Abstract

The formation of electron internal transport barrier (ITB) and achievement of higher ion temperature in large helical device was discussed. The formation of the electron-ITB was correlated with the neoclassical electron root with a strong radical electric field determined by the neoclassical ambipolar flux. As for the ion temperature, high-power neutral beam injection (NBI) heating of 9 MW had realised a central ion temperature of 5 KeV with neon injection.
