Psfc / Ja - 02 - 18 Symmetries in Dissipation - Free Linear Mode Conversion
نویسنده
چکیده
Linear mode conversions (MC) in loss-free (LF) regions of an inhomogeneous, Vlasov plasma in a magnetic field are shown to obey certain symmetries [1]. These are illustrated and interpreted for situations relevant to plasma heating and/or current drive. INTRODUCTION Consider a one-dimensional (in x) generic propagation and MC situation in an inhomogeneous plasma, with unperturbed (equilibrium) parameters (e.g., density, temperature, and magnetic field) that vary in x, as shown schematically in Figure 1. For homogeneity along B0 = ẑB0(x), Landau and/or Doppler shifted cyclotron resonance absorption for any kz is assumed to occur outside the LF-MCR.

Corrugated waveguide transmission lines are in use to transmit high power mm-wave radiation from gyrotrons to the plasma for electron cyclotron plasma heating in tokamaks such as ITER. The coupling efficiency of the gyrotron output radiation formed as a quasi-Gaussian beam to the waveguide mode is a critical issue. A hyperbolic corrugated horn serves as a converter of the TEM00 Gaussian mode to...

Previous theoretical analysis [1] of mode conversion of fast Alfv6n waves (FAW) to ion-Bernstein waves (IBW) neglected poloidal variations of the fields and magnetic shear. Full-wave codes show incident FAW fields focused into multiple poloidal modes near the ion-ion hybrid resonance (IHR)[2]. A new mode conversion model has been constructed including poloidal wavenumbers and poloidal magnetic ...
متن کاملPsfc/ja-01-32 Emission of Electron Bernstein Waves in Plasmas
it has been shown that, in overdense plasmas of the type encountered in spherical tori, electron Bernstein waves can be excited in a plasma by mode conversion of either an externally launched X mode or an O mode. The electron Bernstein waves are strongly absorbed by electrons in the region where the wave frequency matches the Doppler broadened electron cyclotron resonance frequency or its harmo...
