ABSTRACT:
Making glass microchannel plates by drawing bundles of large numbers of glass tubes sufficiently to reduce the cross-sectional sizes of openings through the tubes to desired microchannel size with minimal distortion of original tube shape and wall thickness in resulting assemblies. Drawing is accomplished with no less than two separate steps; a first step being effected with large pulling force and minimal heating and a second step effected with relatively small pulling force, heating to relatively high viscosity and rapid drawing for short exposure to heat.
