摘要
在星光和神光激光装置上,用空间-时间分辨、能量-时间分辨技术,激光探针光技术以及法拉第电荷收集器,研究了平面金靶、玻璃球靶、黑洞腔靶的激光等离子体膨胀过程以及离子发射速度分布。观察到了球靶的球体与支撑杆之间以及激光未照射区的等离子体喷流结构。获得了金柱腔靶在特定功率密度下的解体时间。
The expansion processes of laser - heated plasmas for both gold planar targets and glass sphere targets were studied using space -and time-resolved and energy -and time-resolved techniques and a laser probe on the Xing Guang (1011W)and Shen Guang (1012W)laser facilities. The blow -off stream structure was observed on the sphere target surface where a support pole was attached. The disintegration process of hohlraum targets was studied semi -quantitatively with the laser probe. Furthermore, the speed distributions of ions ejected from both planar and hohlraum targets were measured with Faraday cups.
