Application of gyrotrons in research and industrial technologies

Summary form only given. The creation of gyrotrons (sources of high-power electromagnetic radiation in the millimeter wavelength range) reveals new possibilities for development of efficient tools for scientific experiments and promising technologies for industrial material processing. This presentation reviews the physical basics of gyrotron applications including plasma heating and current drive in magnetic fusion setups, the creation of sources of dense plasma and beams of multi-charge ions, the deposition of polycrystalline diamond films by the CVD method, and the annealing of semiconductor structures.
