Abstract:
We studied the generation of low emittance high current
mono-energetic beams from plasma waves driven by
ultra-short laser pulses, in view of achieving beam
brightness of interest for FEL applications. We have
studied a regime based on a LWFA plasma driving
scheme on a gas jet modulated in areas of different
densities with sharp density gradients. Simulations carried
out using VORPAL show that, using a properly density
modulated gas jet, it is possible to generate beams at
energies of about 30 MeV with peak currents of 20 kA,
slice transverse emittances as low as 0.3 μm and energy
spread around 0.4 %. This beams break the barrier of 1018
A/(mm.mrad)2 in brightness, opening a new range of
opportunities for FEL applications. An example of FELs
driven by such kind of beams injected into laser
undulators is shown. The system constituted by the
electron beam under the effect of the e.m. undulator has
been named AOFEL (for All Optical Free-Electron
Laser)
