Abstract

This paper presents the goals and some of the results of experiments conducted within the Working Package 10 (Fusion Experimental Programme) of the HiPER Project. These experiments concern the study of the physics connected to "Advanced Ignition Schemes", i.e. the Fast Ignition and the Shock Ignition Approaches to Inertial Fusion. Such schemes are aimed at achieving a higher gain, as compared to the classical approach which is used in NIF, as required for future reactors, and making fusion possible with smaller facilities. In particular, a series of experiments related to Fast Ignition were performed at the RAL (UK) and LULI (France) Laboratories and were addressed to study the propagation of fast electrons (created by a short-pulse ultra-high-intensity beam) in compressed matter, created either by cylindrical implosions or by compression of planar targets by (planar) laser-driven shock waves. A more recent experiment was performed at PALS and investigated the laser-plasma coupling in the 1016 W/cm2 intensity regime of interest for Shock Ignition. © 2011 SPIE.

Abstract

Fast electrons produced by a 10 ps, 160 J laser pulse through laser-compressed plastic cylinders are studied experimentally and numerically in the context of fast ignition. K(alpha)-emission images reveal a collimated or scattered electron beam depending on the initial density and the compression timing. A numerical transport model shows that implosion-driven electrical resistivity gradients induce strong magnetic fields able to guide the electrons. The good agreement with measured beam sizes provides the first experimental evidence for fast-electron magnetic collimation in laser-compressed matter.

Abstract

We report on experimental results of the fast electron transport in compressed plasmas, created by laser-induced shock propagation in both cylindrical and planar geometry. Two experiments were carried out. The first one was based on the compression of a polyimide cylinder filled with foams of three different initial densities (rho(0)). X-ray and proton radiographies of the target during the compression coupled with hydrodynamic simulations show that the obtained core densities and temperatures range from 2 to 11 g/cm(3) and from 30 to 120 eV, respectively. By studying the K-shell fluorescence from dopant atoms inside the target and from tracer layers situated at both front and rear side of the target it has been possible to investigate the fast electron propagation. The results show that Cu K(alpha) yield emitted by the target rear side foil decreases with increasing compression, independently of rho(0). An electron collimation can also be observed for certain experimental conditions where a convergent resistivity gradient interacts with the fast electron beam. The second experiment was performed in a planar geometry with a compressing shock counter-propagative to the fast electron beam. In this case the areal density rho z seen by the electrons is constant during the compression in such a way that changes in the fast electron range should be ascribed to collective mechanisms. The study of the K(alpha) fluorescence, from buried fluorescent layers of different atomic numbers, shows that the electrons with energy

Abstract

Fast ignition requires a precise knowledge of fast electron propagation in a dense hydrogen plasma. In this context, a dedicated HiPER (High Power laser Energy Research) experiment was performed on the VULCAN laser facility where the propagation of relativistic electron beams through cylindrically compressed plastic targets was studied. In this paper, we characterize the plasma parameters such as temperature and density during the compression of cylindrical polyimide shells filled with CH foams at three different initial densities. X-ray and proton radiography were used to measure the cylinder radius at different stages of the compression. By comparing both diagnostics results with 2D hydrodynamic simulations, we could infer densities from 2 to 11 g/cm(3) and temperatures from 30 to 120 eV at maximum compression at the center of targets. According to the initial foam density, kinetic, coupled (sometimes degenerated) plasmas were obtained. The temporal and spatial evolution of the resulting areal densities and electrical conductivities allow for testing electron transport in a wide range of configurations.
