LASER DRIVEN ELECTRON ACCELERATION TO GeV ENERGIES IN PLASMA CHANNELS

چکیده
This paper presents a brief discussion of ultra-short laser pulse propagation and laser wakefield acceleration in plasma channels. An envelope equation for the perturbed laser beam radius is given, including finite-pulse length and nonlinear effects. Angular distribution of electrons generated by the process of laser ionization and ponderomotive acceleration (LIPA) is also discussed. An example of laser wakefield acceleration to electron energies greater than 1.2 GeV in a preformed plasma channel is described.

Stable laser-pulse propagation in plasma channels for GeV electron acceleration
To achieve multi-GeV electron energies in the laser wakefield accelerator (LWFA) it is necessary to propagate an intense laser pulse long distances in plasma without disruption. A 3D envelope equation for a laser pulse in a tapered plasma channel is derived, which includes wakefields and relativistic and nonparaxial effects, such as finite pulse length and group velocity dispersion. It is shown...

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 کاملGeV electron beams from a centimeter-scale channel guided laser wakefield accelerator
Laser wakefield accelerators can produce electric fields of order 10–100 GV/m, suitable for acceleration of electrons to relativistic energies. The wakefields are excited by a relativistically intense laser pulse propagating through a plasma and have a phase velocity determined by the group velocity of the light pulse. Two important effects that can limit the acceleration distance and hence the...
متن کاملPlasma 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 ...

In this paper, the influence of initial momentum and the injection angle of electron in to the magnetized plasma in a laser wake-field accelerator have been studied.It has been seen that the use of external magnetic field in the opposite direction of laser pulse propagation leads to an increase in the wake-field amplitude and a decrease in laser pulse group velocity in comparison to the use of ...
