Claim 15:
16. A method of making a microchannel plate, comprising:
forming glass cores surrounded by respective glass cladding at a first angle relative to opposing input and output faces of a plate;
etching the glass cores to remove the cores entirely from the remaining glass cladding leaving a plurality of spaced channels;
forming a contact metal layer on both opposing input and output faces of the plate and partially into each of the spaced channels;
forming an electron backscatter layer on the contact metal on the input face and contiguously only partially into each of the spaced channel near only the input face;
forming a secondary electron booster layer on the electron backscatter layer on the input face and contiguously only partially into each of the spaced channels near only the input face; and
coupling the contact metal to a bias voltage to draw first strike electrons from the secondary electron booster layer, a portion of which are produced from primary electrons backscattering from the electron backscatter layer.
