摘要
研制了针对Z-pinch强X射线辐射源的软X射线聚束透镜，利用西北核技术研究所“强光一号”加速器产生的钨丝阵高温等离子体辐射，对在高功率密度软X射线入射条件下的聚束透镜开展了实验。研究表明：由2401根X光导管组成的透镜，在输入软X射线功率密度达1.0×108 W/cm2时，透镜的平均传输效率为9.6%，在软X射线传输过程中等离子体溅射被导管内壁吸收，透镜后焦点处能获得洁净的软X射线源，平均功率密度达到1.15×109 W/cm2。
Abstract
We made soft X-ray lens and combined it with high-temperature plasma radiation which was produced on Qiang-Guang Ⅰ facility. The transmission characters of lens were measured. It is shown that, for the lens manufactured of 2401 X-ray capillaries, when the power density of the incident soft X-ray is 1.0×108 W/cm2, the average transmission efficiency of lens is 9.6%, and the power density 1.15×109 W/cm2 of soft X-ray source without plasma fragment can be obtained at focal point.
