ABSTRACT:
A photomultiplier tube comprises a photocathode (10) deposited on an input window (20) sealed to one end of a sleeve (30), an input electrode (40), and an electron multiplier (50) with stacked dynodes. The input electrode (40) is constituted by a truncated cone conductor on the inside of which the electron multiplier (50) with stacked dynodes is deposited. A generator (61,62) of a material forming the photocathode (10) is advantageously placed in the space (70) situated between the input electrode (40) and the sleeve (30).
