Schlieren Diagnostics of Fused Quartz Heated by Intense Ion Beams

The thermodynamic response of matter heated with intense ion beams was analyzed using the schlieren technique. The energy deposition zone and the propagation of the thermal wave were visualized in the experiment. Fused quartz has been chosen as a target to investigate the phenomena in a material with high yield point. The temperature in the ion beam heated region was estimated using the schlieren data and by analysis of the material changes after irradiation.
