The ion temperature gradient (ITG) instability is a microinstability in [[tokamak]]s relevant to turbulence and the associated [[anomalous transport]]. | The ion temperature gradient (ITG) instability<ref> P. N. Guzdar, Liu Chen, W. M. Tang and P. H. Rutherford, ''Ion‐temperature‐gradient instability in toroidal plasmas'' [[doi:10.1063/1.864182|Phys. Fluids '''26''' (1983) 673]]</ref> is a microinstability in [[tokamak]]s relevant to turbulence and the associated [[anomalous transport]]. | ||
The instability occurs due to the nature of Grad-B drift. The Grad-B drift velocity of a particle (caused by a gradient in the magnetic field) is proportional to the particle's kinetic energy. Hotter particles drift further than colder particles. | The instability occurs due to the nature of Grad-B drift.
