title = "Analysis of the double-ion plasma in the extraction region in hydrogen negative ion sources",
abstract = "To understand the plasma characteristics in the extraction region of hydrogen negative ion sources is very important for the optimization of H - extraction from the sources. The profile of plasma density in the extraction region is analyzed with a 2D PIC modeling of the NIFS-R&D H - sources. The simulation results make clear the physics process forming a double-ion plasma layer (which consists of positive H+ and negative H- ions) recently observed in the Cs-seeded experiments of the NIFS-R&D source in the vicinity of the extraction hole and the PG (plasma grid).",
