  Term: Kink Mode
  Definition: Class of MHD instabilities which sometimes develop in a thin plasma column carrying a strong axial current. If a kink begins to develop in such a column the magnetic forces on the inside of the kink become larger than those on the outside, which leads to growth of the perturbation. The column then becomes unstable and can be displaced into the walls of the discharge chamber, causing a disruption.
