Operation of Large RF Driven Negative Ion Sources for Fusion at Pressures below 0.3 Pa

Operation of Large RF Driven Negative Ion Sources for Fusion at Pressures below 0.3 Pa

The large (size: 1 m × 2 m) radio frequency (RF) driven negative ion sources for the neutral beam heating (NBI) systems of the future fusion experiment ITER will be operated at a low filling pressure of 0.3 Pa, in hydrogen or in deuterium. The plasma will be generated by inductively coupling an RF p...
