Segmented photomultiplier tube with high collection efficiency and reduced cross-talk.

摘要

Photomultiplier tube (10) is segmented into a plurality of elementary photomultipliers (11), comprising a photocathode (12), a plurality of elementary electron multiplier (13) of the "apertured sheet" type, and a plurality of electrodes (14) of carrying out the convergence of the photoelectrons emitted by the photocathode (12) on the said elementary multipliers (13). According to the invention, the homologous sheets (15) of the elementary multipliers are carried out on a same conductive plate (16) segmented having a dead zone (17) between the active areas (18) with holes corresponding to different multipliers (13), while the said focusing electrodes (14) are made from a same conducting sheet (19) is pierced with holes (20) of the photoelectrons towards the elementary multipliers (13). br / application to the physics of high energies.
