Seeded Megagauss Turbulence in Dense Fusion-Target Plasmas

A collision-dominated inhomogeneous plasma seeded with a distribution of impurity grains is calculated to fill out rapidly with random megagauss fields for temperatures of about a kilovolt. Possible applications of this phenomenon (i) to enhance relativistic-electron-beam coupling to low-$Z$ target plasmas, (ii) to influence transport coefficients, or (iii) to localize $\alpha$-particle deposition in a reacting DT plasma are discussed.
