    Abstract: An ionising radiation detector comprising a chamber (1) filled with a noble gas and provided with an internal proportional counter (2) defining, between itself and an upper wall of the chamber, an absorption region (A) in which the radiation is ionised. The proportional counter comprises at least one anode (6) and at least one cathode (5) that are parallel to one another and separated by a layer of insulating material (7). Both the cathode and the layer of insulating material include at least one through-hole (8) in which a substantially uniform electric field is provided to form a region where electrons produced by the ionisation of the radiation are multiplied. Said detector is useful in medical imaging, biology, crystallography and particle physics.

    Abstract: L'invention concerne un détecteur gazeux de rayons X pour l'analyse de la matière par étude de la diffraction des rayons X.
    Pour minimiser les erreurs de parallaxe sans utiliser d'électrodes auxiliaires sphériques difficiles à fabriquer, on propose d'engendrer un champ radial dans tout l'espace gazeux (40) uniquement à l'aide d'électrodes d'entrée (36) portées à des po­tentiels appropriés et à l'aide d'électrodes latérales (44) égale­ment portées individuellement à des potentiels appropriés. Par modification des potentiels on peut déplacer le centre des équipo­tentielles sphériques pour permettre l'analyse sans erreur de pa­rallaxe d'échantillons (20) placés à des distances (D) variables de la fenêtre d'entrée (32) du détecteur.

    Abstract: A radiographic imaging device includes a gas avalanche detector detecting and locating X-ray or gamma ray ionizing radiation. The detector has a gas enclosure with an admission window for admitting incident X-ray photons; an intermediate plane electrode in the enclosure between and parallel to two end plane electrodes thereby forming an amplification space constituting a conversion space where the photons are convertible into electrical charges made up of primary electrons and corresponding ions; the intermediate electrode being operable at an electrical potential relative to the electrical potentials of the end electrodes suitable for generating an electric field causing multiplication of the electrons by the avalanche phenomenon in the amplification space near the intermediate electrode; one of the end electrodes being a collector electrode for picking up the electrical signals induced by the ions; and said window being level with the amplification space and between the intermediate plane and collector electrodes.
