A novel x-ray imaging method, providing spatial resolution of 10 μm, temporal resolution 10 ps, and spectral resolution of E/ΔE = 200 (E: photon energy), is suggested to diagnose laser driven fusion plasma. This scheme consists of a monochromatic x-ray imager with the use of two-dimensional (2D) curved crystals and an imagesampling streak camera. Feasibility of the method was studied using GEKKO XII laser and chlorinated plastic shell targets. Early appearance of Cl-Heα line emission during the implosion stage was found for the present conditions, which made image reconstruction difficult.
