Sheet-type dynode, electron multiplier and photomultiplier having such dynodes

摘要

(d) dynode electron multiplier consisting of two half dynodes (d, du2032) brought to a parallel electrical potential (v), which is in the form of components (10,20) leaves holes (11,21).according to the invention, the second half dynode (du2032), known as the half dynode emitter is reu00adcouverte material (25) of a secondary emission, the electron systems (30) occurring on the surface (23) of the metal sheet (20) and that the corresponding d emi dynode transceiver (du2032) and the first half dynode (d), the so-called half dynode mining.come between them.;application of photomultiplier tubes.
