在“星光Ⅱ”上首次利用Ｘ光１２分幅相机（ＸＦＣ）成功地观测到了１．０５３μｍ激光以４５°方向斜入射孔靶和半腔靶等离子体堵口的时间和二维空间图像，获得了等离子体堵口速度，同时通过一维模型给出了斜入射条件下的等离子体堵口速度。实验结果表明：相同参数条件下半腔靶与孔靶相比，等离子体喷射速度高约１５％。一维模型给出的等离子体喷射速度与ＸＦＣ测出的等离子体喷射速度在实验误差范围内是一致的。
For the first time, the X-ray 12-segment camera (XFC) was successfully used to observe the time and two-dimensional image of 1.053μm laser beam obliquely entering the perforation target and the half-cavity target plasma in 45 ° direction. The plasma plugging velocity was also obtained. The plasma plugging velocity under oblique incident conditions was given by a one-dimensional model. The experimental results show that the plasma jet velocity is about 15% higher than that of the target under the same parameters. The plasma jet velocity given by the one-dimensional model is consistent with the plasma jet velocity measured by XFC over the experimental error range.
