摘要:
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 (32) having a curved passageway extending therethrough. A photoemissive element (36a), 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 (42) of the anode assembly define an evacuated closed region. Preferably, the electron multiplier is a monolithic ceramic body (32).

摘要:
Phototube à multiplicateur d'électrons à canal comprenant un multiplicateur d'électrons à canal, une plaque frontale transparente et un ensemble anode. Le multiplicateur d'électorns à canal comprend un corps isolant (32) pourvu d'un passage incurvé qui le traverse. Un élément à émission photoélectrique (36a) et un matériau dynode émetteur secondaire se situent sur les parois du passage. Le passage définit, avec le film à émission photoélectrique de l'ensemble photocathode et l'anode (42) de l'ensemble anode, une zone fermée et sous vide. De préférence, le multiplicateur d'électrons se compose d'un corps céramique monolithique.
