ABSTRACT
The experimental demonstration of the formation a strong electrostatic (ES) collisionless shock has been carried out with high-speed counterstreaming plasmas, produced by high-power laser irradiation, without external magnetic field. nearly four times density jump observed in experiment shows high Mach-number shock. This large is attributed to compression downstream plasma momentum transfer ion reflection upstream plasma. Particle-in-cell (PIC) simulation production ES interaction two slabs different temperatures and densities, as pointed Sorasio et al. [Phys. Rev. Lett. 96, 045005 (2006)]. It speculated that discontinuity balanced incoming reflected ions predominant pressure electrons PIC simulation.
