Abstract :
The time delay between magnetic coil signals in a tokamak is believed to lead to
inaccuracy in the measurement of the plasma physical parameters in the tokamak. In this
research, we calculated the time delay between the signals of magnetic coils used in IRT1
tokamak and investigated its effect on the measurement of the plasma horizontal
displacement. The time delay between the signals of the magnetic coils was calculated
utilizing time series analysis, and the horizontal displacement of the plasma was measured
using the multipole moments method. The experimental results showed that by
eliminating the time delay from the coil signals, the measurement of plasma horizontal
