Manufacturing, installation, commissioning, and first results with the 3D low-temperature co-fired ceramic high-frequency magnetic sensors on the Tokamak a Configuration Variable

Duccio Testa

Innovative high-frequency magnetic sensors have been designed and manufactured in-house for installation on the Tokamak a Configuration Variable (TCV), which are now routinely operational during the TCV experimental campaigns. These sensors combine the Low ...

Results from the Alfven Eigenmode Active Diagnostic during the 2019-2020 JET deuterium campaign

Ambrogio Fasoli, Duccio Testa, Paulo Giovane Paschoali Pereira Puglia

This paper presents results of extensive analysis of mode excitation observed during the operation of the Alfven Eigenmode Active Diagnostic (AEAD) in the JET tokamak during the 2019-2020 deuterium campaign. Six of eight toroidally spaced antennas, each wi ...

Lower Hybrid Current Drive in High Aspect Ratio Tokamaks

Xiaoxia Bai, Joan Decker, Hoang-Trang Lam

A multi-machine study has been carried out to investigate the impact of a strongly bounded wave propagation domain on the Lower Hybrid current drive, a condition which occurs principally in high aspect ratio tokamaks. In this regime, the condition of kinet ...

Wall conditioning in fusion devices with superconducting coils

Stefano Coda

Wall conditioning is essential in tokamak and stellarator research to achieve plasma performance and reproducibility. This paper presents an overview of recent conditioning results, both from experiments in present devices and modelling, in view of devices ...

Mixed hydrogen-deuterium plasmas on JET ILW

Henri Weisen, Mikhail Maslov

A study of mixed hydrogen-deuterium H-mode plasmas has been carried out in JET-ILW to strengthen the physics basis for extrapolations to JET D-T operation and to support the development of strategies for isotope ratio control in future experiments. Variati ...

Investigation of turbulent transport regimes in the tokamak edge by using two-fluid simulations

Paolo Ricci, Maurizio Giacomin

The results of flux-driven, two-fluid simulations in single-null configurations are used to investigate the processes determining the turbulent transport in the tokamak edge. Three turbulent transport regimes are identified: (i) a developed transport regim ...

Real-time applications of Electron Cyclotron Emission interferometry for disruption avoidance during the plasma current ramp-up phase at JET

Matteo Fontana

Data produced by an electron cyclotron interferometer diagnostic are now available to the real-time control systems of of the joint European torus (JET) tokamak. The data consist of absolutely calibrated electron temperature profiles, covering the plasma l ...
