Quasi-linear electron acceleration in a driven plasma wave
نویسندگان
چکیده
Saturation of the electron plasma wave amplitude exited by a spatially localized driver and the electron acceleration are studied by means of numerical simulations. The model consists of the Zakharov equations for the electron plasma and ion acoustic waves coupled to the quasi-linear equation for the electron distribution function. The saturation levels of both electron plasma and ion acoustic waves and the number and energy of hot electrons are studied in function of the driver wave number and amplitude and the size of the excitation region. A correlation between the onset of the strong Langmuir turbulence and the efficient electron heating is discussed.

Plasma Wave Acceleration of Electron in Bubble Regime in Presence of a Planar Wiggler
The plasma wave acceleration of electron in the bubble regime is investigated in a new configuration containing a planar wiggler. The space-charge field of the laser-created ion channel can focuse and stabilize the electron trajectory to guide it toward the acceleration region. The high-gradient plasma wave field can resonantly accelerate the trapped electron to higher energies in the presence ...

One of the interesting Laser-Plasma phenomena, when the laser power is high and ultra intense, is the generation of large amplitude plasma waves (Wakefield) and electron acceleration. An intense electromagnetic laser pulse can create plasma oscillations through the action of the nonlinear pondermotive force. electrons trapped in the wake can be accelerated to high energies, more than 1 TW. Of t...

متن کاملIntroduction to Plasma Accelerators : the Basics
In this article, we concentrate on the basic physics of relativistic plasma wave accelerators. The generation of relativistic plasma waves by intense lasers or electron beams in low-density plasmas is important in the quest for producing ultra-high acceleration gradients for accelerators. A number of methods are being pursued vigorously to achieve ultra-high acceleration gradients using various...
