摘要:Abstract(#br)SMBI (supersonic molecule beam injection) plays an important role in tokamak plasma fuelling, density control and ELM mitigation in magnetic confinement plasma physics, which has been widely used in many tokamaks. The trans_neut module of BOUT++ code is the only larg...

摘要:Abstract(#br)Phase Contrast Imaging (PCI) diagnostic has been developed on HL-2 A tokamak. The chord integral density fluctuations of plasma can be obtained by measuring the phase shift of CO 2 laser which has a wavelength of 10.6 μ m after passing through plasma. The 32-cha...

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:Systematic calibration experiment of Langmuir probe sheath potential coefficient Λ, which is a critical coefficient for estimating plasma sheath potential, has been carried out in the HL-2A tokamak deuterium plasmas. The electron energy probability function (EEPF) shows that...

摘要:Isotope effects on instabilities driven by ion temperature gradient (ITG) and impurities in tokamak plasmas in the presence of tungsten ions are numerically studied. It is revealed that the tungsten ions significantly modify the isotope scaling of the maximum growth rates of...

摘要:The toroidicity-induced Alfven eigenmode (TAE) excited by energetic (fast) ions was first simulated using the GTC code for HL-2A experiments. The simulation results indicate that the fraction of energetic ions is about 3% in the experiments. The critical density of energetic ions...

摘要:Diffraction effects of diagnostic windows and a phase plate are evaluated in sets of phase contrast imaging (PCI) systems on HL-2A tokamak. Results show that wave field of an incident laser with shorter wavelength is less effected by diffraction. The diameter of viewing wind...

摘要:Neutral beam (NB) attenuation and beam emission are important aspects for Beam Emission Spectroscopy diagnostic on magnetic confinement devices. In this article, we present the simulation of beam attenuation and beam emission in typical HL-2A discharge scenarios, i.e. Low mo...

摘要:New electromagnetic micro-instabilities are found in magnetically confined toroidal plasmas with two ion species (main and impurity ions) from gyrokinetic simulations by means of linear analysis with the equilibrium model. The instabilities are induced by impurity ion densit...
