Suprathermal electron production at shock-ignition-relevant conditions characterized by combined methods of x-ray imaging and spectroscopy
Original language description
Generation of suprathermal electrons accompanying interaction of high-intensity lasers with the near-solid density matter represent one of the key issues for realization of alternate schemes of inertial confinement fusion [1]. In the shock ignition approach, a role of hot electrons (hereafter HE) is ambiguous: they contribute to enhancement of the ablation pressure but they may also preheat the pre-compressed targets. The principal experimental information was collected via x-ray diagnostics. Non-Maxwellian electrons strongly affect properties of x-ray emitting plasma systems, the collisional processes result in creation of holes in inner electronic shells of target atoms and their subsequent filling via radiative transitions. In particular, the 2p-1sK-shell fluorescence from a relatively cold target material (usually referred to as K? emission) studied by advanced x-ray methods provides a direct experimental technique for HE investigation.
