The present approach relies on the neglect of any significant collective beam-plasma effect 3, as already suggested several times 1, 2, 4, by analytical estimates as well as numerical simulations demonstrating that intense ion beams (E/A 50 MEV) are unlikely to be significantly deflected by Cited by: full array of phenomena associated with HED beam-plasma interactions is not the intent of this report, but the committee believes that the information provided will give the reader some idea of the wealth of phenomena associated with beams in plasmas.

ion motion will be ignored and only the plasma electrons will be considered to play a role in the beam-plasma interaction. Since the E-Layer mean radius is approximately 40 cm, we consider the interaction to occur in a sector of the E-Layer where the beam particles have essentially straight line orbits.

Jul 01,  · Several mechanisms to explain the saturation of the beam plasma instability and the simultaneous broadening of the beam energy distribution function for the case where the beam is cold and weak and the plasma is cold and collision dominated are explored.

(Modified author abstract)Author: Dan Winske. At the later stage of beam-plasma interactions, the ion beams are strongly modulated by the two-stream instability and multiple density spikes are formed in the longitudinal direction.

The formation of these density spikes is shown to result from the excitation of harmonic plasma waves. Unfortunately, this book can't be printed from the OpenBook.

Below is the uncorrected machine-read text. Electron-beam physical vapor deposition, or EBPVD, is a form of physical vapor deposition in which a target anode is bombarded with an electron beam given off by a charged tungsten filament under high vacuum.

The electron beam causes atoms from the target to transform into the gaseous phase. These atoms then precipitate into solid form, coating everything in the vacuum chamber (within line of.

Beam–plasma interactions in a positive ion–negative ion plasma The Physics of Fluids 26 The fluid dispersion relation and most growing modes are predicted to be insensitive to many parameters of the PANIC beam–plasma system, and found to the consistent Book, NRL Plasma Formulary (Naval Research Laboratory, Washington, D.C., Cited by: Innovative Education and Training in high power laser plasmas (PowerLaPs) for plasma physics, high power laser-matter interactions and high energy density physics - Theory and experiments.

These methods also tend to make ion and plasma engines heavy compared to combustion engines, so they are not used for launch from high gravity bodies. Rather they operate where there is already a low-g environment in orbit or away from gravity wells.
