Abstract
A magnetron includes a cathode and a vacuum envelope in which the cathode extends. The vacuum envelope includes a portion extending radially relative to the axis of the cathode. A pair of electrically conducting support arms for supporting the cathode are in electrical connection with cathode supply terminals. The support arms have free ends connected to the cathode by leads. A wall extends across an area of the radially-extending portion. The wall is positioned along the radially-extending portion nearer to an end of the radially-extending portion that is adjacent to the cathode than to an end that is remote from the cathode and the support arms are mounted in the wall.
