Abstract: The plasma closure images of two-dimensional space and one-dimensional time for 1.053m m slanting incidence laser were observed successfully for the first time at the“XingguangII”facility with an X-ray twelve-frame camera. The plasma closure velocities under the condition of laser slanting incidence have been obtained separately by experiment and one-dimensional model. The experimental results show that under the same conditions the plasma expanding speed is 15% higher for half-cavity targets than that for hole targets.
