ABSTRACT:
Photomultiplier tube 10 segmented into a plurality of elementary photomultipliers 11 comprising a photocathode 12 and a multiplier 13 of the type using sheets partitioned into a plurality of elementary multipliers 14. According to the invention the input space of the tube 10 located between the photocathode 12 and the multiplier 13 is partitioned into elementary input spaces 15 associated with the elementary photomultipliers and defining a plurality of elementary photocathodes 16, with each elementary input space 15 having a focussing electrode which causes the photo-electrons emitted by the associated elementary photocathode 16 to converge on the corresponding elementary multiplier 14.
