Laser Plasma Accelerators
Particle acceleration by relativistic electron plasma waves generated by intense lasers has been demonstrated in a number of experiments by various mechanisms. Accelerating fields as high as 1 GeV=cm, with electrons accelerated to about 100MeV in millimetre distances have been achieved. These fields produced by intense lasers in plasmas are the largest ever produced in laboratory experiments. T...
متن کاملAngular-momentum evolution in laser-plasma accelerators.
The transverse properties of an electron beam are characterized by two quantities, the emittance which indicates the electron beam extent in the phase space and the angular momentum which allows for nonplanar electron trajectories. Whereas the emittance of electron beams produced in a laser-plasma accelerator has been measured in several experiments, their angular momentum has been scarcely stu...
متن کاملLow-emittance electron bunches from a laser-plasma accelerator measured using single-shot x-ray spectroscopy.
X-ray spectroscopy is used to obtain single-shot information on electron beam emittance in a low-energy-spread 0.5 GeV-class laser-plasma accelerator. Measurements of betatron radiation from 2 to 20 keV used a CCD and single-photon counting techniques. By matching x-ray spectra to betatron radiation models, the electron bunch radius inside the plasma is estimated to be ~0.1 μm. Combining this w...
متن کاملLaser-Plasma Accelerators: A Status Report
In this paper, the status of the Laser-Plasma Accelerator field within the Advanced Accelerator Concepts area of research is reviewed. In particular, I review the status of the Plasma Beat Wave Acceleration (PBWA) scheme, the SelfModulated, Laser-Wake Field Acceleration (SMLWFA) scheme and the Laser-Wake Field Acceleration (LWFA) scheme. In all these three schemes, charged particles are acceler...
متن کاملLaser plasma accelerators: status and applications
Compact accelerators based on laser plasma cavities, which support hundreds of GV/ m electric field [1], deliver today electron beam with unique parameters. In 2004 quasi monoenergetic electron beams have been produced in the bubble regime [2] by focusing intense laser beam in under-dense plasma targets. This efficient bubble regime of acceleration is now currently working in many laboratories ...
