通道型二次电子倍增器分为玻璃二次电子倍增器和陶瓷二次电子倍增器两个大类,其形式有直管式、弧形、波形、平面螺旋和立体螺旋五种.玻璃二次电子倍增器是用特种高铅玻璃拉成毛细管,在高温(350—400℃)氢气氛中还原,玻璃表面生成一层厚为I00A的N型铅半导体膜所制成的.在国外,这种倍增器于60年代初期出现.有不少文献 Channel-type secondary electron multiplier is divided into glass secondary electron multiplier and ceramic secondary electron multiplier two broad categories, its form has straight tube, arc, waveform, plane spiral and three-dimensional spiral five glass twice The electron multiplier is made of special high-lead glass capillaries, reduced in a hydrogen atmosphere at high temperature (350-400 ℃), the surface of the glass to produce a layer of N-type lead semiconductor film thickness of I00A made in abroad, this The multiplier appeared in the early 1960s. There is a lot of literature
