H– and D– sources for fusion, accelerators and other applications

Inductive RF drivers for neutral beam injectors at BINP



Primary authors



In the last decade, a series of high power neutral beam injectors for plasma heating and diagnostics in magnetic fusion experiments has been developed at the Budker Institute of Nuclear Physics. In the injectors, the plasma emitter is produced by inductively coupled radio frequency discharge. With this emitter of difference size, positive ion hydrogen and deuterium beams with energy up to 60 keV and power up to 1.6 MW can be provided. In the last few years, the negative ion sources with the RF drivers have been developed for the injector with higher energies. This paper presents an overview of the design, parameters and performance of the developed plasma drivers.
