Poloidal and toroidal rotation has been recognized to play an important role in heat transport
and magnetohydrodynamic (MHD) stability in tokamaks and helical systems. It is well known …

Experimental observations of driven and intrinsic rotation in tokamak plasmas are reviewed.
For momentum sources, there is direct drive from neutral beam injection, lower hybrid and …

FIDASIM is a code that models signals produced by charge-exchange reactions between
neutrals and ions (both fast and thermal) in magnetically confined plasmas. With the ion …

We present the first measurement of a local fast-ion 2D velocity distribution function f (v||,
v⊥). To this end, we heated a plasma in ASDEX Upgrade by neutral beam injection and …

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 …

Detailed measurements of the main ion (${D}^{+} $) and impurity ion (${C}^{6+} $) evolution
during the development of the H-mode pedestal across an L–H transition show significant …

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 …

Main-ion charge exchange recombination spectroscopy (MICER) uses the neutral beam
induced D α spectrum to measure the local deuterium ion (D+) temperature, rotation, and …

The neutral-beam induced D α emission spectrum contains a wealth of information such as
deuterium ion temperature, toroidal rotation, density, beam emission intensity, beam neutral …

Charge-exchange spectroscopy on JET has become particularly challenging with the
introduction of the ITER-like wall. The line intensities are weaker and contaminated by many …
