摘要
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 currentΔI_(p)/I_(p) is about 14-20%;.The improved edge plasma confinement phase is characterized by(a)increased average electron density N_(e) and electron temperature T_(e);(b)reduced Hαradiation 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.
