  4. 2. Development and Applications of a Laser-Wakefield X-ray Source (updated)

    Author : Isabel Gallardo Gonzalez; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; laser-wakefield acceleration; betatron radiation; ionization-induced trapping; direct laser acceleration; laser-wakefield merging; warm dense matter; phase-contract imaging;

    Abstract : In laser-wakefield acceleration (LWFA), a femtosecond laser pulse is tightly focused in a gas to intensities exceeding 1018 W/cm2 . The laser radiation ionizes the medium and excites a plasma wave that travels behind the laser pulse. READ MORE
