Observation of Current-Division Ion Sound Wave in a Turbulently Heated Plasma (THE MACHⅡ)

摘要

Dynamic behaviors of the turbulence are measured in a turbulently heated plasma by microwave scattering method. Scattered signals are observed at the time before the plasma becomes resistive. The phase velocity of the wave increases with time. The value of the phase velocity is found to be consistent with that of the ion sound wave propagating across the magnetic field, when the increase of the phase velocity is interpreted as due to the increase of the electron temperature.
