A channel electron multiplier phototube having a channel electron multiplier, a transparent faceplate, and an anode assembly. The channel electron multiplier includes an insulating body having a curved passageway extending therethrough. A photoemissive element, and a secondary emissive dynode material is on the walls of the passageway. The passageway, together with a photoemission film of the photocathode assembly and the anode of the anode assembly define an evacuated closed region. Preferably, the electron multiplier is a monolithic ceramic body.
