Abstract :
Two possible methods of optically injecting electrons into a plasma accelerator are the self-modulated laser wakefield accelerator (SMLWFA) and laser ionization and ponderomotive acceleration (LIPA). A magnetic selection scheme is proposed to select a narrow band of energies from the intrinsically broad beam produced by the SML- WFA. The scheme is analyzed using 2D particle-in-cell (PIC) simulations and 3D ray tracing. The effects of space charge on the ideal LIPA distribution are examined using full 3D PIC simulations.
