emission in the hard x-ray (HXR) energy range between 20 and 200 keV during lower hybrid …

A new ray-tracing code named C3PO has been developed to study the propagation of
arbitrary electromagnetic radio-frequency (rf) waves in magnetized toroidal plasmas. Its …

Radio-frequency (rf) waves are a powerful tool for improving the performance and stability of
tokamak plasmas through heating and current drive mechanisms, allowing current density …

The possibility of plasma wave simulation based on the finite element method (FEM) was
explored, and a new full wave simulation code of the lower hybrid (LH) wave, Lower Hybrid …

Progress in experiment and simulation capability in the lower hybrid range of frequencies at
ITER relevant parameters is reviewed. Use of LH power in reactor devices is motivated in …

A review of the LH current drive experiments carried out on the Tore Supra tokamak is
presented. The issues for an effective application of the LH wave at high power in reactor …

A full wave simulation of the lower-hybrid (LH) wave based on the finite element method is
presented. For the LH wave, the most important terms of the dielectric tensor are the cold …

Waves at a frequency close to the lower hybrid (LH) resonance are widely used in tokamaks
for non-inductive current drive. Modelling of LH waves is usually carried out by combining a …

With a new lower hybrid (LH) antenna that will allow us to couple up to 4 MW for 1000 s at a
power density of less than 25 MW m-2, and improved diagnosis capabilities provided by the …

Heating and current drive systems must fulfil several roles in ITER operating scenarios:
heating through the H-mode transition and to ignition; plasma burn control; current drive and …
