Abstract
The neutral beam injector NBI is one of the main plasma heating methods for nuclear fusion devices For the hot cathode high current ion source the arc current and beam current tends to increase during the beam pulse In order to gets long pulse beam extraction the arc regulation technology is employed The Langmuir probes are installed on the experimental advanced superconducting tokamakNBI ion source to feedback control the arc discharge and beam extraction The experimental results show that the long pulse of 100 s ion beam is extracted with beam energy of 30 keV with arc regulation More the results are presented in this paper
