Study on movement of gold bubble plasma in hohlraum
-
摘要: 在神光Ⅲ主机装置,利用16束激光注入黑腔产生二维柱对称、接近点火状态的等离子体环境。利用一台X光分幅相机首次获得金泡等离子体的运动演化过程和不同时刻金、充气等离子体边界的绝对位置。通过精密实验与二维辐射流体程序模拟结果比较,验证了改进模型的合理性和可靠性。Abstract: Recent experiments on Shenguang Ⅲ laser facility have explored gas filled hohlraums to create plasma condition that is close to the ignition status. An X-ray framing camera was used to acquire the time-resolved movement images of the gold bubbles. The experimental results are simulated with a phenomenological model very well, demonstrating its validity and rationality.
