Title (EN) PRODUCTION OF A MICROWAVE DEVICE BY APPLYING A COATING OF YTTRIUM-IRON-GARNET TO THE SURFACE OF THE DEVICE TO SUPPRESS SECONDARY ELECTRON EMISSION
(FR) TRAITEMENT DE SURFACE ET PROCEDE PERMETTANT D'APPLIQUER LE TRAITEMENT DE SURFACE POUR SUPPRIMER L'EMISSION D'ELECTRONS SECONDAIRES
Abstract:
(EN) A microwave device with a secondary yield coefficient of less than 1 is produced by applying a coating of yttrium-iron-garnet to the inner surface of the device by sputtering.
(FR) La présente invention concerne un traitement de surface et un procédé permettant d'appliquer le traitement de surface à des éléments électriques, le traitement de surface comprenant un revêtement de grenat yttrium-fer (yttrium-iron-garn et / YIG) qui est appliqué sur la surface interne de l'élément par pulvérisation cathodique.
