ABSTRACT:
A vacuum housing is provided for an electron tube having an anode and a cathode, the vacuum housing having a region containing a volume for the acceptance of the anode that is connected to a chamber for the acceptance of the cathode via a shaft-shaped housing section made of weldable material. A first part of the shaft-shaped housing section is integrally formed with a portion of housing which contains the volume for the acceptance of the anode. A second part of the shaft-shaped housing section is integrally formed with the chamber for the acceptance of the cathode. A laser weld connects the first and second parts of the shaft-shaped housing section together vacuum-tight.
