Abstract

Large magnetic fields generated during laser-matter interaction at irradiances of ~ 5×1014 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 and found to have an amplitude of ~ 45 T in the outer coronal region. Comparison with magnetohydrodynamic simulations confirms that in this regime the mathTe×mathne source is the main field generation mechanism, while additional terms are negligible.
