Astrophysical collisionless shocks are amazing phenomena in space and astrophysical plasmas, where supersonic flows generate electromagnetic fields through instabilities and particles can be accelerated to high energy cosmic rays. Until now, understanding these micro-processes is still a challenge despite rich astrophysical observation data have been obtained. Laboratory astrophysics, a new route to study the astrophysics, allows us to investigate them at similar extreme physical conditions in laboratory. Here we will review the recent progress of the collisionless shock experiments performed at SG-II laser facility in China. The evolution of the electrostatic shocks and Weibel-type/filamentation instabilities are observed. Inspired by the configurations of the counter-streaming plasma flows, we also carry out a novel plasma collider to generate energetic neutrons relevant to the astrophysical nuclear reactions.

“…Counter-streaming plasmas system is a test bed for studying such phenomena in laboratory [27] . Previous SG-II experiments have successfully generated shock wave using unmagnetized counter-streaming plasmas [28][29][30] . In order to generate magnetized plasmas to study the shock wave driven by the CMEs, we plan to add a kilo-Tesla level magnetic field induced by the capacitor-coil target [18] into the counterstreaming plasmas system.…”

In this paper, the recent studies of laboratory astrophysics with strong magnetic fields in China have been reviewed. On the Shenguang-II laser facility of the National Laboratory on High-Power Lasers and Physics, a laser-driven strong magnetic field up to 200 T has been achieved. The experiment was performed to model the interaction of solar wind with dayside magnetosphere. Also the low beta plasma magnetic reconnection (MR) has been studied. Theoretically, the model has been developed to deal with the atomic structures and processes in strong magnetic field. Also the study of shock wave generation in the magnetized counter-streaming plasmas is introduced.

“…To realize this, two plasmas need to penetrate without collision through each other and magnetic field diagnosis should be avoided at the interface where Biermann battery effect usually dominates [30,31,32]. With such criteria, experiments were conducted in 2011 with the SG II laser facility, and the ion-plasma Weibel filamentation instability was observed with interferometry and shadowgraphy techniques [33,34]. The plasma temperature could be calculated through the measured soft x-ray emission spectra.…”

Abstract. Laser plasmas are capable of creating unique physical conditions with extreme high energy density, which are not only closely relevant to inertial fusion energy studies, but also to laboratory simulation of some astrophysical processes. In this paper, we highlight some recent progress made by our research teams. The first part is about directional hot electron beam generation and transport for fast ignition of inertial confinement fusion, as well as a new scheme of fast ignition by use of a strong external DC magnetic field. The second part concerns laboratory modeling of some astrophysical phenomena, including 1) studies of the topological structure of magnetic reconnection/annihilation that relates closely to geomagnetic substorms, loop-top X-ray source and mass ejection in solar flares, and 2) magnetic field generation and evolution in collisionless shock formation.
