摘要：

It is important to characterize the dynamic hohlraum's radiation and coupling efficiency in Z-pinch physical experiments. The difficulty in the columned dynamic hohlraums presents unique challenges and opportunities for target fabrication, especially their self-adaptivity. Columned dynamic hohlraums were developed. The low-density CHO foams were assembled and fixed by assistant clamp and their self-sustaining ability. In the condition of small strain, wire-arrays and foams can automatically adapt to the environment change of target chamber, through free rotation and slide in micron-level. The results show that, the dynamic hohlraums meet the requirement of the Z-pinch physics experiment, and is self-adaptive on the Angara-5-1 facility. The maximal X-ray temperature is 62.7 eV, and the result reproducibility is more than 91.5%.
