MAGNETRON

Une cathode d'un magnétron ayant une extension radiale destinée à contenir les bornes de la cathode 6, 7 est supportée par des bras de support de cathode 3, 4 beaucoup plus courts, étant donné que ces bras sont montés dans une paroi d'extrémité 18 de l'extension radiale qui est positionnée plus près de l'extrémité de cathode de l'extension radiale que de l'autre extrémité. Cela dévie les éventuelles vibrations vers une bande de fréquences plus élevé, qui risque moins d'être excitée dans l'éventualité où le magnétron serait déplacé rapidement, comme dans un système d'accélération linéaire utilisé pour la radiothérapie.
