The calculations of the trajectory of microwave rays confirmed the possibility of using the peripheral part of the loudspeaker radiation to obtain important information about the plasma under study. It is shown that this part of the radiation can be used in U2-M). The study opens the way to use for measurements of plasma parameters that part of the loudspeaker radiation, which was usually considered useless, and sometimes even harmful. This allows the further use of methods of microwave diagnostics based on refraction on installations for magnetic retention of plasma (for example, stelarator U2-M), where it is not possible to change the angle of the horn antennas.  Product Description popup.authors KOZULYA Mykhaylo M.
