Abstract: The cathode for photo-electron emission 5 is comprised of an alkali metal containing layer 5d made of material for emitting photo-electrons by the entry of light or for emitting secondary electrons by the entry of electrons, such as particles which consist of an alkali antimony compound, on an Ni electrode substrate 5c on which an Al layer 5b is deposited, and has an intermediate layer 5a made of carbon nano-tubes between the alkali metal containing layer 5d and the Ni electrode substrate 5c, therefore the defect density inside the particles is decreased, and the recombining probability of electrons and holes drops remarkably, which improves the quantum efficiency.

Abstract: A photomultiplier includes a photocathode and an electron multiplier. A typical structure of the electron multiplier is obtained such that a dynode unit constituted by stacking a plurality of dynode plates in the incident direction of photoelectrons, an anode plate, and an inverting dynode plate are stacked. The anode plate (5) has electron through holes at a predetermined portion to cause secondary electrons emitted from the dynode unit (13) to pass therethrough. Each electron through hole has a diameter on the inverting dynode plate side larger than that on the dynode unit side, thereby increasing the capture area of the secondary electrons orbit-inverted by the inverting dynode plate.

Abstract: There is disclosed a process for forming a photocathode having high quantum yield which comprises the first step of making a number of fine concavities and convexities (14) in a surface (11) of a substrate (12) finished substantially in a mirror; the second step of blunting the fine concavities and convexities (14); and the third step of coating a photoelectron emissive material (15) on the surface of the substrate (12).

Abstract: L'invention concerne un procédé de fabrication d'un inten­sificateur d'images radiologiques.
Avant de l'introduire dans l'intensificateur, on recouvre la grille (G₃) qui est la plus proche de l'anode (A) d'une couche d'un matériau, conducteur de l'électricité, et ayant la propriété d'oxyder les métaux alcalins. On supprime ainsi l'éclairage parasite de l'écran dobservation (4) dû aux métaux alcalins déposés involontairement sur cette grille (G₃) lors de l'élaboration de la photocathode (3).

Abstract: The present invention improves sensitivity of the ultraviolet band of a photoelectric surface. A photoelectric surface 1 includes a window material 2 that transmits ultraviolet rays, a conductive film 3 that is formed on the window material 2 and has conductivity, an intermediate film 4 that is formed on the conductive film 3 and is formed of MgF 2 , and a photoelectric conversion film 6 that is formed on the intermediate film 4 and is formed of CsTe. Since the photoelectric surface 1 includes the intermediate film 4 formed of MgF 2 , the sensitivity of the ultraviolet band is improved.
