Authors:

AJ Cole, MH Key, A Ridgeley, DA Brown, PA Norreys, ER Wooding, TW Barbee

Abstract:

An instrumental technique for recording monochromatic X-ray images of laser-produced plasmas has been developed using a Layered Synthetic Microstructure in combination with a pinhole camera. Well resolved images in 6 Å X-ray emission from 10 μm gold microdots are demonstrated. © 1987.

Abstract:

The authors present a detailed investigation of ablatively driven gas-filled polymer shell targets irradiated by the 351-nm 2-kJ 4-TW Omega 24-beam laser system. The implosion of these targets was diagnosed with an extensive array of plasma, X-ray, and nuclear diagnostics. Detailed characterization of the multibeam laser output provided an estimate of the illumination nonuniformities imposed on target. Targets were fabricated from polystyrene or polyvinyl alcohol shells of 200-400- mu m diameter and 5-10- mu m wall thicknesses. Additional polymer layers and ultrathin metallic layers were added to reduce the initial aspect ratio and provide shine-through inhibition and weak X-ray signatures of ablation front penetration, respectively. A detailed comparison of the symmetry and performance of these target implosions has been made with the predictions of the one-dimensional (1-D) and 2-D hydrodynamic codes LILAC and ORCHID, respectively.
