Investigation of Turbulent Transport in Non-Stabilized Plasma at the Edge of the GOLEM Tokamak

Plasma turbulent transport was investigated at the edge of the GOLEM tokamak. For this purpose, ion saturation current fluctuations were measured by means of Langmuir probes. Plasma stabilization was not activated during the discharges under study. Non-Gaussian behavior is observed, which indicates the presence of coherent structures. Study of the radial dependence of statistical and temporal characteristics of fluctuations allows to conclude that non-elongated blob-like structures with comparable radial and poloidal size should govern the plasma transport at the edge of the GOLEM tokamak.

Ion-Sound Waves in UHF Discharge Plasma Injected in Open Magnetic Trap

We investigate in stationary regime on the linear plasma device OMT-2 the methods of plasma heating by electromagnetic waves, interaction of electromagnetic waves with magnetoactive plasma and plasma turbulence and transport processes in the trap. We use ultra-high frequency (UHF) contactless method to fill the open magnetic trap by plasma. We have proposed new method of open magnetic trap filling with plasma. Namely, plasma is injected in the trap along the magnetic field from independent stationary UHF source where plasma is formed in ECR regime. In this paper we present the results of investigation of magnetic trap filling by plasma and the results of investigation of plasma low frequency (LF) oscillation in the trap.
