Abstract

Collisionless shocks play important roles for generating high energy particles in outer space. However, detailed mechanisms of collisionless shock formation are not fully understood. 1 In order to clarify physical mechanisms of magnetized collisionless shock formation, we have conducted laboratory experiments using high-power Gekko XII HIPER laser system at Osaka University. To generate the magnetized shock, a vacuum chamber is filled with 5 Torr of N 2 gas with an external magnetic field of several T, and a magnetized N plasma is produced via radiation from the laser-irradiated Al target. However, the discharge voltage for driving the magnetic field is limited to a few kV by Paschen's law. 2 In this study, we developed a magnetic field generator which can apply the magnetic field of several T in N 2 gas with gas pressure of 5 Torr.
