MEASUREMENTS OF LOOP ANTENNA LOADING IN RF HEATING EXPERIMENTS ON THE KT 5C TOKAMAK

A new method to measure the loop antenna loadings in the RF wave heating experiments (IBWH at resonable RF power with relatively low frequency) on the KT 5C device is presented. The method is characterized by determing the RF current ratio only, so it eases the needs of instruments and simplifies the requirements for calibration and data processing in the experiments.
