In experiments, the feasibility was demonstrated of generating multi-MeV electrons in a form of a collimated beam utilizing a table-top laser system delivering 200 fs pulses with PL=1.2 TW and 10 Hz capability. The method uses the process of relativistic self-channeling in a high-density gas jet producing electron densities in the range of 3×1019–6×1020 cm−3. In a thorough investigation, angularly resolved and absolutely calibrated electron spectra were measured and their dependence on the… CONTINUE READING
