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


The nonlinear evolution of ion acoustic fluctuations in the presence of a uniform electron drift which exceeds the sound speed and electron-ion collisions is investigated using a collisional particle simulation model for parameters relevant to laser-heated plasmas. The results indicate that for the one-dimensional case, strong electron-ion collisionality can lead to a significantly higher saturation level of the fluctuations, which is comparable to the saturation level in the two-dimensional...[Show more]
