Laboratory Scale Experiments for Collisionless Shock Generated by Taper-Cone-Shaped Plasma Focus Device

To understand the behavior of astrophysical phenomena, laboratory scale experiments with well-defined behaviors are required. Collisionless shock phenomena have unclear mechanism such as energy dissipation process and generation of highly energetic particles. To generate the collisionless shock in the laboratory scale experiments, Drake, et al. [1] has considered the required conditions, which depend on the magnetic flux density and the shock velocity. To obtain the collisionless shock, the hypersonic plasma flow generated by a taper-cone-shaped plasma focus device is proposed to evaluate in these shocks.
