Abstract: A time-space-resolved 1-D X-ray imaging system is developed to investigate the X-ray power distribution with one-dimensional space and continuous time resolution in Z-pinch experiments performed on Angara-5-1 facility. A slit relays the 1-D image of the pinch to a scintillator which converts X-ray to visible light, and the image is subsequently relayed to the cathode of an optical streak camera via an optical fiber array, optical fiber bundles and a lens and finally the time resolved 1-D X-ray distribution is obtained. As the inner plasma reduced the R-T instability of the implosion, the (40+20) double tungsten array implosion had a better axial implosion uniformity and synchronization than the 40 single tungsten array implosion, as well as the higher peak radiated X-ray power. Axial implo
