Focalisation forte.(...) si l'on construit un champ dans lequel n prend alternativement des valeurs positives et négatives assez grandes, permettant ainsi à la particule qui y parcourt une orbite circulaire de rayon r d’y rencontrer successivement des secteurs dans lesquels le champ magnétique la focalise dans un plan horizontal, et la défocalise verticalement, et des secteurs où c'est l'inverse qui se produit, il peut en résulter une action nettement focalisatrice tant radialement que le long des lignes du champ. Cette focalisation est connue sous le nom de "focalisation à gradient alterné"(A. G.). 3, record 1, French, - focalisation%20par%20alternance%20de%20gradients
