Numerical Simulation of the Thomson Scattering Experiment Performed with 0.351μm Laser-Produced Aluminum Plasmas

The evolutions of the electron temperatures of aluminum plasmas produced with 0.351μm laser are simulated by means of one-dimensional hydrodynamic code. The simulations show that the plasma geometry has strong influence on the electron temperature’s evolution while the effect of the flux limiter is not so significant. The simulations are in good agreement with the experiments only at some spatial points. A full comparison between the simulations and experiments indicates that the one-dimensional code is not accurate euough to characterize the laser-produced plasmas. A post-processor code based on the hydro code is developed to generate the streak image of the Thomson scattering spectra. which can be directly compared with the experimental data.
