Implementation of synthetic fast-ion loss detector and imaging heavy ion beam probe diagnostics in the 3D hybrid kinetic-MHD code MEGA
(American Institute of Physics, 2021-04-27)
A synthetic fast-ion loss (FIL) detector and an imaging Heavy Ion Beam Probe (i-HIBP) have been implemented in the 3D hybrid kinetic-magnetohydrodynamic code MEGA. First synthetic measurements from these two diagnostics ...

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 ...

Neutron capture cross section of 90Zr: Bottleneck in the s-process reaction flow
(The American Physical Society, 2008)
The neutron capture cross sections of the Zr isotopes have important implications in nuclear astrophysics and for reactor design. The small cross section of the neutron magic nucleus 90Zr, which accounts for more than 50% ...

Neutron capture cross section measurement of 151 Sm at the CERN neutron time of flight facility (n_TOF)
(American Physical Society, 2004-10-15)
The151Sm(n,γ)152Sm cross section has been measured at the spallation neutron facility n_TOF at CERN in the energy range from 1 eV to 1 MeV. The new facility combines excellent resolution in neutron time-of-flight, low ...

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 ...

Toward Prediction of Financial Crashes with a D-Wave Quantum Annealer
(MDPI, 2023)
Prediction of financial crashes in a complex financial network is known to be an NP-hard problem, which means that no known algorithm can guarantee to find optimal solutions efficiently. We experimentally explore a novel ...

Neutron-induced fission cross section of 245 Cm: New results from data taken at the time-of-flight facility n_TOF
(American Physical Society, 2012)
The neutron-induced fission cross section of 245Cm was measured at n-TOF in a wide energy range and with high resolution. The energy dependence, measured in a single measurement from 30 meV to 1 MeV neutron energy, has ...

Measurement of the 236U(n,f) cross section from 170 meV to 2 MeV at the CERN n_TOF facility
(American Physical Society, 2011)
The neutron-induced fission cross section of 236U was measured at the neutron Time-of-Flight (n-TOF) facility at CERN relative to the standard 235U(n,f) cross section for neutron energies ranging from above thermal to ...
