Electron multiplier plate with controlled multiplication, multiplier element comprising the said plate, multiplier device comprising the said element and application of the said device to a photomultiplier tube. Secondary emission electron multiplier plate (10) of the "aperture plate" type, comprising multiplier apertures (11), each having an input side (12), an output side (13), and an efficacious multiplier partition (14) having emissive power. Multiplier plate (10) has at least one elementary multiplier pattern (15) comprising a plurality of multiplier apertures, at least the said efficacious multiplier partitions (14a) of the peripheral multiplier apertures (11a) of the pattern (15) being oriented towards the interior of the said pattern.
