Advances in the physics studies for the JT-60SA tokamak exploitation and research plan

Stefano Coda, Javier García Hernández, Aylwin Iantchenko, Marco Wischmeier, Matteo Vallar, Kenji Tanaka, Samuele Mazzi, Leonardo Pigatto

JT-60SA, the largest tokamak that will operate before ITER, has been designed and built jointly by Japan and Europe, and is due to start operation in 2020. Its main missions are to support ITER exploitation and to contribute to the demonstration fusion rea ...

Extension of the operating space of high-beta(N) fully non-inductive scenarios on TCV using neutral beam injection

Olivier Sauter, Timothy Goodman, Duccio Testa, Alexander Karpushov, Antoine Pierre Emmanuel Alexis Merle, Mengdi Kong, Javier García Hernández, Matteo Vallar, Leonardo Pigatto

The fully non-inductive sustainment of high normalized beta plasmas (beta(N)) is a crucial challenge for the steady-state operation of a tokamak reactor. In order to assess the difficulties facing such scenarios, steady-state regimes have been explored on ...
