Method of producing brazeless accelerating structures

A resonant apparatus comprising:

• a first waveguide having therein a first internal channel bounded by first internal walls, said first internal channel extending to and penetrating through a first distal end face of the first waveguide;
• a first knife edge having flat first inner sides terminating at a distal leading edge, said first inner sides being coincident with and parallel to said first internal walls so as to functionally extend said first internal walls without substantial interruption thereof;
• a second waveguide having therein a second internal channel bounded by second internal walls, said second internal channel extending to and penetrating through a flat proximal end face of the second waveguide;
• a second knife edge having flat second inner sides terminating at a proximal leading edge, said second inner sides being coincident with and parallel to said second internal walls so as to functionally extend said second internal walls without substantial interruption thereof;
• and
• a central component having a central opening, said central component being made from a metal that is softer than metals from which said knife edges are made;
• said first and second waveguides being assembled with said central component being sandwiched in between, such that said central opening extends between said first and second internal channels, and such that said first and second knife edges are pressed into opposing proximal and distal faces of said central component respectively, thereby simultaneously forming vacuum and RF seals between said first and second waveguides and said central component,
• said central component being an element that is functionally necessary to said resonant apparatus.
