چکیده

This paper describes the recent developments in the modeling of the ICRF heating process in the VASIMR plasma using the EMIR code. The latest upgrade of the EMIR model involves a calculation of the parallel electric field component with a warm plasma conductivity model and considers the Doppler shift effect. The code now gives a much more accurate and a more physical solution than in the previous version, but requires a more advanced solver.  2004 Published by Elsevier B.V.

A simulation study of RX-mode waves generation in the equatorial plasmasphere

The generation mechanism of RX-mode waves in the equatorial plasmasphere has not been well understood. The Akebono passing through the storm time geomagnetic equator shows the possibility of the local enhancement of RX-mode waves in association with intense Z-mode waves in the equatorial region. We use the initial parameters inferred from observational data from around the plasma-wave generatio...

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...

بررسی گرمایش الکترونی در برهم‌کنش‌های لیزر - پلاسما

 In this paper, stimulated Raman scattering (SRS) and electron heating in laser plasma propagating along the plasma fusion is investigated by particle-in cell simulation. Applying an external magnetic field to plasma, production of whistler waves and electron heating associated with whistler waves in the direction perpendicular to external magnetic field was observed in this simulation. The pla...

Implementing zero-banana-width quasilinear operator for fast ICRF simulations

Numerical simulations of plasma heating with waves in the ion cyclotron range of frequencies (ICRF) require to iteratively couple a solver for wave propagation in plasmas with a solver of the quasilinear kinetic equation. Among the codes developed for this purpose, the TORIC-SSFPQL package is characterized by its high execution speed. The kinetic code SSFPQL, however, was based on a somewhat si...

Electron Heating by ICRF Mode-Conversion Heating in LHD

Electron heating regime using with radio-frequency waves in the ion cyclotron range of frequencies (ICRF) has been investigated in helical magnetic configuration. Mode-conversion scenario was applied to the LHD plasmas. When the wave frequency is change to be lower than that in the standard ICRF heating (minority ion heating) condition, the resonance layers are moved away to the peripheral regi...
