Measurements of neutron cross sections for advanced nuclear energy systems at n_TOF (CERN)
(EDP Sciences, 2014)
The n_TOF facility operates at CERN with the aim of addressing the request of high accuracy nuclear data for advanced nuclear energy systems as well as for nuclear astrophysics. Thanks to the features of the neutron beam, ...

Recent results in nuclear astrophysics at the n_TOF facility at CERN
(Sissa Medialab, 2016)
The neutron time of flight (n_TOF) facility at CERN is a spallation source characterized by a white neutron spectrum. The innovative features of the facility, in the two experimental areas, (20 m and 185 m), allow for an ...

The neutron time-of-flight facility n-TOF at CERN: Phase II
(AIP Publishing, 2011)
Neutron-induced reactions are studied at the neutron time-of-flight facility n-TOF at CERN. The facility uses 6∼ns wide pulses of 20 GeV/c protons impinging on a lead spallation target. The large neutron energy range and ...

Dissemination of data measured at the CERN n TOF facility
(EDP Sciences, 2017)
The n TOF neutron time-of-flight facility at CERN is used for high quality nuclear data measurements from thermal energy up to hundreds of MeV. In line with the CERN open data policy, the n TOF Collaboration takes actions ...

The CERN n_TOF facility: a unique tool for nuclear data measurement
(EDP Sciences, 2016)
The study of the resonant structures in neutron-nucleus cross-sections, and therefore of the compound-nucleus reaction mechanism, requires spectroscopic measurements to determine with high accuracy the energy of the neutron ...

New measurement of the 242Pu(n,γ) cross section at n_TOF
(EDP Sciences, 2016)
The use of MOX fuel (mixed-oxide fuel made of UO2 and PuO2) in nuclear reactors allows substituting a large fraction of the enriched Uranium by Plutonium reprocessed from spent fuel. With the use of such new fuel composition ...

Measurement of the 240Pu(n,f) cross-section at the CERN n-TOF facility: First results from experimental area II (EAR-2)
(EDP Sciences, 2017)
The accurate knowledge of the neutron-induced fission cross-sections of actinides and other isotopes involved in the nuclear fuel cycle is essential for the design of advanced nuclear systems, such as Generation-IV nuclear ...

Performance of the reconstruction algorithms of the FIRST experiment pixel sensors vertex detector
(Elsevier, 2014)
Hadrontherapy treatments use charged particles (e.g. protons and carbon ions) to treat tumors. During a therapeutic treatment with carbon ions, the beam undergoes nuclear fragmentation processes giving rise to significant ...
