A new method for measuring a horizontal plasma position using Mirnov oscillations is presented. This method for detecting a plasma position uses either a phase difference between Mirnov coil signals or an amplitude ratio of Mirnov coil signals. Experimental results obtained in the HYBTOKII tokamak device are described. Here, Mirnov oscillations with poloidal and toroidal mode numbers m/n=2/1 are utilized. The horizontal plasma positions measured by using Mirnov coil signals are compared with those measured by using magnetic probe signals, and consistency between them is discussed.
