Abstract
A resonant cavity (49) which facilitates coupling to another resonant cavity includes walls (40, 42) and an electrically conducting mast (43). One of the walls (40) has a coupling orifice (41) for coupling the resonant cavity (49) to another resonant cavity. The electrically conducting mast (43) projects from the second wall (42) opposite the first wall (40) and faces the coupling orifice (41). The electrically conducting mast (43) terminates with a hook-shaped portion (44) which contacts an edge of the coupling orifice (41). The resonant cavity (49) is suited for applications requiring secondary output cavities coupled to inductive output tubes.
Claims19
A resonant cavity delimited by walls comprising:
- a first wall having a coupling orifice therein to couple said resonant cavity to another cavity;
- a second wall opposite the first wall;
- and
- an electrically conducting mast projecting from the second wall, said electrically conducting mast terminating at one end thereof with a hook-shaped portion, the hook-shaped portion being in contact with an edge of the coupling orifice, another end of the electrically conducting mast being in contact with the second wall;
- wherein said electrically conducting mast faces the coupling orifice from said second wall to said first wall.
An electron beam tube comprising:
- at least one cavity through which an electron beam passes;
- and
- a resonant cavity coupled to the at least one cavity through which the electron beam passes, said resonant cavity including,
- a first wall having a coupling orifice therein to couple said resonant cavity to said at least one cavity,
- a second wall opposite the first wall, and
- an electrically conducting mast, projecting from the second wall and towards the coupling orifice, the electrically conducting mast terminating at one end thereof with a hook-shaped portion, the hook-shaped portion being in contact with an edge of the coupling orifice, another end of the electrically conducting mast being in contact with the second wall.
