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…
Improved Collective Thomson Scattering measurements of fast ions at ASDEX Upgrade
J. Rasmussen, S. K. Nielsen, M. Stejner +12
Understanding the behaviour of the confined fast ions is important in both current and future fusion experiments. These ions play a key role in heating the plasma and will be cruci…
Conductance of single-atom platinum contacts: Voltage-dependence of the conductance histogram
S. K. Nielsen, Y. Noat, M. Brandbyge +6
The conductance of a single-atom contact is sensitive to the coupling of this contact atom to the atoms in the leads. Notably for the transition metals this gives rise to a conside…
