Mixed diffusive-convective relaxation of a broad beam of energetic particles in cold plasma
Nakia Carlevaro, Alexander V. Milovanov, Matteo V. Falessi +3
We revisit the applications of quasi-linear theory as a paradigmatic model for weak plasma turbulence and the associated bump-on-tail problem. The work, presented here, is built ar…
Fast excitation of geodesic acoustic mode by energetic particle beams
Jintao Cao, Zhiyong Qiu, Fulvio Zonca
A new mechanism for Geodesic acoustic mode (GAM) excitation by a not fully slowed down energetic particle (EP) beam is analysed to explain experimental observations in Large Helica…
The role of MHD in causing impurity peaking in JET Hybrid plasmas
T. C. Hender, P. Buratti, F. J. Casson +10
In Hybrid plasma operation in JET with its ITER-like wall (JET-ILW) it is found that n>1 tearing activity can significantly enhance the rate of on-axis peaking of tungsten impuriti…
Linear gyrokinetic particle-in-cell simulations of Alfven instabilities in tokamaks
A. Biancalani, A. Bottino, S. Briguglio +6
The linear dynamics of Alfven modes in tokamaks is investigated here by means of the global gyrokinetic particle-in-cell code NEMORB. The model equations are shown and the local sh…
Nonlinear Energetic Particle Transport in the Presence of Multiple Alfvenic Waves in ITER
Mirjam Schneller, Philipp Lauber, Sergio Briguglio
This work presents the results of a multi mode ITER study on Toroidal Alfven Eigenmodes, using the nonlinear hybrid HAGIS-LIGKA model. It is found that main conclusions from earlie…
Improved Confinement in JET High {beta} Plasmas with an ITER-Like Wall
C. D. Challis, J. Garcia, M. Beurskens +18
The replacement of the JET carbon wall (C-wall) by a Be/W ITER-like wall (ILW) has affected the plasma energy confinement. To investigate this, experiments have been performed with…
