Abstract
A system is described for introducing microwave power into the vacuum chamber of a tokamak for preionization of the gaseous medium located there in order to facilitate subsequent discharge in it. Three main problems arising in this case are considered and a way to solve them is proposed. The calculation model of the electromagnetic structure includes a mode converter, a dielectric transformer, and a galvanic isolation unit. All geometric parameters of the device components were optimized. The described microwave power input device is made of nonmagnetic stainless steel and is currently used at the MEPhI training and demonstration tokamak.
期刊介绍：
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
