| 中文摘要 | In this paper, the edge plasma parameters. including the electron temperature (T-e), electron density (n(e),), plasma potential (phi(p)), radial electric field (E-r) and the corresponding fluctuations in the Sino-united spherical tokamak (SUNIST) have been systematically measured using Langmuir probe arrays. The characteristics of the edge electrostatic fluctuations and the turbulence-induced transport are experimentally investigated. The results show that a naturally formed E-r x B-phi poloidal velocity shear layer (VSL) exists near the radial location of the limiter. Wavenumber spectrum analyses show that edge fluctuations have a radial propagation character of the drift wave turbulence, with a characteristic radial phase velocity u(phr) similar to 0.7 kms(-1) in the scrape-off-layer and u(phr) similar to 0.9-1.4kms(-1) at plasma edge, suggesting! that the. edge turbulence may originate from the core and propagate to the edge in an intermittent pattern. A radial profile of the toroidal flow velocity Mach number has been observed whose maximum is just located at the VSL position, which may imply a possible relation between the poloidal shear flow and the toroidal plasma flow in SUNIST. |
