Abstract: An image intensifier or other tube including a photocathode or the like and a channel-type electron multiplier therefor. The multiplier includes a perforated glass plate with a conductive electrode layer evaporated on each of two opposite sides thereof. Each of the electrodes has a plurality of holes therethrough that lie in registration with the plate holes. A layer of titanium is evaporated onto the output electrode. A substantial increase in photocathode life is then achieved. Alternatively, the said three layers need not be employed. Instead, the output electrode itself may be made of titanium. In this case, no other layer need be evaporated over the output electrode.
