Impact Of Stimulated Raman Scattering on ICF in Density Rippled Magnetized Plasma

ORAL

Abstract

In inertial confinement fusion, the development of stimulated Raman scattering is observed in the presence of an azimuthal magnetic field and a density rippling plasma. The Gaussian laser beam traveling through a density rippled plasma is amplified by forward Raman scattering in the presence of an azimuthal magnetic field, resulting in two radially localized electromagnetic sideband waves and a lower hybrid wave. The nonlocal effect generated by the azimuthal magnetic field decreases the nonlocal contact area. As a result, the growth rate in the presence of density rippling magnetized plasma limits the probability of plasma pre-heating in ICF.
