Abstract

The paper describes an experimental facility for plasma physics and material science research. The system provides effective transportation of radiation from gyrotron output to the area under investigation inside the vessel, which can be arranged for specific task and equipped with different control and measurement tools. The use of this facility made it possible to realize a series of various experiments, in particular, initiating and studying the fundamental properties of a terahertz discharge, obtaining nanopowders by evaporation-condensation method, as well as measuring the dielectric properties of metal oxide powders. As a radiation source we used 0.26 THz/1 kW gyrotron, which can operate both in CW or pulse mode, gyrotron, the radiation of which can, if necessary, be focused by quasi-optical mirror into a spot with a diameter of about 2.5 mm, providing a power density of up to 20 kW/cm² in the region of interest. The main components of the facility are described and some results of recent experiments are given.
