Low-voltage Gyrotron as Simple Mm-Wave Source

2021 22nd International Vacuum Electronics Conference (IVEC) (2021)

Gyrotrons are commonly considered as expensive, bulky, and technically complicated devices due to high power, voltage, and high magnetic fields. However, if high output power is not needed, gyrotrons can look much simpler, and can operate at low voltage, despite the relativistic nature of induced cyclotron radiation explored. In this talk, the numerous theoretical and experimental results for low-voltage gyrotron operation are considered. Using accumulated experience, the feasibility of the millimeter-wave gyrotron with low voltage and power consumption is discussed.

Development of THz range CW gyrotrons at IAP RAS

2022 47th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz) (2015)

M. Yu. Glyavin A. V. Chirkov G. G. Denisov G. Yu. Golubyatnikov A. P. Fokin

Summary form only given. The CW/263 GHz gyrotron is developed at IAP RAS for future application as microwave power source in DNP/NMR spectrometers. The new experimental facility with computerized control was built to test this and subsequent gyrotrons. The maximum power up to 1 kW in 15 kV/0.4A operation regime has been obtained. The power about 10W, which looks enough for spectroscopy, was realized in low current 14 kV / 0.02A regime. The possibility of frequency tuning with variation of coolant temperature about 4 MHz / 1 degree was demonstrated. The spectrum width of the gyrotron is about 10 ^-6 . Next tubes with frequencies 527 GHz and 790 GHz are under development.

Development of a Vector Magnet Based on High-Temperature Superconductors for Working with Polarized Neutrons

Polarized neutron reflectometry is an experimental method for studying metallic thin heterophase layered materials, polymer films, biological systems, free liquide surfaces, and magnetic fluids. It requires experimental equipment that includes a special magnetic system. The described magnetic system, a vector magnet, will allow one to change the direction of the magnetic field in three directions, to place a temperature-control device inside at low and ultra-low temperatures, and will have an aperture that allows one to place a system for detecting neutrons and gamma radiation outside. According to calculations, the cryomagnet will allow the application of a maximum field of up to 3 T in the vertical plane, and of up to 1 T in the horizontal plane. It is proposed to use a 4 mm wide high-temperature superconductor tape to manufacture the vector magnet. A cryostat with a vector magnet will be installed on the REMUR reflectometer on the eighth channel of the IBR-2 reactor.

Development of highly efficient technological medium-power multi-frequency gyrotrons for plasma applications based on magnetically-shielded solenoids

M. D. Proyavin Vladimir Manuilov М. В. Морозкин Dmitry Sobolev M. Yu. Glyavin

Due to a growing interest for microwave radiation sources with a radiation frequency of several tens of GHz and output power of several tens of kW, we developed a new generation of technological gyrotron setups. The key feature of these systems is a novel magnetic system based on magnetically shielded solenoids (MSS). This magnetic system is several times more energy efficient than the common warm solenoids and it also allows to control the properties of the helical electron beam to make it interact with various cavity modes. The developed MSS provides a high field induction in the interaction space and a small stray field, so the gyrotron can operate in wide range of magnetic fields (from 1 T to 1.8 T in relatively low-consumption regime). It allows a gyrotron complex to operate within a wide frequency range (from 24 to 50 GHz on main cyclotron resonance). A total system efficiency expected to be about 35%, which is significantly higher than the existing analogs.
