thermionic electric converter includes a power converter, a thermionic emission cathode laser enhanced (374) adapted to direct a laser beam (9) in such a way that it is on a surface of a cathode emitter u00e9missive (321), in order to increase the emiss electron ion emitter cathode (321).the laser strengthening of emission of cathode (374) is positioned to direct a laser beam (2) through an opening (370) to the anode (306) and the target structure in the direction of the cathode emitter (321).a ring of electron repulsion (380) is placed at a side of the opening (370) to the anode (306) to reduce the number of electrons is the anode (306) and passes through the opening (370) to the anode (306).
