Effect of target structure on the magnetic field generation of cylindrical targets in a two-laser system
Abstract
High magnetic fields can be applied to laboratory astrophysics and inertial confinement fusion, among other fields. However, generating high magnetic fields is challenging. Microtube implosion (MTI) is a scheme proposed to amplify a seed magnetic field several orders of magnitude higher. We used 2D EPOCH simulations to explore the effects of using hollow and coated targets in the generation and amplification of the magnetic fields. The results show that MT-order magnetic fields can be generated using a two-laser setup instead of the conventional four-laser setup. Additionally, the gold-coated cylindrical foam targets can generate MT-order magnetic fields even without a seed.
