Magnetic field measurements in laser-produced plasmasvia proton deflectometry
Large magnetic fields generated during laser-matter interaction at irradiances of ∼ 5 × 10 14 W cm − 2 have been measured using a deflectometry technique employing MeV laser-accelerated protons. Azimuthal magnetic fields were identified unambiguously via a characteristic proton deflection pattern...
