Self-modulated wakefield acceleration in a centimetre self-guiding channel

Abstract:

Self-modulated wakefield acceleration was investigated at densities down to ∼4 ×10 18 cm -3 by propagating the 50 TW 300 fs LULI laser in helium gas jets at lengths up to 1 cm. Long interaction lengths were achieved by closer matching of the initial focal spot size to the matched spot size for these densities. Electrons with energies extending to 180 MeV were observed in broad energy spectra which show some evidence for non-Maxwellian features at high energy. Two-dimensional PIC simulations i...
