Towards large and powerful radio frequency driven negative ion sources for fusion

New Journal of Physics, 2017
The ITER neutral beam system will be equipped with radio-frequency (RF) negative ion sources, based on the IPP Garching prototype source design. Up to 100 kW at 1 MHz is coupled to the RF driver, out of which the plasma expands into the main source ...
