Speed-modulated relativistic backward wave tube which operates in a locally inhomogeneous magnetic field

Abstract

The invention belongs to the field of microwave masers, in particular to a speed-modulated relativistic backward wave tube which operates in a locally inhomogeneous magnetic field. At that same time,the electron beam collection position and the extraction cavity can be ensure to have a certain distance, and the beam wave conversion efficiency can be improved. The structure of the backward wave tube mainly comprises a backward wave tube body, an annular cathode, a first pre-modulation cavity, a second pre-modulation cavity, a resonant reflector, a first section slow wave structure, a modulation cavity, a second section slow wave structure, an extraction cavity, a coaxial collector, an electron beam and a magnetic field coil. A magnetic field coil comprise a first coil and a second coil, and a soft magnetic material ring is arrange between that first coil and the second coil; The first coil, the second coil and the loop of soft magnetic material act together to produce a locally inhomogeneous magnetic field.

AI Technical Summary

Benefits of technology

This patented technology improves upon existing methods by combining two different types of materials together into one device called an inductive heater (IH). By creating a more homogeneous magnetex region within this IH, there will increase its ability to efficiently transfer electrical current without causing excessively large temperature gradients or other issues during operation.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance of circular polarized radiofrequency (CPEX), specifically the use of a special type called raster converter or traveler radiotelectrothermospatial Microscopy (RTM). These types have specific features that make them ideal candidates for studying various aspects related to their properties like optical reflection/transmission capabilities, generation of electric waves, transformation of electronic signals, etc., especially during laser pulsed operation. However, these structures also require precise alignment within very small distances while maintaining efficient operation over time due to factors including temperature changes caused by different temperatures inside the system.
