Kalman filter density reconstruction in ICRH discharges on ASDEX Upgrade

Federico Alberto Alfredo Felici, Emiliano Fable

Plasma density is one of the key quantities that need to be controlled in real-time as it scales directly with fusion power and, if left uncontrolled, density limits can be reached leading to a disruption. On ASDEX Upgrade (AUG), the real-time measurements ...

Impact of the plasma operation on the technical requirements in EU-DEMO

Olivier Sauter, Minh Quang Tran, Emiliano Fable, Simon Van Mulders

The plasma design point during stationary phase operation of EU-DEMO has been described extensively in the past, and the assumptions employed for its definition have been supported by various investigations. However, a stationary snapshot is by far not suf ...

Rapid electron internal transport barrier formation during magnetic shear reversal in fully non-inductive TCV discharges

Olivier Sauter, Stefano Coda, Timothy Goodman, Antoine Pochelon, Yann Camenen, Emiliano Fable, Costanza Zucca, Petri Nikkola

The rapid formation of an electron internal transport barrier (eITB) is observed during a slow evolution (similar or equal to 200 ms) from a centrally peaked to a hollow current density profile, while all external actuators remain constant. The time consta ...

Inductive current density perturbations to probe electron internal transport barriers in tokamaks

Olivier Sauter, Stefano Coda, Timothy Goodman, Roland Behn, Alberto Bottino, Emiliano Fable, Costanza Zucca, Andrei Martynov, Petri Nikkola

Improved electron energy confinement in tokamak plasmas, related to internal transport barriers, has been linked to nonmonotonic current density profiles. This is difficult to prove experimentally since usually the current profiles evolve continuously and ...
