Description

A set of in-vessel saddle coils called dynamic resonant magnetic perturbation (DRMP) for generating rotating resonant magnetic perturbations has recently been constructed on the J-TEXT tokamak. The phenomenon of tearing mode locking to DRMP and rotating together with the DRMP field has been observed. There is an apparent decrease of the island width during the locking and unlocking procedure. Similar results are obtained in the numerical simulation. (brief communication)
