Coupling device between the first dynode of a photomultiplier and a sheet multiplier

摘要

photomultiplier tube (10) with a photou00adcathode (20), a first cylinder (30), a dynode electron multiplier device (40) along the lines of "leaves", and a coupling device (50) of the first device (30) dynode multiplier (40).according to the invention, the device (50) is formed of a first electrode (51) is composed of a side frame (52) cyu00adlindrique axis parallel to that of the upper frame and a multiplier device (53) through an opening (54) of passag e of the photoelectrons (21) to the first dynode (30), and, on the other hand.a second electrode (55) is located between the outlet (32) of the first (30) and the dynode input device (42) of the multiplier (40).
