The first observations of screening currents on multiple resonant surfaces have been made, and the transition from screening to field penetration has been measured. After RMP field penetration, the fluctuating part of the magnetic field has a significantly greater amplitude and a ∼180° phase difference compared to the vacuum case. This is possibly a result of the penetration of a 2/1 mode. The threshold for RMP field penetration is found to be lower when the DED field rotates in the counter-current direction since there is less difference between the intrinsic plasma rotation and the rotation of the DED field. |
