Abstract
Methods and apparatus for igniting a process plasma within a plasma chamber are provided. One or more self-resonating devices are positioned within a plasma chamber relative to a plasma generation volume within the plasma chamber. The plasma generation volume is defined by the plasma chamber. Each of the self-resonating devices generates an ignition plasma. The ignition plasmas cause a partial ionization of an ignition gas. The partially ionized ignition gas allows for ignition of a process plasma by applying an electric field to the plasma generation volume.
