Abstract :
Summary form only given. Analysis of time gated pin hole camera data has provided measurements of shock velocity in dynamic hohlraum experiments. A novel method for determining the center of the image using a least squares fit to multiple radii versus angle measurements of the shock front has been developed. Shock speeds of order 30 cm/mus have been measured. Additionally, the uniformity of the shock front can be determined with uncertainties of a few percent
