DISPOSITIF GENERATEUR D'ONDES MICROONDES A CATHODE VIRTUELLE OSCILLANTE, A GEOMETRIE AXIALE, COMPORTANT AU MOINS UN REFLECTEUR ET UNE BAGUE MAGNETIQUE, CONFIGURE POUR ETRE ALIMENTE PAR UN GENERATEUR A FORTE IMPEDANCE

摘要

The present application relates to a microwave wave generator with oscillating virtual cathode, with axial geometry, comprising at least one first reflector (F1) positioned in a cylindrical waveguide (105) downstream of a thin anode (104), positioned at the entrance of the cylindrical waveguide (105), between a cathode (102) and the cylindrical waveguide (105). The device furthermore comprises a tight magnetic ring (112) of width (LM) along the longitudinal axis z, positioned externally around the cylindrical waveguide (105), between the thin anode (104) and the first reflector (F1).
