Nonlocal Electron-Energy Transport in Inertial-Fusion Laser Interaction Conditions

Correct modeling of the electron-energy transport is essential for inertial confinement fusion targetdesign. Various transport models have been proposed in order to extend the validity of a hydrodynamical description into weakly collisional regimes, taking into account the nonlocality of the electron transport combined with the effects of self-generated magnetic fields. We have carried out new experiments designed to be highly sensitive to the modeling of the heat flow on the Ligne d'Intégration Laser facility, the prototype of the Laser Megajoule
