Coupled Ray-Tracing and Fokker-Planck EBW Modeling for Spherical Tokamaks
نویسندگان
چکیده
The AMR (Antenna—Mode-conversion—Ray-tracing) code [1, 2] has been recently coupled with the LUKE [3] Fokker-Planck code. This modeling suite is capable of complex simulations of electron Bernstein wave (EBW) emission, heating and current drive. We employ these codes to study EBW heating and current drive performance under spherical tokamak (ST) configurations—typical NSTX discharges are employed. EBW parameters, such as frequency, anteima position and direction, are varied and optimized for particular configurations and objectives. In this way, we show the versatility of EBWs.

Numerical Studies and Simulation of the Lower Hybrid Waves Current Drive by using Fokker – Planck Equation in NSST and HT-7 Tokamaks
Recent experiments on the spherical tokamak have discovered the conditions to create a powerful plasma and ensure easy shaping and amplification of stability, high bootstrap current and confinement energy. The spherical tours (ST) fusion energy development path is complementary to the tokamak burning plasma experiment such as NSTX and higher toroidal beta regimes and improves the design of a po...

Self-consistent and accurate modeling of wave-plasma interactions is one of the key issues in producing and sustaining burning plasmas. We have upgraded our full wave component of the integrated modeling code TASK, taking account of the finite gyroradius effects indispensable for correctly describing the absorption of ICRF waves by energetic ions and the behavior of electron Bernstein waves.

A system to heat electrons and possibly drive off-axis field-aligned current is under development on the Madison Symmetric Torus RFP. Staged experiments have reached an input power of 150kW at 3.6GHz and have produced a localized increase in SXR emission during rf injection. This measured emission is consistent with modeling in its location, energy spectrum and dependence on radial diffusion wi...

Overdense plasma heating with electron Bernstein waves (EBWs) is of large importance for fusion, since ultra high density operation is a promising fusion scenario for stellarators and heliotrons. The EBW physics is also important for spherical tokamaks (ST). Here the plasma core is inaccessible for standard ECRH with electromagnetic waves. The EBW driven current could help to stabilize MHD-mode...
