摘要:Ion internal transport barriers (iITBs) are first observed in neutral beam injection (NBI) heated plasmas at the HL-2A tokamak. The position of the barrier foot, in the stationary state, coincides with the q = 1 surface within its uncertainty of measurement. iITBs can develo...

摘要:Strong resonant and non-resonant internal kink modes (abbreviated as RKs and NRKs, respectively), which are also called resonant and non-resonant fishbones, are observed on HL-2A tokamak with high-power ECRH + ECCD (or ECRH) and ECRH + ECCD+, respectiv...

摘要:A novel two-laser P olarimeter- I nterferomet er ( PIer ) diagnostic scheme, in which Faraday rotation angle (α F ) and electron density ( n e ) can be simultaneously measured by taking advantage of two lasers and two detectors for each channel, has be...

摘要:Kinetic Alfvén and pressure gradient driven instabilities are very common in magnetized plasmas, both in space and the laboratory. These instabilities will be easily excited by energetic particles (EPs) and/or pressure gradients in present-day fusion and future burning plasm...

摘要:In HL-2A, an inverse sawtooth oscillation is observed with a long-lasting m / n = 1/1 mode during ECRH phase with power deposition inside sawtooth inversion radius (inner-deposited ECRH), while a normal sawtooth instead appears when the ECRH power is deposited outside sawtoo...

摘要:Modulation of turbulent electron temperature fluctuations ( ) and density fluctuations ( ) by an m /n = 1/1 tearing mode island was observed in the core plasma region of the HL-2A tokamak. High spatiotemporal resolution two-dimensional images of show the first evidence that the ...

摘要:We report an experimental result on the stabilization of the energetic–ion driven internal kink mode (ion fishbone) by electron cyclotron resonance heating (ECRH), observed for the first time in a toroidal plasma. The mode asserts itself a resistive branch close to the margi...
