Title: Quenching of the nonlocal electron heat transport by large external magnetic fields in a laser produced plasma measured with imaging Thomson scattering

Abstract

We present a direct measurement of the quenching of nonlocal heat transport in a laser produced plasma by high external magnetic fields. Temporally resolved measurements of the electron temperature profile transverse to a high power laser beam were obtained using imaging Thomson scattering. The results are simulated with the 2D hydrodynamic code LASNEX with a recently included magnetic field model that self-consistently evolves the fields in the plasma.
