Harmonic generation has always been of fundamental interest in the study of the nonlinear
nature of any physical system. In the present study, particle-in-cell simulations have been …

This paper reports on the observation of controlled underdense electron heating for high
heat flux applications in the Prototype Material Plasma Exposure eXperiment. The goal of …

Highly overdense magnetically confined fusion plasmas, such as the Mega Amp Spherical
Tokamak (MAST) Upgrade, cannot easily be heated using conventional electron cyclotron …

Abstract The Stellarator de Costa Rica 1 (SCR-1) is a small modular stellarator that serves
as a valuable research and training tool for plasma magnetic confinement. This study aimed …

We discuss the tunneling of quasi-optical wave beams through the evanescent region near
the plasma cutoff in magnetized plasmas with density fluctuations. A model is proposed that …

We present solutions of the Leontovich±Fock parabolic equation which describe the
structure of a paraxial quasioptical wave beam in a medium with strong spatial …

The plasma generation and heating by microwaves is an important research topic in the field
of controlled nuclear fusion. All modern fusion plasma devices such as Wendelstein 7-X use …

Helical equilibria can be generated by arrangements of planar coils similar to tokamaks, but
without a central solenoid and with the toroidal field (TF) coils tilted with respect to the …

Double mode conversion from ordinary mode O to extraordinary mode X is used to achieve
electron Bernstein wave (EBWs) for the electron cyclotron resonance heating (ECRH). The …
