Plasma Neutralization Models for Intense Ion Beam Transport in Plasma

Plasma neutralization of an intense ion pulse is of interest for many applications, including plasma lenses, heavy ion fusion, cosmic ray propagation, etc. An analytical electron fluid model has been developed based on the assumption of long charge bunches (lb>>rb). Theoretical predictions are compared with the results of calculations utilizing a particle-in-cell (PIC) code. The cold electron f...

Nonlinear Wave Dynamics In Two-Temperature Electron-Positron-Ion Plasma

The hot electron-positron unmagnetized plasma with small fraction of cold electron-ion plasma is investigated. The modulational interactions of the electromagnetic waves and the electron-sound waves are studied. The possibility of soliton formation is investigated.

Wave Phenomena in a Double Plasma Experiment

A double plasma device consists of two plasma volumes, electrically separated by a conducting grid and biased to different plasma potentials. By manipulating the potential difference, a controlled plasma flow from one volume into the other can be generated. With the help of a harmonically modulated potential difference, plasma waves can be excited. Using different modulation frequencies allows ...

Reactive - Medium Instability of the Space Charge Wave of Ion Beam in a Plasma Toshitaka

The mesh-excited space charge wave of ion beam is observed to be amplified in a plasma, as the result of the reactivemedium instability. The amplification factor has the maximum value at the frequency corresponding to the synchronization condition between the beam wave and the lower hybrid wave mode of plasma, and then, an appreciable deceleration of beam is expected from the observation of the...
