Research Abstract

The research of the confinement properties is the key isssue to produce and control plasmas in fusion devices. The aims of this project are (1) to explore the physics basis which governs the structure of nonequilibrium plasma open to external source (sink) and (2) to obtain the confinement scaling law relevant to such a system.
We consider how the total energy balance and the partition balance are affected by the change of external conditions, such as the external control circult, boundary conditions and the power input of the heating system.
According to the method in thermostatistical physics, we made the physical model, formulated the equations and solved them. One example is shown below.
A theoretical model and computational codes have been developed to analyze ICRF heating processes in tokamaks. By emplying the time scale separation technique, we divide the process into three, 1), 2) and 3). We use 1) global wave equation(Maxwell). 2) Fokker-Planck Eq. and 3) Transport Eq. and combine them in a consistent manner. Nonlocal effects are introduced by solving them with proper boundary conditions. Wave excitation. propagation and absorption, high energy ion generation, thermalization of the absorbed power and the temporal and spatial evolution of plasma paramters are simultaneously analyxed. The confinement characteristics ( confinement time, input power scaling, heat pulse propagation, incomplete thermalization phenomena ) and the MHD stability are examined.
