Abstract

This paper is dedicated an eddy current test research plan in order to evaluate the eccentricity for the sandwich structure conductor used in ITER in-vessel coils. Important parameters, such as signal, frequency, lift-off effect and probe direction, are analyzed by using a numerical simulation method, and sample experiments are carried out for verification. Eventually, optimized parameters will be the result from the data analysis and the experiment carried out.
