Abstract

We investigate collective Thomson scattering (CTS) in two-stream non-equilibrium plasmas analytically, numerically, and experimentally. In laboratory astrophysics, CTS is a unique tool to obtain local plasma diagnostics. While the standard CTS theory assumes plasmas to be linear, stationary, isotropic, and equilibrium, they are often nonlinear, non-stationary, anisotropic, and non-equilibrium in high energy phenomena relevant to laboratory astrophysics. We theoretically calculate and numerically simulate the CTS spectra in two-stream plasmas as a typical example of a non-equilibrium system in space and astrophysical plasmas. The simulation results show the feasibility to diagnose two-stream instability directly via CTS measurements. To confirm the non-equilibrium CTS analysis, we have developed an experimental system with a high repetition rate tabletop laser for laboratory astrophysics.
