Collisionless shock generation using high-power laser produced super-sonic plasma jet

点击翻译按钮获取中文摘要

Collisionless shochs are generated in high-speed counter-streaming plasma flows produced by irradiating high-power laser beams of Gekko XII HIPER laser system on a CH double-plane target with 4. 6mm in separation. The plasmas and shocks are diagnosed by shadowgraphy, interferometry, and self-emission measurements using ICCD cameras and streak cameras. Collisionless electrostatic shocks are generated in front of the fist CH plane where laser beams are irradiated. Thomson scattering ion-term measurements provide shock parameters, such as electron and ion temperatures, electron density, and flow velocities, both at the up-and down-stream of a shock.
