In the field-reversed configuration (FRC) plasma, rotational instability with toroidal mode number n = 2 is known as a sole destructive MHD instability. Though an ideal FRC is unstable for higher n interchange instabilities, those have never been observed in past experiments. As a possible stabilized mechanism, self-generated toroidal rotation and its shear have been investigated experimentally.
