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.%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.
