“…The investigation of the dynamics of strongly magnetized high-energy-density (HED) plasmas is a topic that has been recently the subject of significant effort by many groups. Permitted by the advent of new experimental facilities capable of developing strong magnetic fields [1][2][3], such investigations have led to major progress in diverse fields such as laboratory astrophysics [4][5][6][7][8][9][10][11] or inertial confinement fusion (ICF). In ICF, it has been realized that, by constraining the ion trajectories in the compressed core, and thus increasing their collision rate, magnetization increases the fuel ion temperature [12].…”

We analyze, using experiments and 3D MHD numerical simulations, the dynamic and radiative properties of a plasma ablated by a laser (1 ns, 10$$^{12}$$ 12 –10$$^{13}$$ 13 W/cm$$^2$$ 2 ) from a solid target as it expands into a homogeneous, strong magnetic field (up to 30 T) that is transverse to its main expansion axis. We find that as early as 2 ns after the start of the expansion, the plasma becomes constrained by the magnetic field. As the magnetic field strength is increased, more plasma is confined close to the target and is heated by magnetic compression. We also observe that after $$\sim 8$$ ∼ 8 ns, the plasma is being overall shaped in a slab, with the plasma being compressed perpendicularly to the magnetic field, and being extended along the magnetic field direction. This dense slab rapidly expands into vacuum; however, it contains only $$\sim 2\%$$ ∼ 2 % of the total plasma. As a result of the higher density and increased heating of the plasma confined against the laser-irradiated solid target, there is a net enhancement of the total X-ray emissivity induced by the magnetization.

“…According to the X-ray images, MR occurred both between fields of the plasma bubbles and field of the permanent magnet. The reconnection process became more violent as the field of magnet strengthened, where the mustache-like region appeared when the field strength changed from null to 4000 G. This experiment is believed to be helpful to understand the dynamic phenomena when solar wind interacts with the Earth’s magnetosphere [71] .…”

Laser-driven magnetic reconnection (LDMR) occurring with self-generated B fields has been experimentally and theoretically studied extensively, where strong B fields of more than megagauss are spontaneously generated in high-power laser–plasma interactions, which are located on the target surface and produced by non-parallel temperature and density gradients of expanding plasmas. For properties of the short-lived and strong B fields in laser plasmas, LDMR opened up a new territory in a parameter regime that has never been exploited before. Here we review the recent results of LDMR taking place in both high and low plasma beta environments. We aim to understand the basic physics processes of magnetic reconnection, such as particle accelerations, scale of the diffusion region, and guide field effects. Some applications of experimental results are also given especially for space and solar plasmas.

“…The process of MR has been studied in detail by dedicated magnetic-driven experiments [16] . Based on the quasi-steady state of the self-generated magnetic fields in laser plasmas, we reconstruct the topology of MR and model the loop-top x-ray source [7] , the interaction of solar wind with dayside magnetosphere [17] in the laboratory by using SG-II laser facility. The two MR processes modeled in laboratory are shown in Figure 2 as follows.…”

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.
