Inference of -particle density profiles from ITER collective Thomson scattering
Jesper Rasmussen, Morten Stejner, Thomas Jensen +6
The primary purpose of the collective Thomson scattering (CTS) diagnostic at ITER is to measure the properties of fast-ion populations, in particular those of fusion-born -parti…
Modelling the electron cyclotron emission below the fundamental resonance in ITER
Jesper Rasmussen, Morten Stejner, Lorenzo Figini +8
The electron cyclotron emission (ECE) in fusion devices is non-trivial to model in detail at frequencies well below the fundamental resonance where the plasma is optically thin. Ho…
Measurement of a 2D fast-ion velocity distribution function by tomographic inversion of fast-ion D-alpha spectra
Mirko Salewski, Benedikt Geiger, Asger Schou Jacobsen +12
We present the first measurement of a local fast-ion 2D velocity distribution function . To this end, we heated a plasma in ASDEX Upgrade by neutral beam i…
Doppler tomography in fusion plasmas and astrophysics
Mirko Salewski, Benedikt Geiger, Bill Heidbrink +13
Doppler tomography is a well-known method in astrophysics to image the accretion flow, often in the shape of thin discs, in compact binary stars. As accretion discs rotate, all emi…
Divorticity and Dihelicity In Two-Dimensional Hydrodynamics
B. K. Shivamoggi, G. J. F. van Heijst, J. Juul Rasmussen
A framework is developed based on the concepts of {\it divorticity} ($\equiv\nabla\times\bfo$, $\bfo$ being the vorticity) and $\textit{dihelicity} g \lp \equiv\bfv\cd…
Variational principle for the relativistic hydrodynamic flows with discontinuities, and local invariants of motion
A. V. Kats, J. Juul Rasmussen
A rigorous method for introducing the variational principle describing relativistic ideal hydrodynamic flows with all possible types of discontinuities (including shocks) is presen…
