Abstract Perturbative transport experiment was performed in the HL-2A tokamak. Plasma current and background density were fixed at 170kA and 1.4×1019m-3, while neutral beam injection (NBI) heating power varied... from 400kW to 1MW. Plasma density was modulated by supersonic molecular beam injection (SMBI). Density profile and fluctuation were measured with a fast sweeping Q-band frequency modulated continuous wave (FMCW) reflectometer with the temporal resolution as high as 6μs, which covered a normalized radius range of ρ=0.75~1. Spatiotemporal behaviors of radial profiles of density and density gradient were observed. Particle diffusivity and pinch velocity were evaluated by fitting the phase and amplitude profile of density perturbation. In order to confirm whether the particle transport in HL-2A is diffusive, the relations between particle flux and density gradient were also studied.show more
