摘　　要：A series of liner-like Z-pinch loads with a novel configuration have been investigated experimentally for the first time on Qiangguang-I facility in China.The metallic layer is sputtered on the inner surface of the cylindrical SiO 2 substrate tube.In the preliminary experiment,the electric current flowed through the metallic load during the prepulse.However,the currents also flowed through the outer surface of the SiO 2 substrate during the main pulse.After the dielectric length had been increased in the formal experiment,most of the current flowed through the metallic load until radial radiation peak was measured by radiation monitor.As the line mass of the metallic load increases,the peak time of radial radiation also increases.Axial ultravi-olet frames indicate that the radiations are nearly azi-muthally uniform at first,but the uniformity becomes worse after radial radiation peak.The clearly separated boundary between the metal plasmas and the substrate has not been observed in the experiment.Experimental results are discussed and compared with simulation using the one-dimension radiation hydrodynamics code MULTI-IFE.
