Excelitas C 1984 Channel Photomultiplier (CPM)
Multiplicateur d'électrons à canaux
Kanalelektronenvervielfacher (KEV)

A channel photomultiplier is built as a funnel of glass coated inside with a thin film of semi-conducting material, with negative high voltage applied at the wider input end, and positive voltage near ground applied at the narrower output end. Electrons emitted at any point are accelerated a modest distance down the funnel before impacting the surface, perhaps on the opposite side of the funnel. At the destination end a separate electrode (anode) collects the multiplied electrons. Compared to the photomultipliers with discrete dynodes, it is simpler to feed and more compact.
