Be-7- and B-8-reaction dynamics at Coulomb barrier energies
(EDP Sciences, 2016)
We investigated the reaction dynamics induced by the Radioactive Ion Beams Be-7 and B-8 on a Pb-208 target at energies around the Coulomb barrier. The two measurements are strongly interconnected, being Be-7 (S-alpha = ...

Investigation of the 238U(d, p) surrogate reaction via the simultaneous measurement of γ -decay and fission probabilities
(American Physical Society, 2016)
We investigated the 238U(d,p) reaction as a surrogate for the n + 238U reaction. For this purpose we measured for the first time the γ -decay and fission probabilities of 239U∗ simultaneously and compared them to ...

The 92Zr(n,γ) reaction and its implications for stellar nucleosynthesis
(The American Physical Society, 2010)
Because the relatively small neutron capture cross sections of the zirconium isotopes are difficult to measure, the results of previous measurements are often not adequate for a number of problems in astrophysics and nuclear ...

Overview of progress in European medium sized tokamaks towards an integrated plasma-edge/wall solution
(IOP Publishing, 2017)
Integrating the plasma core performance with an edge and scrape-off layer (SOL) that leads to tolerable heat and particle loads on the wall is a major challenge. The new European medium size tokamak task force (EU-MST) ...

Measurement and analysis of the 243 Am neutron capture cross section at the n_TOF facility at CERN
(American Physical Society, 2014)
Background: The design of new nuclear reactors and transmutation devices requires to reduce the present neutron cross section uncertainties of minor actinides. Purpose: Improvement of the Am243(n,γ) cross section uncertainty. ...

Neutron physics of the Re/Os clock. I. Measurement of the (n, γ) cross sections of 186, 187, 188 Os at the CERN n_TOF facility
(The American Physical Society, 2010)
The precise determination of the neutron capture cross sections of 186Os and 187Os is important to define the s-process abundance of 187Os at the formation of the solar system. This quantity can be used to evaluate the ...

Recent ASDEX Upgrade research in support of ITER and DEMO
(IOP Publishing, 2015)
Recent experiments on the ASDEX Upgrade tokamak aim at improving the physics base for ITER and DEMO to aid the machine design and prepare efficient operation. Type I edge localized mode (ELM) mitigation using resonant ...

A rotary and reciprocating scintillator based fast-ion loss detector for the MAST-U tokamak
(American Institute of Physics, 2018)
The design and unique feature of the first fast-ion loss detector (FILD) for the Mega Amp Spherical Tokamak - Upgrade (MAST-U) is presented here. The MAST-U FILD head is mounted on an axially and angularly actuated mechanism ...

Hydrodynamic interactions induce anomalous diffusion under partial confinement
(Royal Society of Chemistry, 2014)
Under partial confinement, the motion of colloidal particles is restricted to a plane or a line but their dynamics is influenced by hydrodynamic interactions mediated by the unconfined, three-dimensional flow of the embedding ...

I-mode studies at ASDEX Upgrade: L-I and I-H transitions, pedestal and confinement properties
(IOP Publishing, 2017)
The I-mode is a plasma regime obtained when the usual L-H power threshold is high, e.g. with unfavourable ion B ∇ direction. It is characterised by the development of a temperature pedestal while the density remains ...
