The experimental result of the newly developed 30.4 nm extreme ultraviolet imaging detector was reported in detail, which adopted wedge strip and zigzag anode (WSA), V-stack high-gain microchannel plate (MCP) components, low-noise electronic readout system, and other advanced techniques. Simulated images were obtained successfully by using the single-photon counting imaging technique in the laboratory. The experimental setup system was established and the detector imaging linearity, resolution, the dark count rates etc are studied. The research shows that the detector has an effective area of 45 mm in diameter, spatial resolution better than 100 μm, and low dark count rates about 0.4 count/(cm2·s), with good image linearity and simple structure.
