The reducing lead silicate glass microchannel plate (MCP) with 4-5 μm channel is produced by the glass multifiber draw (GMD) technology,and its resolution is 95 lp/mm. The crack and twist of MCP during production can be avoided by optimizing the glass group of the skin,core and solid border. The dimensional error of fiber is within 0.5% during fiber-drawing by developing new fiber-drawing machines and techniques,arranging slender-diameter mono-fiber and multi-fiber stick. By these ways,the problem of gaining uniformity of MCP is solved. MCPs with less than 5 μm channels were made by the method of two-step stick-drawing. The channel diameter of MCP is 5 μm,thickness is 0.25mm,and gain is 1×10⁴ (900 V) on average.
