摘要
采用玻璃多纤维拉制(GMD)技术研制并批量生产了微小通道(孔径4~5μm)还原铅硅酸盐玻璃微通道板(MCP),空间分辨率达到95lp/mm。优选皮-芯-实体边玻璃组合,解决了小通道实体边MCP制板过程中发生变形、破裂的难题;开发新的拉丝设备和技术以及细小直径单纤维的排棒、复式纤维的排屏工艺和相应的技术设备,保证单复丝拉制过程中纤维的尺寸误差不大于0.5%,解决了MCP增益的均匀性难题,实现了两步法拉丝制作孔径5μm以下MCP的工艺方法。制作的MCP平均孔径5μm,厚度为0.25mm,增益大于1×104(900V)。
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 1×10^4(900 V)on average.
