ABSTRACT:
An electron mulitplexer dynode (D) comprising two parallel disposed half-dynodes (d, d') to which an equal potential (V) is applied, and which are in the form of metal sheets (10, 20) in which apertures (11, 21) are formed. According to the invention, the second half-dynode (d'), called emitting half-dynode, has an electron surface (23), and the said emitting half-dynode (d') and the first half-dynode (d), called extracting half-dynode, are arranged so as to be staggered relative to each other.
