These phenomena occur at a local level when Suydam’s criterion is not met. These phenomena are less likely when q is above 1, a value known as the Kruskal-Shafranov limit. A phenomenon of this type that occurs in H-mode plasmas is modelled by a “peeling-ballooning” mechanism. The presence of these phenomena is decreased with higher magnetic shear. The field-reversed configuration is oddly resilient to these phenomena despite MHD predictions. These phenomena are commonly categorized by their m and n modes. These phenomena should not occur in theta pinches, but occur in z-pinches, primarily as “sausage” and “kink” varieties. These phenomena are likelier to occur when magnetic field curves towards the plasma, such as the “flute” form. That “flute” form of this phenomenon is a pressure-driven analogue of one that occurs when a fluid lies on top of a less dense fluid named for Rayleigh and Taylor. For 10 points, name these phenomena in plasmas where they are greatly affected by perturbations.
