Density gradient stabilization of electron temperature gradient driven turbulence in a spherical tokamak

Published

Journal Article

In this Letter we report the first clear experimental observation of density gradient stabilization of electron temperature gradient driven turbulence in a fusion plasma. It is observed that longer wavelength modes, kρs10, are most stabilized by density gradient, and the stabilization is accompanied by about a factor of 2 decrease in the plasma effective thermal diffusivity. © 2011 American Physical Society.
