Abstract

The production of strongly magnetized laser plasmas, of interest for laboratory astrophysics and inertial confinement fusion studies, is presented. This is achieved by coupling a 16 kV pulse-power system. This is achieved by coupling a 16 kV pulse-power system, which generates a magnetic field by means of a split coil, with the ELFIE laser facility at Ecole Polytechnique. In order to influence the plasma dynamics in a significant manner, the system can generate, repetitively and without debris, high amplitude magnetic fields (40 T) in a manner compatible with a high-energy laser environment. A description of the system and preliminary results demonstrating the possibility to magnetically collimate plasma jets are given.

摘要

本文介绍了强磁化激光等离子体的产生，这对于实验室天体物理学和惯性约束聚变研究具有重要意义。这是通过耦合一个16 kV脉冲功率系统来实现的。该系统通过一个分裂线圈产生磁场，并与巴黎综合理工学院的ELFIE激光装置相耦合。为了显著影响等离子体动力学，该系统能够以与高能激光环境兼容的方式重复产生无碎片的高振幅磁场（40 T）。文中给出了该系统的描述以及证明磁准直等离子体射流可能性的初步结果。
