Abstract
L'invention concerne un enroulement en solénoïde supraconducteur avec une compensation des gradients axiaux. L'enroulement avec compensation des gradients axiaux des ordres 1 à 7 est réalisé en fil supraconducteur de section rectangulaire. Il comporte une partie principale en plusieurs couches ainsi que des parties auxiliaires et supplémentaires à chaque extrémité de la partie principale. Une autre partie d'enroulement est disposée au centre de la partie principale, et toutes les parties d'enroulement sont connectées en série pour être parcourues par le même courant. L'invention s'applique notamment à un spectromètre à résonance magnétique nucléaire.
