| 6 | Experimental platform for the investigation of magnetized-reverse-shock dynamics in the context of POLAR显示文摘The influence of a strong external magnetic field on the collimation of a high Mach number plasma flow and its collision with a solid obstacle is investigated experimentally and numerically. The laser irradiation(I ~ 2 × 10^(14) W · cm^(-2)) of a multilayer target generates a shock wave that produces a rear side plasma expanding flow. Immersed in a homogeneous10 T external magnetic field, this plasma flow propagates in vacuum and impacts an obstacle located a few mm from the main target. A reverse shock is then formed with typical velocities of the order of 15–20 ± 5 km/s. The experimental results are compared with 2 D radiative magnetohydrodynamic simulations using the FLASH code. This platform allows investigating the dynamics of reverse shock, mimicking the processes occurring in a cataclysmic variable of polar type. | B. Albertazzi E. Falize A. Pelka E Brack E Kroll R.
