High-power laser experiment forming a supercritical collisionless shock in a magnetized uniform plasma at rest

Kavli Affiliate: T. Higuchi | First 5 Authors: Ryo Yamazaki, S. Matsukiyo, T. Morita, S. J. Tanaka, T. Umeda | Summary: We present a new experimental method to generate quasi-perpendicular supercritical magnetized collisionless shocks. In our experiment, ambient nitrogen (N) plasma is at rest and well-magnetized, and it has uniform mass density. The plasma is […]
