摘要

P the invention relates to the chains of display operating in pulse, to convert the photons -. & / p & & p & instead of the photoelectron multipliers used to observe the cathodoluminescent screen whose terminal of the stages of the chains of the prior art, the invention provides for the conversion of the fast electrons to the last stage in the slow electrons, a target with a secondary emission, placed approximately at the location of this screen in these chains, associated with two gates extracting and braking assembly (7), ensuring a multiplication slow electrons / fast electrons high. Four plates 13 and collect the secondary electrons. The same applications as the chains of the prior art, a scan in particular. / p
