Abstract

The study of the sheet-beam extended interaction oscillator, a compact, low voltage (~12kV) high power terahertz radition source is presented in this paper. In this structure, the sheet beam interacts with the electromagnetic mode of TM₃₁, 2π mode, and the generated electromagnetic wave is coupled and enhanced in the rectangle cavities. The sheet beam, high mode operation and rectangular cavity are helpful to enhance the beam-wave interaction, increase the frequency and the coupling strength, respectively. A 0.1THz cavity is designed, with cathode voltage of 12KV, beam current of 0.6A, and the guiding magnetic field strength of o.5T, simulation results show that the electromagnetic wave is generated with the frequency of 0.1THz and the peak power of 1kW at the output window.
