Status and outlook of the neutron time-of-flight facility n_TOF at CERN
(2007-08)
Article
Accés restringit per política de l'editorialThe neutron time-of-flight facility n_TOF at CERN, fully operational since 2002, combines a high instantaneous neutron flux with high energy resolution. The wide energy range and the high neutron flux per time-of-flight ... -
Monte Carlo simulations for the study of a moderated neutron detector
(2011-08-12)
Article
Accés obertThis work presents the Monte Carlo simulations performed with the MCNPX and GEANT4 codes for the design of a BEta deLayEd Neutron detector, BELEN-20. This detector will be used for the study of beta delayed neutron emission ... -
Characterization of the new n_TOF neutron ream: fluence, profile and resolution
(2011-08-12)
Article
Accés restringit per política de l'editorialAfter a halt of four years, the n TOF spallation neutron facility at CERN has resumed operation in November 2008 with a new spallation target characterized by an improved safety and engineering design, resulting in a ... -
Neutron capture measuremetns on minor actinides at the n_TOF facility at CERN: past, present and future
(2011-08-12)
Article
Accés restringit per política de l'editorialThe successful development of advanced nuclear systems for sustainable energy production and nuclear waste management depends on high quality nuclear data libraries. Recent sensitivity stud- ies and reports [1-3] have ... -
Study of photon strength function of actinides: the case of 235-U, 238-Np and 241-Pu
(2011-08-12)
Article
Accés restringit per política de l'editorialThe decay from excited levels in medium and heavy nuclei can be described in a statistical approach by means of Photon Strength Functions and Level Density distributions. The study of electromagnetic cascades following ... -
The role of Fe and Ni for S-process nucleosynthesis and innovative nuclear technologies
(2011-08-12)
Article
Accés restringit per política de l'editorialThe accurate measurement of neutron capture cross sections of all Fe and Ni isotopes is important for disentangling the contribution of the s-process and the r-process to the stellar nucleosynthesis of elements in the mass ... -
Resonance neutron-capture cross sections of stable magnesium isotopes and their astrophysical implications
(2012-04-20)
Article
Accés restringit per política de l'editorialWe have measured the neutron capture cross sections of the stable magnesium isotopes 24,25,26Mg in the energy range of interest to the s process using the neutron time-of-flight facility n_TOF at CERN. Capture events ... -
ß-delayed neutron emission measurements around the third r-process abundance peak
(2012)
Comunicació de congrés
Accés restringit per política de l'editorialThe elements heavier than iron are produced in the Universe mainly by means of the slow (s) and rapid (r) neutron capture processes (for a recent review see e.g. [1]). The latter nucleosynthesis mechanism occurs between ... -
Measurement of the angular distribution of fission fragments using a PPAC assembly at CERN n_TOF
(2014-01-08)
Article
Accés restringit per política de l'editorialA fission reaction chamber based on Parallel Plate Avalanche Counters (PPACs) was built for measuring angular distributions of fragments emitted in neutron-induced fission of actinides at the neutron beam available at the ... -
Measurements of eye lens doses in interventional cardiology using OSL and electronic dosemeters
(2014-12-01)
Article
Accés obertThe purpose of this paper is to test the appropriateness of OSL and electronic dosemeters to estimate eye lens doses at interventional cardiology environment. Using TLD as reference detectors, personal dose equivalent was ... -

Direct growth of hydrotalcite nanolayers on carbon fibers by electrospinning
(2014-11-01)
Article
Accés restringit per política de l'editorialHydrotalcite (HT) nanolayers have been grown directly on carbon fibers by carbonization and subsequent hydration of electrospun PVA/PEO/MgAl-nitrate fibers. The growth of the layered material was ascertained by X-ray ...
