    We report on two instabilities that are associated with inertial fusion, namely the laser filamentation instability and the Weibel instability that can filament the relativistic electron beam in fast ignition. We look at the role collisions have in these instabilities. First we consider the filamentation instability of lasers in high Z plasmas typical of hohlraum targets.

    Figure 1 shows the concept for Weibel mediated shock formation, in the case where the Weibel instabilities are created from a momentum anisotropy in the distribution of the plasma flows, 7 creating localized self-generated magnetic fields. The self-generated magnetic fields trap ions via the Lorenz force, thereby imitating collisions in the usual collisional shocks and leading to collisionless ...

    This has prompted an extensive search to justify these instabilities, which are similar to those of Rayleigh-Taylor and Weibel 24,25 A new study that concentrated on the mechanism of these instabilities was introduced by WAN et al. in 2016. 26 They postulated that the observed instabilities arise from the significant interaction between fast electrons oscillating in the transverse direction ...

The class of Weibel-type instabil-ities [4-6] (including the classical Weibel and current-filamentation instabilities) is one such collective mech-anism that has been proposed to generate a turbulent

    Collective processes in plasmas often induce microinstabilities that play an important role in many space or laboratory plasma environments. Particularly notable is the Weibel-type current filamentation instability, which is believed to drive the creation of collisionless shocks in weakly magnetized astrophysical plasmas. Here, this instability class is studied through interactions of ...
