Collisions of Nucleons with Atoms: Calculated Cross Sections and Monte Carlo Simulation
(Frontiers Media S.A., 2021)
After a summary description of the theory of elastic collisions of nucleons with atoms, we present the calculation of a generic database of differential and integrated cross sections for the simulation of multiple elastic ...

Neutron-induced cross section measurements
(EPJ Web of Conferences, 2023)
Neutron-induced cross sections represent the main nuclear input to models of stellar and Big-Bang nucleosynthesis. While (n, gamma) reactions are relevant for the formation of elements heavier than iron, (n,p) and (n,alpha) ...

New detection systems for an enhanced sensitivity in key stellar (n,gamma) measurements
(E D P Sciences, 2023)
Neutron capture cross-section measurements are fundamental in the study of astrophysical phenomena, such as the slow neutron capture (s-) process of nucleosynthesis operating in red-giant and massive stars. However, neutron ...

Continuous and Pulsed Fast Neutron Beams at the CNA HiSPANoS Facility
(Elsevier, 2024)
The characteristics of the fast neutron beams produced in the HiSPANoS facility at Centro Nacional de Aceleradores (CNA) are presented. The neutrons are generated by deuteron beams from a 3 MV tandem accelerator in either ...

New perspectives for neutron capture measurements in the upgraded CERN-n_TOF Facility
(E D P Sciences, 2023)
The n_TOF facility has just undergone in 2021 a major upgrade with the installation of its third generation spallation target that has been designed to optimize the performance of the two n_TOF time-of-flight lines. This ...

Overview of the dissemination of n_TOF experimental data and resonance parameters
(EDP Sciences, 2023)
The n_TOF neutron time-of-flight facility at CERN is used for nuclear data measurements. The n_TOF Collaboration works closely with the Nuclear Reaction Data Centres (NRDC) network to disseminate the experimental data ...

Measurements of high-energy neutron-induced fission of natPb and 209Bi
(EDP Sciences, 2010)
The CERN Neutron Time-Of-Flight (n_TOF) facility is well suited to measure low cross sections as those of neutron-induced fission in subactinides. The cross section ratios of natPb and 209Bi relative to 235U and 238U were ...

Investigation of the 240Pu(n, f ) reaction at the n_TOF/EAR2 facility in the 9 meV–6 MeV range
(American Physical Society, 2020)
Background: Nuclear waste management is considered amongst the major challenges in the field of nuclear energy. A possible means of addressing this issue is waste transmutation in advanced nuclear systems, whose operation ...

Towards PET range verification in proton therapy: new cross sections for improved accuracy
(2023-04-24)
Proton therapy is a form of radiotherapy that allows maximizing the deposited dose inside the tumour while reducing the dose in the healthy tissues, thanks to its superior depth-dose distribution when compared against ...

A segmented total energy detector (sTED) for (n, gamma) cross section measurements at n_TOF EAR2
(EPJ Web of Conf., 2023)
The neutron time-of-flight facility n_TOF is characterised by its high instantaneous neutron intensity, high resolution and broad neutron energy spectra, specially conceived for neutron-induced reaction cross section ...
