title: Basis of the discharge maintenance in a matrix source of negative hydrogen ions.
abstract: The presented three-dimensional (3D) self-consistent model of a matrix source completed by small-radius planar-coil driven rf discharges in hydrogen is in the scope of the recent research on a new design of the rf sources of negative hydrogen ions for fusion applications. The analysis of the results for the spatial distribution of basic discharge characteristics (electron density and temperature, rf current density and rf field intensity) in the three configurations of the matrix considered aims at conclusions about a manner of rf inductive-mode driving proper for ensuring the same discharge behavior in the gas-discharge tubes of the matrix.
