Plasma-based accelerators

Plasma-based accelerators use plasmas to increase the kinetic energy of charged particles such as electrons, protons, and ions. Plasma-based accelerators usually use laser-produced plasmas in which charge neutrality is broken in a localized area. The plasma-based approach enables devices much smaller than conventional particle accelerators.

    A major challenge for achieving useful thermonuclear fusion regimes is heating plasma to reactive temperature conditions. It is demonstrated experimentally how energetic ions, generated via neutral beam injection, can be exploited for this process.

    Shaping particle beams generated from laser-plasma accelerators is challenging. Here the authors demonstrate an all-optical method to structure the accelerated proton beam by modulating and imprinting the spatial laser profile onto the proton beam.

    Laser technology is rapidly developing to the point where pulse power and intensity are expected to reach such levels that new physical processes will be able to be studied for the first time. Using simulation the authors theoretically investigate the generation of high brilliance gamma rays and electron-positron pairs during extreme intense laser interaction with a specific target.
