96 Zr(n,γ) measurement at the n_TOF facility at CERN
(American Physical Society, 2011)
The (n,γ) cross section of 96Zr has been investigated at the CERN n-TOF spallation neutron source. High-resolution time-of-flight measurements using an enriched ZrO2 sample allowed us to analyze 15 resonances below 40 keV ...

Measurement of resolved resonances of 232Th(n, γ) at the n_TOF facility at CERN
(American Physical Society, 2012)
The yield of the neutron capture reaction 232Th(n,γ) has been measured at the neutron time-of-flight facility n-TOF at CERN in the energy range from 1 eV to 1 MeV. The reduction of the acquired data to the capture yield ...

Extensions to the charge exchange recombination spectroscopy diagnostic suite at ASDEX Upgrade
(AIP Publishing, 2017)
A new core charge exchange recombination spectroscopy diagnostic has been installed in the ASDEX Upgrade tokamak that is capable of measuring the impurity ion temperature, toroidal rotation, and density on both the low ...

197Au(n,γ) cross section in the resonance region
(The American Physical Society, 2010)
The (n,γ) cross section of 197Au has been measured at n-TOF in the resolved resonance region, up to 5keV, with the aim of improving the accuracy in an energy range where it is not yet considered standard. The measurements ...

The 139 La(n ,γ) cross section: Key for the onset of the s -process
(The American Physical Society, 2007)
The nuclear resonance parameters and the capture cross section of the neutron magic isotope La139 have been measured relative to Au197 in the energy range of 0.6 eV to 9 keV at the neutron time-of-flight (n_TOF) facility ...

Neutron capture on 94Zr: Resonance parameters and Maxwellian-averaged cross sections
(American Physical Society, 2011)
The neutron capture cross sections of the Zr isotopes play an important role in nucleosynthesis studies. The s-process reaction flow between the Fe seed and the heavier isotopes passes through the neutron magic nucleus ...

Neutron physics of the Re/Os clock. III. Resonance analyses and stellar (n, γ) cross sections of 186, 187, 188Os
(The American Physical Society, 2010)
Neutron resonance analyses have been performed for the capture cross sections of 186Os, 187Os, and 188Os measured at the n-TOF facility at cern. Resonance parameters have been extracted up to 5, 3, and 8 keV, respectively, ...

Divertor, scrape-off layer and pedestal particle dynamics in the ELM cycle on ASDEX Upgrade
(IOP Publishing, 2018)
In addition to the relaxation of the pedestal, edge localised modes (ELMs) introduce changes to the divertor and scrape-off layer (SOL) conditions. Their impact on the inter-ELM pedestal recovery is investigated, with ...

Digital-analog quantum algorithm for the quantum Fourier transform
(American Physical Society, 2020-01-06)
Quantum computers will allow calculations beyond existing classical computers. However, current technology is still too noisy and imperfect to construct a universal digital quantum computer with quantum error correction. ...
