摘要: 在聚龙一号脉冲功率装置上首次完成了对带正弦扰动铝套筒Z箍缩的X射线背光照相实验。实验采用千焦耳激光器（1053 nm, 1 kJ, 1 ns）驱动固体靶材产生X射线, 然后利用基于球面晶体的单色背光照相技术以及直接点投影背光照相技术, 成功观测到约7.5 MA电流驱动条件下, Z箍缩铝套筒的外边界不稳定性发展情况。该实验验证了在聚龙一号装置上联合千焦耳激光器开展X射线背光照相实验的能力, 为后续精密Z箍缩物理研究奠定了基础。Abstract: The first X-ray backlighting of Z-pinched aluminium liner with sinusoidal perturbations experiment was carried out on PTS facility. A kilo-joule laser (1053 nm, 1 kJ, 1 ns) was used to drive the solid target to produce X-rays and the development of the instability of the Z-pinched aluminium liner outer edge, under a driver current of 7.5 MA, was successfully observed by using the monochromatic X-ray backlighting based on spherical-bent crystal and the direct point shadow radiography, respectively. This experiment confirmed the capability of X-ray backlighting on the PTS facility by union of the kilo-joule laser and it provided the foundation for the subsequent researching of the fine Z-pinch physics.
