Abstract: In this contribution we presented a new simple technique for determination of tokamak plasma displacement based on poloidal flux measurement. This instrument consists of a two semicircle loops which installed toroidally on inner and outer sides of tokamak chamber and connected with each other. Really, this instrument detects the difference of poloidal flux on the High Field Side (HFS) and Low Field Side (LFS) of tokamak chamber, which we needed in calculating of the Plasma displacement. Main benefit of our proposed instrument is its simplicity. Based on this technique we determined the plasma position, and to compare the result obtained using this technique, an array of four magnetic probes and two flux loops are also designed, constructed and installed on outer surface of the IR-T1 tokamak and plasma position obtained from them. Results are in good agreement with analytical solution of equilibrium problem.
