Three-dimensional separated flow represents a domain of fluid mechanics of great practical interest that is, as yet, beyond the reach of definitive theoretical analysis or numerical computation. At present, our understand­ ing of three-dimensional flow separation rests principally on observations drawn from experimental studies utilizing flow visualization(More)
An amplitude analysis of the reaction rtp * p(i~-n+i~') at 7 GeV/c is in progress. Although our method of analysis and assumptions are quite different from those of the Illinois group, our preliminary results are nevertheless consistent with theirs. We fit coherent amplitudes, not the density matrix, and make different assumptions about decay amplitudes of(More)
The fast ignition (FI) concept is a variant of inertial fusion in which the compression and ignition steps are separated. Calculations suggest this would allow a substantial improvement in target gain, and could form the basis of a very attractive power plant. Transporting the energy to ignite a target involves the physics of light-driven relativistic(More)
Isochoric heating by electrons has been measured in the two limiting cases of small area thin foils with dominant refluxing and cone-long-wire geometrywith negligible refluxing in thewire. Imaging ofCuK fluorescence, crystal x-ray spectroscopy of Cu K shell emission, and XUV imaging at 68eV and 256eV are discussed. Laser power on target was typically 0.5PW(More)
The characteristics of relativistic electrons generated in short-pulse laser plasma interactions are important for evaluating the success of the fast ignition concept. The important parameters include the spectrum, laser to electron conversion efficiency, and divergence angle of the electrons at the interface. Simulation results using 3-D particle-in-cell(More)
