The experimental investigation on the X-ray radiation transport is made.The method for studying X-ray transport is analyzed.Two kinds of targets which are source and cylinder targets are investigated separately.From the source target,the initial condition for transport is obtained.From transport target,the transport result is obtained.The experimental results for the two kinds of targets measured by a soft X-ray spectrometer,flat response X-ray diffraction and transmission gratings are given and analyzed using the simple X-ray radiation transport model.Plasma expansion in cylinder targets are investigated.
