    Abstract: A fibre optic photocathode is provided that is useful in achieving the strict dimensional constraints of instrumentation and array use, in which the output (6) of a high intensity light source, such as a laser, is transmitted in the core (2) of a clad optical fibre (1) to the cathode location, where a conducting cathode material (4), having a work function cor­responding to the frequency of the light source in which the photon energy of the light (6), being slightly above the work function of the material (4), is positioned essentially in contact with the core (2) of the optical fibre (1). The photocathode (4) may be coated directly on the optical fibre (1). The end of the fibre core (2) may further be shaped to increase the extraction field so as to provide an intense optical emission spot. The optical fibre cladding may provide precision advantage in shaping. Electrical connection to the cathode material (4) may be facilitated by connection to a metal coating over the optical fibre cladding (3) or extending the cathode material (4) to an adjacent support.

    Abstract: Le procédé consiste à déposer sur un substrat (2), éventuellement poli, une première couche (44) d'Au ou Pt sous une épaisseur d'environ 200 nm ou plus par pulvérisation cathodique, puis une seconde couche (16) de MgO sous une épaisseur de 2 à 10 nm également par pulvérisation cathodi­que, le substrat étant constamment maintenu sous atmosphère contrô­lée pendant les deux dépôts, ainsi qu'entre ceux-ci.

    Abstract: A photoelectron mask for photo cathode image projection includes a transparent substrate (11), a pattern (12) formed on a main surface of the transparent substrate. The pattern includes a non-transparent material. The mask also includes a photoelectron emission film (13) formed so as to cover the main surface of the transparent substrate on which the pattern are formed. The photoelectron emission film includes a material selected from the group consisting of pure platinum, a platinum-rich material containing platinum as the major component, and a platinum compound.
