The “Krot” plasma facility, which combines a high-current accelerator (1.5 MeV, 10 kA, 100 ns), a set of high-power microwave oscillators, and a vacuum chamber of extremely large volume (10 m in length, 3 m in diameter), for obtaining a highly homogeneous plasma with a broad spectrum of diagnostics.
The “Krot” plasma facility
High-current electron accelerators equipped with X-ray protection, magnetic systems (with pulsed and superconducting solenoids), quasi-optical channels, diagnostic complexes, and automated systems for recording and processing of information. These include:
high-current accelerating complex (700 keV, 7 kA, 17 ns), which operates with high clock frequency (up to 100 Hz) and is designed for refinement of relativistic microwave oscillators used as the sources of high-power sounding pulses of electromagnetic radiation in experimental and test setups;
High-current electron accelerator with a microwave oscillator of the “Krot” facility
the “Sinus-6” setup with an electron energy of 0.5 MeV, 5 kA, 20 ns which is used for model studies of microwave sources and their separate units. “Sinus-6” intensifies research significantly due to the possibi-lity of rapidly varying the electron-beam parameters;
the “Saturn” setup with a thermo-emission injector for obtaining long-duration current pulses;
the CARM system (300 keV, 100 A, 10 μs, clock frequency up to 1 Hz), which is used to solve problems related to the creation of oscillators and amplifiers based on induced cyclotron radiation of relativistic electron beams. The thermo-emission electron gun used for these purposes generates high-quality electron beams with required configuration of the electron trajectories.
A set of experimental setups for studying high-power gyrotrons equipped with cryomagnets (having a maximum magnetic-field induction of 5.5 to 7 T), high-voltage power supplies, and an automated system of control and measuring equipment, which includesthree experimental setups for studying gyrotrons and gyroklystrons designed for various technological applications, including
the gyroklystrons for radars (at frequencies 35 and 94 GHz with an output pulse power of about 100 kW or more) and technological gyrotrons operated in the 24–30 GHz frequency range (using permanent magnets and “warm” solenoids) and at frequencies higher than 35 GHz (with superconducting magnetic systems);
a set of setups for studying spatial amplitude-phase structures of the electromagnetic fields of electrodynamic devices and high-power microwave tubes.

A complex for growing high-quality diamond films, which comprises a microwave CVD reactor that uses the pulsed microwave discharge plasma at a frequency of 2.45 GHz, a standard microwave CVD reactor with the use of a continuous microwave discharge at a frequency of 2.45 GHz, and an experimental setup for deposition of diamond films using microwave radiation of a CW gyrotron having a power of 10 kW at a frequency of 30 GHz.
Multifunctional facility based on ECR discharge maintained by the radiation of a high-power gyrotron in the magnetic trap under electron-cyclotron resonance conditions. The facility is used for the creation of soft X-ray radiation and high-current beams of multicharged ions with high brightness.
Experimental plasma-chemical system for semiconductor film deposition experiments using broadband (nitrides, carbides, etc,) and regular semiconductors (including isotopically modified ones) with micro- and nano-crystal structure based on an ECR discharge maintained by the radiation of a CW gyrotron having a power of 5 kW at a frequency of 24 GHz.
