The CT technique applied to ICF has been developed and a three dimensional (3D) image reconstruction program(CT3D) was performed.The program CT3D is used to numerically study the 3D reconstructed images of target's plasma by using a multiplicative algebraic reconstruction technique (MART) from five pinhole camera images obatined along different sight directions on ‘Xingguang Ⅱ’ device,so that 3D images of ICF's tagets are obtained.The simulated results show that the CT technique can be applied to ICF experiments.

An numerical method was developed for measuring radiant temperature using a set of absorption-foils coupled to soft x ray streak camera, SXRSC, in laser plasma experiments. An numerical code, SCC, was given. An x-ray intensity ratio vs temperature was calculated for Parylene, C₃H₆, Formvar, Mylar and Aluminum. A suitable range of the measuring temperature was discussed to some absorber.
