等离子体喷射X光时空分辨测量
-
摘要: 在“神光”强激光装置上对0.53 μm 激光产生的等离子体喷射进行了X光时空分辩诊断。首次利用多针孔阵列成像技术结合软X光扫描相机观察激光加热区和X光加热区等离子体的运动,获得了初级和次级等离子体膨胀速度等结果。Abstract: Diagnostic of green laser–produced plasma evolution was conducted on Shenguang laser facility. By utilizing a multipinhole array coupled to a soft X – ray streak camera, the plasma evolution in laser heated area (primary plasmas) and X –ray heated area (secondary plasmas) was observed. Expansion velocities of primary plasmas and secondary were obtained, discussion was also made.
