ABSTRACT:
An exemplary system and method for providing a multi-layer klystron-type electron beam device for the generation and amplification of millimeter-wave electromagnetic radiation is disclosed as comprising inter alia: a cathode layer (130); a collector layer (100); an extraction layer (120); a control layer (140); an input cavity (150); an output cavity (170); several ceramic spacer layers (103, 105, 107) dispose intermediately between the cathode (130) and the collector (100); and optionally, several magnetic ceramic layers (160, 165) for beam forming and focusing. After the klystron's layers are assembled, the device may be fired to form a substantially monolithic structure.
