Globus-M spherical tokamak

Abstract

The main parameters and design of the Globus-M spherical tokamak are described, including the modifications introduced after construction was completed. The experimental program and possibilities for optimizing the operating regimes of the facility are discussed. The research program envisages beginning with Ohmic heating experiments and continuing with work on rf heating and generation of drag currents. Recent results of modeling the propagation of rf waves in the 10–50 MHz and 2.45 GHz ranges are presented and the possibility of using these to control the profiles of the plasma parameters is discussed. A brief description is given of the primary diagnostics and the further development of the diagnostic complex is discussed.
