Tractable flux-driven temperature, density, and rotation profile evolution with the quasilinear gyrokinetic transport model QuaLiKiz
Jonathan Citrin,Clarisse Bourdelle,F. J. Casson,Clemente Angioni,N. Bonanomi,Yann Camenen,Xavier Garbet,L. Garzotti,Tobias Görler,Özgür D. Gürcan,F. Koechl,F. Imbeaux,O. Linder,K. L. van de Plassche,Pär Strand,Gabor Szepesi,Jet Contributors +16 more
TL;DR: Bourdelle et al. as mentioned in this paper proposed a quasilinear turbulent transport model QuaLiKiz, which employs an approximated solution of the mode structures to significantly speed up computation time compared to full linear gyrokinetic solvers.
Journal ArticleDOI
Self-consistent simulation of plasma scenarios for ITER using a combination of 1.5D transport codes and free-boundary equilibrium codes
Vassili Parail,Raffaele Albanese,R. Ambrosino,Jean-Francois Artaud,K. Besseghir,M. Cavinato,G. Corrigan,J. Garcia,L. Garzotti,Y. Gribov,F. Imbeaux,F. Koechl,C. Labate,J.B. Lister,X. Litaudon,A. Loarte,P. Maget,Massimiliano Mattei,D. C. McDonald,Eric Nardon,G. Saibene,R. Sartori,Jakub Urban +22 more
TL;DR: In this article, a self-consistent transport simulation of all reference ITER scenarios and variants using two suites of linked transport and equilibrium codes is discussed, in particular with the poloidal field coil system, heating and current drive, fuelling and particle and energy exhaust systems.

Friedrich E. Wagner,A. Bécoulet,R.V. Budny,V. Erckmann,Daniela Farina,G. Giruzzi,Yutaka Kamada,A. Kaye,F. Koechl,K. Lackner,Nikolai B. Marushchenko,M. Murakami,T. Oikawa,V.V. Parail,Jin Myung Park,G. Ramponi,Olivier Sauter,D. Stork,P. R. Thomas,Q. M. Tran,D.J. Ward,H. Zohm,C. Zucca +22 more
TL;DR: In this article, the authors considered the heating mix of ITER for the two main scenarios and concluded that the present heating mix is appropriate. And they provided the necessary actuators to induce in a flexible way the best possible scenarios.

A. R. Polevoi,A. Loarte,Nobuhiko Hayashi,H.S. Kim,S.H. Kim,F. Koechl,A.S. Kukushkin,A.S. Kukushkin,A.S. Kukushkin,V. M. Leonov,S. Yu. Medvedev,S. Yu. Medvedev,M. Murakami,Yong-Su Na,Alexei Pankin,J.M. Park,P. B. Snyder,Joseph Snipes,V. E. Zhogolev +18 more
TL;DR: In this paper, the operational space (Ip − n) for long-pulse scenarios (Δtburn ~ 1000 s, Q ≥ 5) of ITER has been assessed by 1.5D core transport modelling with pedestal parameters predicted by the EPED1 code by a set of transport codes under a joint activity carried out by the Integrated Operational Scenario ITPA group.
