First results of the 241Am(n,f) cross section measurement at the Experimental Area 2 of the n_TOF facility at CERN
(EDP Sciences, 2020)
Feasibility, design and sensitivity studies on innovative nuclear reactors that could address the issue of nuclear waste transmutation using fuels enriched in minor actinides, require high accuracy cross section data for ...

7Be(n, p) 7Li Reaction and the Cosmological Lithium Problem: Measurement of the Cross Section in a Wide Energy Range at n_TOF at CERN
(APS Physics, 2018-07-24)
We report on the measurement of the 7Be(n,p)7Li cross section from thermal to approximately 325 keV neutron energy, performed in the high-flux experimental area (EAR2) of the n_TOF facility at CERN. This reaction plays a ...

First results of the 230Th(n,f) cross section measurements at the CERN n_TOF facility
(EDP Sciences, 2020)
The study of neutron-induced reactions on actinides is of considerable importance for the design of advanced nuclear systems and alternative fuel cycles. Specifically, 230Th is produced from the α-decay of 234U as a byproduct ...

Monte carlo simulations of the n-TOF lead spallation target with the Geant4 toolkit: A benchmark study
(EDP Sciences, 2017)
Monte Carlo (MC) simulations are an essential tool to determine fundamental features of a neutron beam, such as the neutron flux or the γ-ray background, that sometimes can not be measured or at least not in every position ...

The new vertical neutron beam line at the CERN n_TOF facility design and outlook on the performance
(Elsevier, 2015)
At the neutron time-of-flight facility n_TOF at CERN a new vertical beam line was constructed in 2014, in order to extend the experimental possibilities at this facility to an even wider range of challenging cross-section ...

Measurement of the 244Cm capture cross sections at both CERN n_TOF experimental areas
(EDP Sciences, 2020)
Accurate neutron capture cross section data for minor actinides (MAs) are required to estimate the production and transmutation rates of MAs in light water reactors with a high burnup, critical fast reactors like Gen-IV ...

Measurement of the 76 Ge ( n , γ ) cross section at the n_TOF facility at CERN
(American Physical Society, 2021)
The 76 Ge ( n , γ ) reaction has been measured at the n_TOF facility at CERN via the time-of-flight technique. Neutron capture cross sections on 76 Ge are of interest to a variety of low-background experiments, ...

80Se(n,?) cross-section measurement at CERN n TOF
(Institute of Physics Publishing, 2020)
Radiative neutron capture cross section measurements are of fundamental importance for the study of the slow neutron capture (s-) process of nucleosynthesis. This mechanism is responsible for the formation of most elements ...

Preliminary results on the 233U capture cross section and alpha ratio measured at n_TOF (CERN) with the fission tagging technique
(EDP Sciences, 2019)
233U is of key importance among the fissile nuclei in the Th-U fuel cycle. A particularity of 233U is its small neutron capture cross-section, which is on average about one order of magnitude lower than the fission ...

New reaction rates for the destruction of 7Be during big bang nucleosynthesis measured at CERN/n_TOF and their implications on the cosmological lithium problem
(EDP Sciences, 2020)
New measurements of the 7Be(n,α)4He and 7Be(n,p)7Li reaction cross sections from thermal to keV neutron energies have been recently performed at CERN/n_TOF. Based on the new experimental results, astrophysical reaction ...
