Coupled Ray-Tracing and Fokker-Planck EBW Modeling for Spherical Tokamaks
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 employ...
متن کاملAdvanced Modeling of Cyclotron Wave Heating and Current Drive in Toroidal Plasmas Based on Integro-Differential Full Wave Analysis
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. Th...
متن کاملElectron Bernstein Wave Experiment on the Madison Symmetric Torus
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...
متن کاملElectron Bernstein Wave Studies: Emission and Absorption with Nonthermal Distributions; Current Drive; Delta-F Particle in Cell Simulations
Electron Bernstein waves (EBW) are suitable for heating, current drive, and radiation temperature measurements of overdense plasma, ωpe>>ωce , in spherical torus devices. In NSTX, design of a multi-megawatt EBW current drive system is supported by experimental measurements and computations of obliquely viewing, dual-polarization EBW emission (EBE) radiometry. Efficient EBW coupling, 80±20% at 1...
متن کاملNew Solutions for Fokker-Plank Equation of Special Stochastic Process via Lie Point Symmetries
In this paper Lie symmetry analysis is applied in order to find new solutions for Fokker Plank equation of Ornstein-Uhlenbeck process. This analysis classifies the solutions format of the Fokker Plank equation by using the Lie algebra of the symmetries of our considered stochastic process.
