计算机模拟表明,共振吸收的局部各向异性加热驱动了维贝尔样不稳定性,在典型的激光聚变参数下产生了兆赫高斯磁场。磁场可以抑制热输运,使热电子部分各向同性。
Computer simulations present evidence that the localized anisotropic heating from resonant absorption drives a Weibel-like instability that generates megagauss magnetic fields for typical laser-fusion parameters. The magnetic fields can inhibit heat transport and partially isotropize the hot electrons.
