Infinite-order perturbation theories of Vlasov turbulence are developed to obtain a renormalized formulation of the mode coupling and quasilinear equations for current-driven ion-acoustic turbulence. The renormalized theory eliminates divergence problems from nonlinear electron interactions and predicts an ion acceleration mechanism producing substantial ion tails at t..omega../subp//subi/ approx. 50 from initially cold-ion distributions. Time-dependent numerical solutions of the turbulence equations are presented, and comparisons are drawn from experiments and computer simulation. (AIP)
