In the hohlraum of laser indirect-drive inertial confinement fusion (ICF), hydrodynamic moving processes of radiation-ablated high-Z plasma have great influence on laser injection efficiency, radiation uniformity and measurement of the hohlraum radiation temperature at the diagnosis hole (DH). To study the plasma filling in the DH, using laser-produced X-ray to heat low-Z foam-tamped high-Z gold DH, and using laser-irradiated Ti disk to generate 2-5 keV high and narrow energy X-ray as the intense backlighter source, the plasma movement in a hole was measured by an X-ray framing camera(XFC). A quantificational measuring method for the areal density distribution and evolution of plasma in a hole was studied.
