| Popis: | 106 One of the fundamental factors in the universe is collisionless shocks. Collisionless shocks have been observed in laser-produced plasma. To obtain the shock Mach number, we need to know the shock velocity and upstream sound velocity. By irradiating a solid target with the high-power laser pulse, we produced laser-produced plasma in a presence of an ambient plasma. We observed temporal and spatial plasma Evolution with global images. The local temperature, density, and velocity of electrons and ions are obtained by collective Thomson scattering(CTS) system. From local temperature and density, we can understand the upstream sound velocity and obtain the shock Mach number. |
