Roughness Evolution Induced by Third-Body Wear

Jean-François Molinari, Tobias Brink, Antonio Joaquin Garcia Suarez

Surface roughness is a key factor when it comes to friction and wear, as well as to other physical properties. These phenomena are controlled by mechanisms acting at small scales, in which the topography of apparently flat surfaces is revealed. Roughness i ...

Multipolar expansions for scattering and optical force calculations beyond the long wavelength approximation

Olivier Martin, Karim Achouri, Andrei Kiselev, Marco Riccardi

We review three different approaches for the calculation of electromagnetic multipoles, namely, the Cartesian primitive multipoles, the Cartesian irreducible multipoles, and the spherical multipoles. We identify the latter as the best suited to describe th ...

Determination of tungsten sources in the JET-ILW divertor by spectroscopic imaging in the presence of a strong plasma continuum

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Duccio Testa, Jonnathan Cesar Hidalgo Acosta, Jonathan Graves, Yves Martin, Li Shuai, Alberto Hernando de Castro

The identification of the sources of atomic tungsten and the measurement of their radiation distribution in front of all plasma-facing components has been performed in JET with the help of two digital cameras with the same two-dimensional view, equipped wi ...

Wavelength control in fabrication of wafer fused VCSELs emitting in the 1310 nm waveband

Elyahou Kapon, Grigore Suruceanu, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Zlatko Mickovic

Emission wavelength setting of 1310nm-waveband VCSELs designed for coarse wavelength division multiplexing (CWDM) 4x10 Gbps fiber-optics transmission can be controlled thanks to the wafer fusion fabrication approach. This approach allows performing the cav ...

Planck 2013 results. XVII. Gravitational lensing by large-scale structure

Julien Lesgourgues, Fabio Finelli

On the arcminute angular scales probed by Planck, the cosmic microwave background (CMB) anisotropies are gently perturbed by gravitational lensing. Here we present a detailed study of this effect, detecting lensing independently in the 100, 143, and 217 GH ...

Gyrokinetic transport relations for gyroscale turbulence

Laurent Villard, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Thibaut Vernay

We derive explicit local transport relations for the global gyrokinetic formalism at arbitrary wavelength. This is an extension of the analysis in Scott et. al. 2010 where this was examined in the long-wavelength limit. Deriving a local expression for the ...
