Abstract

La présente addition concerne un tube d'émission d'ondes électromagnétiques. La trajectoire du faisceau 1 est une trajectoire fermée, sur laquelle les électrons sont guidés par un champ magnétique de direction fixe fourni par les bobines 3. Le faisceau repasse indéfiniment dans les accélérateurs 7 et les collecteurs 5, pendant tout le temps où il reste sur sa trajectoire. Ce temps est prolongé au maximum en prévoyant, en certains points, des bobines 9 de focalisation des électrons sur leur trajectoire Mêmes applications que celles de la demande principale, fusion thermonucléaire notamment.
