Abstract
We report on new findings in a laser driven enhanced electron beam generation in the multi MeV energy range at moderate relativistic laser intensities and their applications. In our experiment, an intense sub-picosecond laser pulse propagates through a plasma of a near critical electron density (NCD) and direct laser acceleration (DLA) of electrons takes place. The breakthrough toward high current relativistic electron beams became possible due to application of low density polymer foams of sub-mm thickness. In foams, the NCD-plasma was produced by a mechanism of super-sonic ionization. Compared to NCD-plasmas generated by laser irradiation of conventional foils, the DLA acceleration path in foams was strongly enhanced. Measurements resulted into 11÷13 MeV of the effective electron temperature and up to 100 MeV maximum of the electron energy measured in the laser pulse propagation direction. The growth of the electron energy was accompanied by a strong increase of the number of super-ponderomotive electrons ...
