neutrality is held mainly by both H
and H ions in the bulk plasma.
