Two experimental methods for the measurement of plasma displacement in an IR-T1 tokamak

In this paper, we measured plasma horizontal displacement using two experimental methods in the IR-T1 tokamak. First, two poloidal flux loops were designed and installed on the outer surface of the IR-T1 tokamak and were used to measure the Shafranov shift. Also, modified Rogowski and saddle sine coils based on the multipole moment method were designed, constructed and used. The results from these two methods are compared and are found to be in good agreement.
