A millimeter wave relativistic backward wave oscillator operating in TM03 mode with low guiding magnetic field
TL;DR: In this paper, a V-band overmoded relativistic backward wave oscillator (RBWO) guided by low magnetic field and operating on a TM03 mode is presented to increase both the power handling capacity and the wave-beam interaction conversion efficiency.

Research on the Emission Uniformity of Explosive Emission Cathodes in Foilless Diodes
TL;DR: In this paper, the defects with dimensions of tens of micrometers on cathode surfaces, especially at blade edges, are removed to improve the emission uniformity of annular graphite cathodes in a foilless diode.

TL;DR: In this article, the initial stage of RF breakdown in high-power microwave (HPM) generators with a strong external guiding magnetic field has been carefully analyzed, and feasible solutions include lowering the local field strength, decreasing the energy of the field-emitted electrons obtained from the RF field, reducing the deposited energy density, and improving the material's resistance to electron bombardment.

Effective suppression of pulse shortening in a relativistic backward wave oscillator
TL;DR: In this article, a C-band relativistic backward wave oscillator (RBWO) was used to suppress high-power microwave (HPM) generation, and it was shown that a coaxial collector can effectively suppress plasma effects by retarding their axial and radial expansions.

Over-Sized Mode-Selective Relativistic Backward Wave Oscillator
TL;DR: In this article, an oversized mode-selective relativistic backward wave oscillator is proposed, which operates using the pure TM02 mode in the beam-wave interaction area and transmits a pure TM01 mode to the output waveguide.
