Initial Plasma Confinement Experiments in Tokamak-Helical Hybrid Device TOKASTAR-2

On The Confinement of a Tokamak Plasma

The goal of this paper is to understand from a mathematical point of view the magnetic confinement of plasmas for fusion. Following Frénod and Sonnendrücker [7], we first use two-scale convergence tools to derive a gyrokinetic system for a plasma submitted to a large magnetic field with a slowly spatially varying intensity. We formally derive from this system a simplified bi-temperature fluid s...

Burning Plasma Simulation and Environmental Assessment of Tokamak, Spherical Tokamak and Helical Reactors

Reference 1-GWe D-T reactors; tokamak TR-1, spherical tokamak ST-1 and helical HR-1 reactors, are designed using PEC (Physics Engineering Cost) code, and thier plasma behaviors with Internal Transport Barrier (ITB) operations are analyzed using TOTAL (Toroidal Transport Analysis Linkage) code, which clarifies the requirement of deep penetration of pellet fueling to realize steady-state advanced...

RF-Heating and Plasma Confinement Studies in HANBIT Mirror Device

HANBIT is a magnetic mirror confinement device. Recently, with almost finishing the first campaign for the basic system development, it started the second campaign for the high-temperature plasma confinement physics study in mirror configuration. Here, we introduce briefly the HANBIT device and report initial physics experiments results on RF-plasma heating and confinement in the simple mirror ...

Divertor Plasma Physics Experiments on the Diii–d Tokamak

DIVERTOR PLASMA PHYSICS EXPERIMENTS ON THE DIII–D TOKAMAK. In this paper we present an overview of the results and conclusions of our most recent divertor physics and development work. Using an array of new divertor diagnostics we have measured the plasma parameters over the entire divertor volume and gained new insights into several divertor physics issues. We present direct experimental evide...
