Particle-in-cell simulations of heat flux driven ion acoustic instability

Detering, Frank; Rozmus, F; Brantov, W; Bychenknov, V.Y.; Capjack, C.E.; Sydora, R


The return current instability of ion acoustic waves in a laser heated plasma is studied by means of a collisional particle-in-cell code and theoretical analysis in the regime of nonlocal heat transport. The physical scenario of localized, inverse Bremsstrahlung heating in a single laser hot spot, electron thermal transport, return current of cold electrons, instability of ion acoustic waves, and resulting ion acoustic turbulence are examined in a self-consistent kinetic collisional particle...[Show more]
