Positron acceleration in plasma waves driven by non-neutral fireball beams

Resonantly laser-driven plasma waves for electron acceleration.

Dynamics of electron acceleration in laser-driven wakefields: Acceleration limits and asymmetric plasma waves

The experiments presented in this thesis study several aspects of electron acceleration in a laser-driven plasma wave. High-intensity lasers can efficiently drive a plasma wave that sustains electric fields on the order of 100 GV/m. Electrons that are trapped in this plasma wave can be accelerated to GeV-scale energies. As the accelerating fields in this scheme are 3 − 4 orders of magnitude hig...

Plasma waves driven by gravitational waves in an expanding universe

In a Friedmann-Robertson-Walker (FRW) cosmological model with zero spatial curvature, we consider the interaction of the gravitational waves with the plasma in the presence of a weak magnetic field. Using the relativistic hydromagnetic equations it is verified that large amplitude magnetosonic waves are excited, assuming that both, the gravitational field and the weak magnetic field do not brea...

Linear and Nonlinear Dust Acoustic Waves in Quantum Dusty Electron-Positron-Ion Plasma

The behavior of linear and nonlinear dust acoustic waves (DAWs) in an unmagnetized plasma including inertialess electrons and positrons, ions, and mobile positive/negative dust grains are studied. Reductive perturbation method is employed for small and finite amplitude DAWs. To investigate the solitary waves, the Korteweg–de Vries (KdV) equation is derived and the solution is presented. B...

Proton Acceleration in Plasma Waves Produced by Backward Raman Scattering

This paper proposes a new method of proton acceleration. A slow plasma wave produced by backward Raman scattering captures slow protons injected. A density gradient of a plasma enables the wave phase velocity to increase as the proton test beams are accelerated. A proof-of-principle experiment is proposed using a T laser and test beams from a Van de Graaff accelerator, in which a 500mJ laser wi...
