Advances in the physics basis for the European DEMO design

Ambrogio Fasoli, Javier García Hernández, Marco Wischmeier, Emiliano Fable, Bernhard Sieglin, Hartmut Zohm, Emanuele Poli

In the European fusion roadmap, ITER is followed by a demonstration fusion power reactor (DEMO), for which a conceptual design is under development. This paper reports the first results of a coherent effort to develop the relevant physics knowledge for tha ...

Suprathermal electron dynamics and MHD instabilities in a tokamak

Stefano Coda, Jonathan Graves, Joan Decker, Josef Kamleitner

The dynamics of suprathermal electrons in the presence of magnetohydrodynamics (MHD) activity and the excitation of MHD modes by suprathermal electrons are studied experimentally to improve the understanding of the interaction of fast particles with MHD in ...

Asymmetry in Size-Segregation Rates.

Christophe Ancey, Gaël Epely Chauvin, Kasper van der Vaart

We show experimentally and by comparison with theory that during particle size-segregation in a sheared granular flow large particles rise slower in regions of many small particles and small particles sink faster in regions of many large particles. Binary ...

Non-stationarity in experimental travel time measured in a lysimeter: theoretical and modeling lessons from a simplified hydrological system

Andrea Rinaldo, Enrico Bertuzzo, Pierre Claude Jean Queloz, Luca Carraro, Gianluca Botter

Experimental data have been collected over a year-long period in a large weighing lysimeter. Natural climatic forcing occurs, except for rainfall which is artificially generated as a given Poisson process at a daily timescale. A constant water table is mai ...

Fast and accurate CMB computations in non-flat FLRW universes

Julien Lesgourgues

We present a new method for calculating CMB anisotropies in a non-flat Friedmann universe, relying on a very stable algorithm for the calculation of hyperspherical Bessel functions, that can be pushed to arbitrary precision levels. We also introduce a new ...

Definition of the radiation fields for the JET gamma-ray spectrometer diagnostics

Patrick Blanchard

The JET gamma-ray diagnostics system provides information on the behaviour of fast particles within the tokamak plasma. Information on the spatial distribution of the interacting fast particles is obtained from the gamma-ray cameras, while energy distribut ...

Optical Coherence Correlation Spectroscopy (OCCS)

Theo Lasser, Christophe Pache, Marcel Leutenegger, Arno Pino Bouwens, Stefan Geissbühler, Daniel Pawel Szlag, Akihiro Sato, Stéphane Broillet

We present optical coherence correlation spectroscopy (OCCS), a novel method to study the motion dynamics of nanoparticles within many observation volumes simultaneously. For this purpose, OCCS combines the key features of dark-field optical coherence micr ...

Phase Anomalies in Micro-Optics

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We present a comprehensive review on the latest research activities that explore the Gouy phase and indicate the recent experimental progresses for its observations in studies that rely on a longitudinal-differential interferometer. The latter is a far-fie ...

COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses XII. Time delays of the doubly lensed quasars SDSS J1206+4332 and HS 2209+1914

Frédéric Courbin, Georges Meylan, Malte Tewes

Aims. Within the framework of the COSMOGRAIL collaboration we present 7- and 8.5-year-long light curves and time-delay estimates for two gravitationally lensed quasars: SDSS J1206+4332 and HS 2209+1914. Methods. We monitored these doubly lensed quasars in ...
