Abstract

Ce dispositif assure le contrôle des différents paramètres (fréquence F, courant I, champ magnétique H) de fonctionnement d'un magnétron qui peut délivrer des signaux H.F. de sortie de différentes puissances par variation de la puissance qui lui est appliquée, le fonctionnement du magnétron restant optimum pour la fréquence et la puissance de sortie sélectionnées. Ce dispositif comporte un système d'asservissement, imposant, pour une puissance P, de sortie sélectionnée, et une fréquence F sélectionnée, le courant I de fonctionnement du magnétron et le champ magnétique H correspondant. Un système d'accord de fréquence du magnétron peut être commandé par le système d'asservissement. Application : alimentation H.F. d'un accélérateur de particules à énergie réglable.
