The suppression of the Rayleigh-Taylor instability that occurs due to self-Radiation in a multiablation target was investigated. It was demonstrated that in a high-Z doped plastic target, two ablation surfaces were formed separately, one driven by thermal radiation and the other driven by electron conduction. It was found that the growth of the Rayleigh-Taylor instability was significantly suppressed on the radiation-driven ablation surface inside the target becasue of a large ablation velocity and long density scale length. Using a brominated plastic target, a significant reduction in growth rate was observed.
