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.

    Laser systems designed for fusion research are able to produce a high density of X-ray photons in a metal cavity. Scientists have now proposed that this environment could be used to create matter from light and test a fundamental prediction of quantum electrodynamics.
