Microstructure formation in radially counterstreaming electron flows
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
The sheath plasma of interplanetary coronal mass ejections (ICMEs) is highly compressed, heated, turbulent, and magnetically intense relative to the ambient solar wind.

Quasi-periodical kinetic instabilities in minimum-B confined plasma
We present the results of an experimental investigation of quasi-periodical kinetic instabilities exhibited by magnetically confined electron cyclotron resonance heated plasmas.

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

Theory of Fluid Instabilities in Partially Ionized Plasmas: An Overview
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
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.
