ABSTRACT:
An electron multiplier of the perforated sheet type includes two successive sheets constituting a dynode which has several multiplier channels in common. For controlling the gain of a given channel (A), a control electrode (30) is provided in the form of a sheet inserted between the sheets (14, 15) of a dynode (Dn) which has a grating window (33) controlling the gain of the channel (A) in question, and one (or several) aperture(s) (34) in accordance with the number of remaining channels. Another channel (B) is controlled by another electrode (31) inserted between the sheets (16, 17) of another dynode (D.sub.n+1). Also disclosed is a multi-channel photomultiplier tube which includes such an electron multiplier.
