Instabilities due to Temperature Gradients in Complex Magnetic Field Configurations

摘要: An integral equation governing an instability due to ion temperature gradients is derived. In the presence of magnetic shear, localized non‐convective normal modes are shown exist if relative gradient larger than that density, unless shear exceedingly strong, i.e., field shears through a large angle in distance which drops. Quasi‐modes less direction can be constructed from these and thermal diffusion may expected. Conversely mass rather slow so it reasonable assume effective ``divertor'' should keep actual heat loss quite small.
