Abstract
Recent experiments at the HELEN laser at AWE have focused on investigations into the performance of a series of scaled NOVA halfraum targets. These were varied from scale 1 to scale 0.1, and used a single beam at 0.53 μm to irradiate the target. The aim of these experiments was to investigate performance limitations for higher temperature small hohlraums. Target diagnostics included time-resolved X-ray power measurements, full aperture measurements of stimulated Raman and Brillouin backscatter, and time-integrated soft and hard X-ray spectrographs. Analyses of the results from this campaign are presented with particular emphasis on the conditions present in the smallest scale targets, including comparison with calculated performance.
