Abstract
Conformément au brevet principal, ce dispositif comprend un seul électro-aimant de polarisation et de mesure pour produire le champ de polarisation et le champ de résonance ou champ de mesure. Le perfectionnement consiste en ce que l'aimant unique prévu pour produire le champ de polarisation 4 et le champ de résonance ou de mesure 5 est un électro-aimant à enroulements supraconducteurs 12, 13 ou cryo-aimant, comprenant un seul ou deux cryostats 9, 10 disposés en forme de demi-coquilles autour du tube de circulation 1.
