Abstract

The optimization of H- extraction from the source is one of the most important issues for developing negative ion sources. The following effects on the total extracted H- current IH- are systematically studied with the 2D3V PIC (Particle in Cell) modeling in a H - volume production source: 1) width of the extraction slit and 2) extraction grid voltage. The PIC modeling results make clear the dependence of IH- on these important parameters. The results also give useful physics understanding about the processes leading to the extraction of H- ions from the source and its optimization.
