Claim Text:
1. An energy extraction circuit for extracting energy from a charged-particle beam, comprising: a bidirectional converter couplable to an electrical power grid; and a bidirectional resonant converter comprising a multi-pole inverse cyclotron converter, an inductor electrically coupled to the multi-pole inverse cyclotron converter, and a plurality of circuit switches electrically coupled to the inductor and the multi-pole inverse cyclotron converter and electrically coupled to the bidirectional converter, the multi-pole inverse cyclotron converter includes two or more elongated plates with arcuate cross-sections forming an elongated cylindrical chamber with each of the two or more elongated plates forming a cylindrical segment of the cylindrical chamber with two or more elongated gaps formed between elongated edges of adjacent plates of the two or more plates and axially extending parallel to a longitudinal axis of the cylindrical chamber, wherein the two or more plates function as a capacitor which combined with the inductor forms a resonant tank, wherein the plurality of circuit switches are configured to form a bridge that chops direct current voltage received from the bidirectional converter to a pulse waveform, wherein the multi-pole inverse cyclotron converter when current is applied to the two or more elongated plates, forms a multi pole electric field across the gaps between the plates that decelerates charged particles of charged-particle beams passing through the cylindrical chamber to extract electric energy from the kinetic energy of the charged particles, wherein converted electrical energy received from the grid-tied bidirectional converter establishes the resonance of the multi-pole inverse cyclotron converter wherein the bidirectional converter and the plurality of circuit switches form an ac-to-ac converter between the resonant tank and the electrical power grid.
