Principle and applications of electron beams produced with laser plasma accelerators

Laser 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 ...

Femtosecond Transversal Deflection of Electron Beams with the Help of Laser Beams and Its Possible Applications

It is shown that the interaction of an electron beam with polarized electromagnetic wave of laser photons propagating in the same direction in a short interaction region results in significant transversal deflection of the electrons which can be used for production of femtosecond electron and synchrotron radiation beams, for chopping the electron beams and construction of laser oscilloscopes me...

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...

Wavefront-sensor-based electron density measurements for laser-plasma accelerators.

Characterization of the electron density in laser produced plasmas is presented using direct wavefront analysis of a probe laser beam. The performance of a laser-driven plasma-wakefield accelerator depends on the plasma wavelength and hence on the electron density. Density measurements using a conventional folded-wave interferometer and using a commercial wavefront sensor are compared for diffe...
