Characterization of laser-produced carbon plasmas relevant to laboratory astrophysics
Abstract
Experiments, analytic modeling, and numerical simulations are presented to characterize carbon plasmas produced by high-intensity (109−1013 W cm−2) lasers relevant to experimental laboratory astrophysics. In the large-scale limit, the results agree well with a self-similar isentropic, adiabatic fluid model. Laser-target simulations, however, show small-scale structure in the velocity distribution of different ion species, which is also seen in experiments. These distributions indicate that most of the plasma energy resides in moderate charge states (C+3–C+4), most of the mass resides in the lowest charge states, and the highest charge states move fastest.
