Observation of electron cyclotron harmonic emissions due to electrostatic instabilities in mirror-confined plasma

open access: yesPhysical Review Research, 2020
Electron cyclotron instabilities are of fundamental importance in space and laboratory plasmas having nonthermal electron distribution functions. Observations are reported of electromagnetic emissions at electron cyclotron harmonics in a mirror-confined ...

Microstructure formation in radially counterstreaming electron flows

open access: yesNew Journal of Physics, 2021
A theoretical model is developed to describe the formation of microstructures due to plasma streaming instabilities in radially convergent geometries. Microstructures in the form of radial spokes are found experimentally in laser wakefield accelerators ...

Proton Temperature Anisotropy within the Interplanetary Coronal Mass Ejections Sheath at 1 au

open access: yesThe Astrophysical Journal Letters, 2023
The sheath plasma of interplanetary coronal mass ejections (ICMEs) is highly compressed, heated, turbulent, and magnetically intense relative to the ambient solar wind.

Theory of coupled resistive drift and resistive drift ballooning instabilities in fusion plasma

open access: yesHeliyon, 2021
Drift wave instabilities (DWI) associated with the two-fluid dynamics seems to be responsible for anomalous transport in modern day tokamaks. Ballooning instabilities tend to exchange flux tubes of different pressure, resulting in convective transport ...

Helical mode localization and mode locking of ideal MHD instabilities in magnetically perturbed tokamak plasmas

open access: yesNuclear Fusion, 2023
In H-mode tokamak plasmas, the achievable pressure-gradient is limited by type-I Edge Localized Modes (ELMs), which are projected to cause severe damage to future fusion devices.

Theory of Fluid Instabilities in Partially Ionized Plasmas: An Overview

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Partially ionized plasmas (PIP) are essential constituents of many astrophysical environments, including the solar atmosphere, the interstellar medium, molecular clouds, accretion disks, planet ionospheres, cometary tails, etc., where the ionization ...

Perturbative analysis of low-frequency instabilities in high-field ST40 experiments

open access: yesNuclear Fusion, 2023
Linear and nonlinear perturbative analyses of low-frequency instabilities are presented for ST40 spherical torus high field plasmas, with simultaneous neutral beam heating due to two tangential sources at 25 keV and 55 keV.
