Title
(EN) MAGNETRON CONDITION MONITORING
(FR) SURVEILLANCE DE L'ÉTAT D'UN MAGNÉTRON
Abstract
(EN)
Disclosed herein is a high-power device for supplying a radiofrequency electromagnetic field to a waveguide. The device comprises a magnetron configured to supply a radiofrequency electromagnetic field to a waveguide and a control unit configured to control the magnetron to output radiofrequency energy to the waveguide. The magnetron comprises a high voltage pulse connection enclosed in an enclosure, a heater connection configured to allow an electrical connection to penetrate the enclosure and a mechanism configured to transmit data between the magnetron and the control unit.
(FR)
L'invention concerne un dispositif haute puissance destiné à fournir un champ électromagnétique radiofréquence à un guide d'ondes. Le dispositif comprend un magnétron conçu pour fournir un champ électromagnétique radiofréquence à un guide d'ondes et une unité de commande conçue pour commander le magnétron pour délivrer de l'énergie radiofréquence au guide d'ondes. Le magnétron comprend une connexion d'impulsions haute tension enfermée dans une enceinte, une connexion de chauffage conçue pour permettre à une connexion électrique de pénétrer dans l'enceinte et un mécanisme conçu pour transmettre des données entre le magnétron et l'unité de commande.
