Organization of experiments on HF plasma heating on the spherical Globus-M tokamak at frequencies more ion cyclotron frequency

The organization of the experiments on the HF plasma heating at the spherical tokamak Globus-M at the frequencies by several times exceeding the ion cyclotron one, is considered. The results of the theoretical consideration of this problem through the unidimensional and two-dimensional codes, are presented. It is shown, that the single-passage absorption of the fast magneto-acoustic waves by the parameters, practically achievable at the facility, reaches 60%. The energy release thereby takes place in the near-axial plasma area. The single-loop antenna radiation resistance should be close to 1 Ω. The antenna design, making it possible to correlate the HF generator with the load is described and the antenna resonator parameters, necessary for the antenna operation optimization, are presented
