Practical gyrokinetics

PJ Catto - Journal of Plasma Physics, 2019 - cambridge.org
Thousands of gyrokinetic papers have been published since the introduction of the
gyrokinetic change of variables. The intent here is not to review the field, but rather the goal …

Collisional broadening of nonlinear resonant wave–particle interactions

A quasi-local inhomogeneous dielectric tensor for arbitrary distribution functions

SJ Frank, JC Wright, PT Bonoli - AIP Conference Proceedings, 2023 - pubs.aip.org
Treatments of plasma waves usually assume homogeneity, but the parallel gradients
ubiquitous in plasmas can modify wave propagation and absorption. We derive a quasilocal …

An equation of the quasilinear theory with wide resonance region

YI Kolesnichenko, VV Lutsenko… - Ukrainian journal of …, 2018 - irbis-nbuv.gov.ua
An equation of the quasilinear theory is derived. It is based on the same assumptions as the
well-known equation in [1]. However, it has another form of the quasilinear operator, which …
