WebDiamagnetic frequency Solutions of the dispersion relation depend on three parameters Step 1: Determine the range of parameters for which each branch of the dispersion relation is unstable. Step 2: Determine the evolution of each parameter during the monster sawtooth. Step 3: Determine how the evolution of these parameters affect fishbones ... Weband low frequency fishbones. Aside from the fishbone branch and the ion branch, the internal kink mode dispersion relation has the "normal MHD" solution, the kink branch. The kink branch becomes unstable when the ideal growth rate y, is sufficiently high, causing sawteeth to occur (yj is defined as y s = -«> 4dW MHD, where co A is the Alfven ...

Webstabilization of the internal kink and the destabilization of the fishbone. The difference in the two approaches is reflected by the nature of the solution of the dispersion relation. To be … WebFishbone activity with frequencies around the precessional drift frequency of the fast ions Z~ ZDH [1] and the diamagnetic frequency of the bulk ions Z~ Z *i [2] have been observed in several tokamaks. In the first case, fishbone bursts occur when the precessional fishbone branch of the internal kink mode becomes unstable, while in the second case eye bolt with bushing
