Negative triangularity scenarios: from TCV and AUG experiments to DTT predictions

Olivier Sauter, Stefano Coda, Justin Richard Ball, Matteo Vallar, Filippo Bagnato, Alessandro Balestri

Experiments, gyrokinetic simulations and transport predictions were performed to investigate if a negative triangularity (NT) L-mode option for the Divertor Tokamak Test (DTT) full-power scenario would perform similarly to the positive triangularity (PT) H ...

Overview of the first Wendelstein 7-X long pulse campaign with fully water-cooled plasma facing components

Joaquim Loizu Cisquella, Mike Machielsen

After a long device enhancement phase, scientific operation resumed in 2022. The main new device components are the water cooling of all plasma facing components and the new water-cooled high heat flux divertor units. Water cooling allowed for the first lo ...

Design Space of Negative Capacitance in FETs

Jean-Michel Sallese, Farzan Jazaeri

Relying on the previously developed charge-based approaches, this paper presents a physics-based design space of negative capacitance in double-gate and bulk MOSFET architectures. The impact of thickness variation of the ferroelectric on the DC characteris ...

Reduction of PdO/Al2O3 in Liquid Cyclohexane Followed In Situ by ATR-IR, High-Energy XRD, and XAS

Oliver Kröcher, Davide Ferri, Thibault Xavier Florian Fovanna

Supported Pd-based catalysts used in heterogeneously catalyzed liquid phase processes often undergo an activation step through reduction of the oxide phase or of the oxidic passivation layer prior to reaction. An oxidized Pd/Al2O3 catalyst was reduced by u ...

Quench Simulation of REBCO Cable-in-Conduit Conductor With Twisted Stacked-Tape Cable

Pierluigi Bruzzone, Rainer Wesche, Kamil Sedlák, Davide Uglietti

Quench protection is a critical issue for magnet using high-temperature superconducting (HTS) materials such as REBCO. For cable-in-conduit conductor (CICC) with twisted REBCO tapes, which is considered for high-current HTS conductor for fusion magnet, the ...
