Abstract
Ion cyclotron resonance heating is considered as one of the methods of additional heating of plasma and production of the non-inductive current in the T-15MD tokamak. To transfer the maximum power to the plasma, it is needed to know impedance of an antenna–plasma system, to match it with impedance of an RF power generator and its transmission line. The work is devoted to the development of a code for the calculation of antenna impedance of the ICR heating system of plasma in toroidal magnetic traps. To find impedance of the antenna–plasma system in the simplified geometry of antenna consisting of conductive plates, the wave equation is solved in the “cold” plasma approximation, and the spectrum of the RF power emitted by antenna is calculated. The dependences of the impedance of the antenna–plasma system on distances between antenna and the Faraday screen and between the Faraday screen and the plasma are obtained for the geometry of the T-15MD tokamak. Two-dimensional distribution of electric field of a wave in the plasma is obtained.
期刊介绍：
Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
