Generation of quasi-perpendicular collisionless shocks by laser-produced plasma with ions of different masses for experimental study of the effects of super-compression of earth's magnetosphere by giant coronal mass ejections

On the base of NASA [1] new approach about important role of Giant plasma releases of so called Coronal Mass Ejections (CME, with kinetic energy up to E_k ∼ 10³⁶ эpg) from the Sun, we have started a series of simulative experiments [2, 3] with Laser-produced Plasma (LP), expanding into magnetized Background Plasma (BP) to generate laboratory Quasi-Perpendicular collisionless Shocks (Q-PS) by LP-piston for the first time. As a result of such experimental scenario, with the LP-model of CME and Q-PS as interplanetary Collisionless Shock Wave (CSW, observed ahead of super-Alfvenic CME), we did a first comparative study of a «quasi-stationary» model of magnetosphere (by BP, overflowing magnetic dipole μ) with its compressed form after LP formation and following Q-PS generation in BP. During the first set [3] of such experiment MagnetoPause-Shock (MPS), we had measured a maximal additional (due to Q-PS) compression near twice of the total (and «global» quasi-uniform) magnetic field B_i inside of MP. Here we could present and discuss some specific experimental features of these B_i-fields and both their models and distributions. Additional attention was done to the important collisionless processes of the Q-PS generation, especially in the given case of the different mass (m/z) of ions in LP-piston. For the last purpose a new data on the dynamics of such ions (H⁺ and C⁺ⁿ) were presented including data of 2D and 3D calculations by Hybrid models with PIC (Particles In Cells) description of all ions.
