Large-orbit M-type oscillator with the adiabatic electron-optical system

A W-band sixth-harmonic magnetron-type slotted peniotron

“…Since the electrons interact with the RF fields fringing from the slot gaps, they should orbit fairly close to the vanes for strong interaction. 15,16 In the magnetron waveguide, the electric and magnetic components of the electromagnetic wave within the inner radius are defined by …”

THz-Range Spatial-Harmonic Magnetrons

“…The operation of THz-range spatial harmnonic magnetrons in the drift-orbital resonance mode has been analytically evaluated. The estimates based upon the drift-orbital resonance concept indicated that utilization of large-orbit electrons beams formed by a side gun [14] can be thought of as an optimal alternative permitting of exciting self-sustained oscillation in THz-range M-type devices. Fig.3 As seen from the foregoing, the results from the given analytical estimates of the THz-range SHM-TF performance for a frequency of 0.24 THz are not very much at variance with those of physical and numerical experiment (see Fig.1, Table 1).…”
