摘要：

The physics of the formation and termination of high ion temperature mode (hgh T-i mode) is studied by controlling density profiles and radial electric field. High ion temperature mode is observed for neutral beam heated plasmas in heliatron/torsatron plasmas (Heliotron-E). This high T-i mode plasma is characterized by a peaked ion temperature profile and is associated with a peaked electron density profile produced by neutral beam fuelling with low wall recycling. This high T-i mode is terminated by flattening of the electron density caused either by gas puffing or by second-harmonic ECH (core density 'pump out').
