Abstract In the recent experiment on HT-6M tokamak, an improved ohmic confinement phase has been observed after application of the edge multi-pulse turbulent heating, and variance of plasma current ΔIp/Ip is about 14-20%;. The improved edge plasma confinement phase is characterized by (a) increased average electron density Ne and electron temperature Te; (b) reduced Hα radiation from the edge; (c) steeper density and temperature profiles at the edge; (d) a more negative radial electric field over a region of ~ 5mm deep inside the limiter; (e) a deeper electrostatic potential well at the edge; ( f ) reduced magnetic fluctuations at the edge.
