    摘要: Process for the production of an electrical insulant (5) placed in an intense electrical field, particularly between two electrodes (1, 2) of an electron tube. The insulant (5) is a crystalline material, whose free surfaces (7) in vacuo (6) have been treated so as to reduce or eliminate crystallization defects. The treatment is checked by measurements of a particular optical or mechanical property of the free surfaces. The breakdown voltage can be multiplied by three or four compared with conventional insulants and can approach the breakdown voltage of the vacuum.

    摘要: A protective device for a neutron tube including an ion source having an anode (2) which is brought to a positive potential relative to a cathode (3) by means of a source supply. An ion beam accelerated by means of an acceleration electrode (5) strikes a target (6) disposed on an insulating support (9) and brought to a negative potential supplied by an HT supply. The protective device includes electric elements (11, 12) limiting the tube current and/or the target voltage, which are made unalterable by enclosing them inside the neutron tube, so that any attempt to modify the electrical parameters determining the normal operating conditions of the tube necessitates the opening of the tube.
