Nuclear fusion technologies have re-gained momentum in the last decade thanks to their
disruptive potential in different fields, such as energy production and space propulsion, and …

Edge-localized-modes (ELMs) are a ubiquitous feature of H-mode in tokamaks. When
gradients in the H-mode transport barrier grow to exceed the MHD stability limit the ELM …

We demonstrate the measurement of a 2D MeV-range ion velocity distribution function by
velocity-space tomography at JET. Deuterium ions were accelerated into the MeV-range by …

Velocity-space tomography of the fast-ion distribution function in a fusion plasma is usually a
photon-starved tomography method due to limited optical access and signal-to-noise ratio of …

The velocity-space observation regions and sensitivities in fast-ion D α (FIDA) spectroscopy
measurements are often described by so-called weight functions. Here we derive …

High-resolution γ-ray spectroscopy (GRS) measurements resolve spectral shapes of
Doppler-broadened γ-rays. We calculate weight functions describing velocity-space …

One main programme topic at the ASDEX Upgrade all-metal-wall tokamak is development of
a high-density regime with central densities at reactor grade level while retaining high …

The spectral broadening of γ-rays from fusion plasmas can be measured in high-resolution
gamma-ray spectrometry (GRS). We derive weight functions that determine the observable …

Fast-ion D α (FIDA) and collective Thomson scattering (CTS) diagnostics provide indirect
measurements of fast-ion velocity distribution functions in magnetically confined plasmas …

Edge-localized mode (ELM) triggering and pacing in an all-metal wall environment shows
significant differences to a first-wall configuration containing carbon. Here we report on …
