  1. 1. Controlled Trapping in Laser Wakefield Accelerators

    Författare :Martin Hansson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser; Wakefield; Acceleration; Trapping; Fysicumarkivet A:2016:Hansson;

    Sammanfattning : Experimental studies of laser-driven acceleration of charged particles, in particular electrons and protons, are described in this dissertation. Tightly focused femtosecond laser pulses with intensities exceeding 1018 W/cm2 were used to accelerate charged particles to high energies over distances of a few millimeters. LÄS MER
