Jost, T. M. Tran, K. Appert, W. A. Cooper, and L. Villard, [http://www.ispp.it/Courses_and_Workshops.html in Theory of Fusion Plasmas, International Workshop, Varenna, September 1998 (Editrice Compositori, Società Italiana di Fisica, Bologna, 1999), p. 419.]</ref>. It allows three-dimensional turbulence simulations using a plasma equilibrium calculated with the [[VMEC]] code as a starting point. EUTERPE was further developed at the Max Planck IPP and several linear calculations of ion temperature gradient (ITG) driven turbulence in [[Tokamak|tokamak]] and [[Stellarator|stellarator]] geometry have been carried out using it | ||

Afterwards, the code has been heavily optimized and improved. The perturbation to the magnetic field, a third species (in adition to electrons and ions) and the non-linear dynamics have been included. | Afterwards, the code has been heavily optimized and improved.
