Experimental Observation of the Motion of Ions in a Resonantly Driven Plasma Wakefield Accelerator

Ambrogio Fasoli, Ivo Furno, Patrick Blanchard, Yanis Andrebe, Riccardo Agnello, Christine Stollberg

We show experimentally that an effect of motion of ions, observed in a plasma-based accelerator, depends inversely on the plasma ion mass. The effect appears within a single wakefield event and manifests itself as a bunch tail, occurring only when sufficie ...

First measurements of velocity-space resolved intra-ELM fast-ion losses on the TCV tokamak

Ambrogio Fasoli, Basil Duval, Benoît Labit, Alexander Karpushov, Mario Ludovico Podesta, Umesh Kumar, Jesús Poley Sanjuán

Edge Localised Modes (ELMs) induced fast-ion losses have been characterised in the energy, E, and pitch, λ = v ∥ / v , space using a unique Fast Ion Loss Detector (FILD) on the tokamak à configuration variable. The FILD is equipped with a 128 Avalanche Pho ...

Present status of heating neutral beam injection system at TCV

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Yves Martin, Patrick Blanchard, Alexander Karpushov, Damien Fasel, Yanis Andrebe, Matthieu Toussaint

The paper describes the operation and upgrade of the Heating Neutral Beam Injection (HNBI) system as well as the related infrastructure at the Tokamak Configuration Variable (TCV) during the last years. In 2023, the installation of new TCV neutron shieldin ...

Hosing of a Long Relativistic Particle Bunch in Plasma

Ambrogio Fasoli, Ivo Furno, Patrick Blanchard, Yanis Andrebe, Riccardo Agnello, Christine Stollberg, Sun Hee Kim, Alban Sublet, Shuai Liu

Experimental results show that hosing of a long particle bunch in plasma can be induced by wakefields driven by a short, misaligned preceding bunch. Hosing develops in the plane of misalignment, selfmodulation in the perpendicular plane, at frequencies clo ...

Isotope effects and Alfvén eigenmode stability in JET H, D, T, DT, and He plasmas

Ambrogio Fasoli

While much about Alfvén eigenmode (AE) stability has been explored in previous and current tokamaks, open questions remain for future burning plasma experiments, especially regarding exact stability threshold conditions and related isotope effects; the lat ...
