  • Electronic tube with simplified collector
    Patent number: 6984940
    Abstract: The invention relates to amplifying electron tubes operating at microwave frequencies. The electron tube comprises: a pump-out tube that allows the vacuum inside the electron tube to be created; an electron gun that emits an electron beam inside the electron tube; a collector that directly collects a first portion of the electron beam. The pump-out tube directly repels a second portion of the electron beam in the direction of the collector.
    Type: Grant

  • Cooling an electronic tube
    Patent number: 6858973
    Abstract: The invention concerns the electronic amplifier tubes operating at radio-frequency. The electronic tube includes a long tubular sleeve containing an electron beam, a housing supporting the sleeve mechanically, and means to provide heat transfer from the sleeve to the housing to cool the sleeve. The means to provide the heat transfer include a resin filling a free volume located between the sleeve and the housing.
