A microchannel plate gated X-ray framing camera(XFC) was used to take pictures of Au plasma radial convergence in hohlraums on Shenguang-Ⅱ laser facility. According to XFC image manipulation by MATLAB and measurement of radiation temperature, hohlraum closure of Au plasma generally will not occur in hohlraums with sizes of 1 000 μm×1 800 μm and 1 200 μm×2 100 μm,on condition that there is no gas and low-Z filling in hohlraum, by laser beams with 351 nm wavelength, 2.4 ns pulse duration and 8×300 J energy on Shenguang-Ⅱ laser facility. While obvious hohlraum closure of Au plasma would occur in the standard hohlraum(800 μm×1 350 μm ) with the laser applied for about 1.5 ns. Additionally, XFC image manipulation unveiled Au plasma radial convergence speed in the three hohlraums, w
