Coupling device between a first dynode of a photomultiplier and a mehrblattverielfacher.

摘要

In a photomultiplier tube 10 comprising a photocathode 20, a first dynode 30 cylindrical and a multiplier device 40 of the electrons of the type "sheet", a device 50 of the coupling of the first multiplier dynode 30 to the device 40 is characterized in that the axis 41 of the voltage-multiplier device 40 is parallel to the axis 11 of the tube, said device 50 is formed, on the one hand, a first electrode 51 made up of a cylindrical lateral reinforcement 52 of the same axis 11 as the tube and an upper frame 53 pierced with an opening 54 of the photoelectrons 21 towards the first dynode 30, and, on the other hand, of a second electrode 55 plane situated between the output 32 of the first dynode 30 and the input 42 of the voltage-multiplier device 40. / p & & p & application of the photomultiplier tubes.
