An experimental investigation of the Buneman instability
… is modified so that a short (200 nsec duration) electric field pulse (maximum strength 650 V/m) is applied to accelerate electrons to a drift velocity vD much larger than the initial thermal velocity VTH. The device has a major radius of 19 cm and a minor radius of 3 cm, and a plasma having …

Electron collisions and internal excitation in stored molecular ion beams
… the role, which the initial internal excitation of a molecular ion can play in electron collisions, and the effect of these collisions on the internal excitation are investigated. Dissociative recombination (DR) and inelastic and super-elastic collisions are studied in the system of He2+. The …

Upgrades to the eSTARlight Monte Carlo Event Generator
The Electron-ion collider (EIC) is a collider under development at Brookhaven National Laboratory, expected to be operational in 2033. An electron-ion collision can produce a range of particles including vector mesons. The eSTARlight Monte Carlo event generator simulates these collisions and …

High-Resolution Electron Collision Spectroscopy with Multicharged Ions in Merged Beams
The Heidelberg ion storage ring TSR is currently the only ring equipped with two independent devices for the collinear merging of a cold electron beam with stored ions. This greatly improves the potential of electron-ion collision experiments, as the ion beam can be cooled with one electron beam, …

Study of High Harmonic Fast Waves Interactions in the Scrape off Layer of NSTX-U
… fast wave (HHFW) heating experiments in the National Spherical Torus Experiment (NSTX) at Princeton Plasma Physics Laboratory (PPPL) have shown that up to 60% of the injected power can be lost in the Scrape-Off Layer (SOL) when the fast wave is able to propagate in front of the antenna [Hosea, …

Extending the dielectric formalism in warm dense matter: collisions, dynamic structure factors, and stopping powers
… K and roughly solid densities. Occupying a region in phase space somewhere between hot, sparse plasmas and cool, condensed matter, WDM conditions exist within astrophysical objects, and are created for fractions of a second in inertial confinement fusion (ICF) and laboratory astrophysics …

Incoherent scatter modeling of Jicamarca radar spectra
… on the modeling of spectral characteristics of electron density irregularities of the topside equatorial ionosphere probed by the Jicamarca Incoherent Scatter Radar (ISR) located near Lima, Peru. The topside equatorial ionosphere is a multi-ion plasma and the spectrum of its electron density …
