Method of making a plate having a pattern of microchannels

摘要

An unetched microchannel plate is coated on one side with an etchant-resistant mask having a pattern of open areas. The core fibers in the open areas are then etched out to form a pattern of microchannels. The microchannels and the mask are metallized, after which the mask and its metal are stripped. When the other side of the plate is metallized in the usual manner, a microchannel intensifier plate with a pattern of microchannels results.
