It is shown by particle-in-cell simulations that a narrow electron beam with high energy and charge density can be generated in a subcritical-density plasma by two consecutive laser pulses. Although the first laser pulse dissipates rapidly. the second pulse can propagate for a long distance in the thin wake channel created by the first pulse and can further accelerate the preaccelerat... https://www.diegojavierfares.com/amazing-price-Kicker-48CDF104-Comp-10-Down-Firing-Loaded-Subwoofer-Enclosure-special-find/
