Abstract

The plasma-based acceleration is an encouraging technique to overcome the limits of the accelerating gradient in the conventional RF acceleration. A plasma accelerator is able to provide accelerating fields up to hundreds of GeV/m, paving the way to accelerate particles to several MeV over a short distance (below the millimetre range). Here the characteristics of preliminary electron beams obtained with the self-injection mechanism produced with the FLAME high-power laser at the SPARC_LAB test facility are shown. In detail, with an energy laser on focus of 1.5 J and a pulse temporal length (FWHM) of 40 fs, we obtained an electron plasma density due to laser ionization of about 6×10¹⁸ cm⁻³, electron energy up to 350 MeV and beam charge in the range (50–100) pC.
