The Nuclear Astrophysics program at n-TOF (CERN)
(EDP Sciences, 2017-12-30)
An important experimental program on Nuclear Astrophysics is being carried out at the n-TOF since several years, in order to address the still open issues in stellar and primordial nucleosynthesis. Several neutron capture ...
High-accuracy determination of the neutron flux in the new experimental area n_TOF-EAR2 at CERN
(2017-10-27)
A new high flux experimental area has recently become operational at the n_TOF facility at CERN. This new measuring station, n_TOF-EAR2, is placed at the end of a vertical beam line at a distance of approximately 20m from ...
The measurement programme at the neutron time-of-flight facility n-TOF at CERN
(EDP Sciences, 2017-09-13)
Neutron-induced reaction cross sections are important for a wide variety of research fields ranging from the study of nuclear level densities, nucleosynthesis to applications of nuclear technology like design, and criticality ...
Monte carlo simulations of the n-TOF lead spallation target with the Geant4 toolkit : A benchmark study
(EDP Sciences, 2017-09-13)
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 ...
High accuracy 234U(n,f) cross section in the resonance energy region
(EDP Sciences, 2017-09-13)
New results are presented of the 234U neutron-induced fission cross section, obtained with high accuracy in the resonance region by means of two methods using the 235U(n,f) as reference. The recent evaluation of the 235U(n,f) ...
The n-TOF facility : Neutron beams for challenging future measurements at CERN
(EDP Sciences, 2017-09-13)
The CERN n-TOF neutron beam facility is characterized by a very high instantaneous neutron flux, excellent TOF resolution at the 185 m long flight path (EAR-1), low intrinsic background and coverage of a wide range of ...
Characterization of the n-TOF EAR-2 neutron beam
(EDP Sciences, 2017-09-13)
The experimental area 2 (EAR-2) at CERNs neutron time-of-flight facility (n-TOF), which is operational since 2014, is designed and built as a short-distance complement to the experimental area 1 (EAR-1). The Parallel Plate ...
Time-of-flight and activation experiments on 147Pm and 171Tm for astrophysics
(EDP Sciences, 2017-09-13)
The neutron capture cross section of several key unstable isotopes acting as branching points in the s-process are crucial for stellar nucleosynthesis studies, but they are very challenging to measure due to the difficult ...
Dissemination of data measured at the CERN n-TOF facility
(EDP Sciences, 2017-09-13)
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 ...
