Mass-modulated plastic microballoons have been ablatively imploded by green (0.53 μm) laser light at an absorbed irradiance of 2×1013 W cm-2. Temporally growing spikes are seen on the outside surface of the target; evidence of the occurrence of mass redistribution indicates that the spikes are due to the Rayleigh–Taylor instability. A growth rate of 0.52±0.06 of classical has been inferred.

    Collective beam dynamics will play a major role in determining losses in high intensity rings. We demonstrate here, using both analytic and computational models, that beam halo can form under the influence of transverse impedances, even for stable cases well below the instability threshold.
