Abstract[English]
A method of manufacturing a jointless superconducting multi-coil (1, 1') comprises the steps of providing a superconducting element (2) and winding a first part (2b1) around at least part of a first mandrel (3) so as to form a first pre-coil (4) of a first coil (5), winding at least part around at least part of the first mandrel (3) so as to form the first coil (5), and i) winding a second part (2b2) around at least part of a second mandrel (6) so as to form a second pre-coil (7) of a second coil (8) and winding at least part around at least part of the second mandrel (6) so as to form the second coil (8), or ii) winding a second part (2b2) around at least part of the first mandrel (3) so as to form a second pre-coil (7') of a second coil (8') and winding at least part around at least part of the first mandrel (3) so as to form the second coil (8'). The multi-coil (1, 1') comprises the first coil (5) and the second coil (8, 8') being arranged above one another with respect to a longitudinal direction (Lc, Lc') of the multi-coil (1, 1').[French]
Un procédé de fabrication d'une multi-bobine supraconductrice sans jonction (1, 1') comprend les étapes consistant à fournir un élément supraconducteur (2) et à enrouler une première partie (2b1) autour d'au moins une partie d'un premier mandrin (3) de manière à former une première pré-bobine (4) d'une première bobine (5), à enrouler au moins une partie autour d'au moins une partie du premier mandrin (3) de manière à former la première bobine (5), et i) à enrouler une seconde partie (2b2) autour d'au moins une partie d'un second mandrin (6) de manière à former une seconde pré-bobine (7) d'une seconde bobine (8) et à enrouler au moins une partie autour d'au moins une partie du second mandrin (6) de manière à former la seconde bobine (8), ou ii) à enrouler une seconde partie (2b2) autour d'au moins une partie du premier mandrin (3) de manière à former une seconde pré-bobine (7') d'une seconde bobine (8') et à enrouler au moins une partie autour d'au moins une partie du premier mandrin (3) de manière à former la seconde bobine (8'). La multi-bobine (1, 1') comprend la première bobine (5) et la seconde bobine (8, 8'), lesquelles sont disposées l'une au-dessus de l'autre par rapport à une direction longitudinale (Lc, Lc') de la multi-bobine (1, 1').
