Abstract:
A system for detecting electromagnetic radiation or an ion flow, including an input device for receiving the electronic radiation or the ion flow and emitting primary electrons in response, a multiplier of electrons in transmission, for receiving the primary electrons and emitting secondary electrons in response, and an output device for receiving the secondary electrons and emitting an output signal in response. The electron multiplier includes at least one nanocrystalline diamond layer doped with boron in a concentration of higher than 5·1019 cm−3.

Abstract:
An image intensifier tube and a night vision system fitted with such a tube. The tube body of the image intensifier tube includes a multilayer ceramic substrate fixed in a sealed manner to an input device and to an output device so as to assure leaktightness of a vacuum chamber delimited by the tube body. The multilayer substrate also maintains a microchannel plate arranged between a photocathode and a phosphorus screen, and supplies voltage to the photocathode, the plate, and the phosphorus screen.
