In an electron tube with coaxial electrodes comprising an anode, a cathode and at least one grid, the base of each electrode being connected to the outside through a connection, there is mounted between the base of the grid and said connection a solid annular piece having a duct for the passage of a cooling fluid, said duct being connected to at least one fluid inlet tube and one fluid outlet tube.
Claims4
An electron tube comprising
- coaxial electrodes including an anode, a cathode, and at least a control grid having a base portion,
- means forming with said electrodes a tube envelope,
- a separate electrical connection for each electrode extending outside the tube envelope, and
- means inside the tube envelope for interconnecting the base portion of the control grid and its electrical connection and including means for circulating cooling fluid therethrough for cooling the junction between the base of the control grid and its electrical connection.
