Abstract

The invention relates to a multi-channel photomultiplier tube (1) comprising: a photon-transparent window (5) which is equipped with an inner face (7), and a light-emitting layer (2) which is disposed on the inner face (7) of the transparency window (5). The invention is characterised in that the transparency window (5) comprises an equal number of concavities (8) to the number of channels in the tube (1), said concavities (8) taking the form of parts (8) that are hollowed out from the inner face (7) of the transparency window (5), with each concavity corresponding to a channel. In this way, the transparency window (5) is equipped with hollow parts (8) and thick parts (23) corresponding to the non-hollow parts, the surfaces of said hollow parts (8) being covered with a light-emitting layer (2).
