1. A vacuum electron device for a radio-frequency (RF) amplifier or oscillator, comprising:
a first non-magnetic conductor plate;
a second non-magnetic conductor plate;
a plurality of non-magnetic interaction structure forming plates disposed between the first non-magnetic conductor plate and the second non-magnetic conductor plate, the plurality of non-magnetic interaction structure forming plates together forming an RF interaction structure housing an electron beam tunnel region, the first non-magnetic conductor plate, the second non-magnetic conductor plate and the plurality of non-magnetic interaction structure forming plates being bonded together;
permanent magnets arranged about the electron beam tunnel region to apply RF interaction to confine an electron beam within the electron beam tunnel region; and
at least one control plate electrically insulated from the RF interaction structure, the at least one control plate coupled to at least one electrically insulated conductor arranged to pass through and be electrically insulated from the RF interaction structure, the at least one electrically insulated conductor configured to apply a corrective steering or focusing force on the electron beam within the electron beam tunnel region.
