Abstract
A crossed-field device having a plurality of slow wave energy propagating structures, each with an associated cathode, requires relatively low voltage for operation to provide a high power output. Electron beam current control is achieved by means of RF drive signals. Periodic permanent magnet focusing is utilized.
Claims6
A crossed-field traveling wave electron interaction device comprising:
- an envelope;
- a plurality of axially aligned electrically coupled energy amplifier stages in a cascade array disposed within said envelope;
- each of said cascaded stages comprising a slow wave structure for propagating electromagnetic wave energy having input and output energy coupling means;
- and
- plural means for generating and directing electrons along a path adjacent to each said slow wave structure to interact in energy exchanging relation with said propagating wave energy;
- means for providing mutually perpendicular electric and magnetic fields along said interaction paths;
- means for coupling electromagnetic wave energy drive signals to said input coupling means of a first of said cascade stages to initiate operation;
- means for intercoupling wave energy signals from the output coupling means of said first stage to subsequent stage input coupling means to sequentially cause operation of each succeeding stage;
- and
- means for coupling the combined energy amplified output signals from the output coupling means of the last stage in the array to a utilization load.
