Abstract

L'invention se rapporte à un électro-aimant supraconducteur pour accélérateur de particules porteuses de charge, qui comprend une enveloppe cylindrique sous vide (1), à l'intérieur de laquelle sont montés, dans une disposition coaxiale par rapport à son axe longitudinal (2), un récipient (3) contenant de l'hélium liquide (4), un enroulement supraconducteur (7) placé dans le récipient, une chambre sous vide (4), une barrière d'azote (8) et une isolation thermique (9). Dans le récipient (3) contenant l'hélium liquide (4) est disposé un contrôleur de radiation (16) utilisant l'hélium liquide (4) comme milieu d'enregistrement. L'élément sensible (17) du contrôleur de radiation (16) est connecté à des bornes électriques (24, 25) de l'enveloppe cylindrique sous vide (1).
