Example Embodiment

[0049] The invention relates to a dual-frequency radial continuous wave terahertz oblique injection tube capable of generating electromagnetic waves of two frequencies at the same time under low voltage conditions. The device adopts two fan-shaped electron beams that are transmitted in the opposite radial direction and two different sizes. With the sector-shaped metal flat plate slow-wave structure, the device can simultaneously generate two electromagnetic waves with a frequency greater than 0.1 terahertz and an output power greater than 1 watt in a continuous wave operating state in the terahertz band.

[0050] In the following, the present invention will be described in detail by taking the simultaneous generation of 0.305 terahertz and 0.34 terahertz electromagnetic waves as an example:

[0051] The device can generate 0.305 terahertz and 0.34 terahertz electromagnetic waves at the same time when the radial guidance magnetic field amplitude is 0.6 Tesla and the axial guidance ma...

Abstract

The invention relates to a double-frequency radial continuous wave Terahertz inclined injection pipe which comprise an axially symmetrical metal top plate, an axially symmetrical metal base plate, two sector-shaped electron beams, two sector-shaped metal flat slow wave structures, a coaxial output waveguide outer cylinder, a coaxial output waveguide inner cylinder, an axially symmetrical collector electrode and an external magnetic field generator; the external magnetic field generator generates a static magnetic field along radial and axial direction in a high-frequency interaction region, under guidance of the static magnetic field, the two sector-shaped electron beams are transmitted along the reverse of the radial direction, and interact with the two sector-shaped metal flat slow wave structures of different structural parameters respectively to convert kinetic energies of the two sector-shaped electron beams into electromagnetic wave energies in two different frequencies, electromagnetic waves in the two frequencies are radiated by the coaxial output waveguide, electromagnetic wave output in two different frequencies can be generated simultaneously, and the whole working frequency and tuning range of the pipe are broadened.

Description

technical field [0001] The invention belongs to the technical field of continuous wave terahertz vacuum electron radiation source, and specifically relates to a dual-frequency path that works in a continuous wave state and can simultaneously radiate two terahertz bands with frequencies greater than 0.1 terahertz and output power greater than 1 watt. Slant the tube into the continuous wave terahertz. Background technique [0002] In recent years, terahertz technology has been greatly developed, and a terahertz source with a certain power output is the basis for the application of terahertz technology. The terahertz source based on vacuum electronics can produce higher output power, so the research on vacuum electronics terahertz source devices is vigorously carried out at home and abroad. The terahertz pulse signal of 1.03THz and output power of 1kW, Fukuda University in Japan has carried out experimental research on the continuous wave gyrotron in the terahertz band. The N...
