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 ...
Measurement of the 240Pu(n,f) cross-section at the CERN n-TOF facility : First results from experimental area II (EAR-2)
(EDP Sciences, 2017-09-13)
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 ...
Nuclear data activities at the n_TOF facility at CERN
(2016-10-21)
Nuclear data in general, and neutron-induced reaction cross sections in particular, are important for a wide variety of research fields. They play a key role in the safety and criticality assessment of nuclear technology, ...
Be 7 (n,α) He 4 Reaction and the Cosmological Lithium Problem : Measurement of the Cross Section in a Wide Energy Range at n-TOF at CERN
(2016-10-03)
The energy-dependent cross section of the Be7(n,α)He4 reaction, of interest for the so-called cosmological lithium problem in big bang nucleosynthesis, has been measured for the first time from 10 meV to 10 keV neutron ...
Recent results in nuclear astrophysics at the n-TOF facility at CERN
(2016-09-11)
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 new vertical neutron beam line at the CERN n-TOF facility design and outlook on the performance
(2015-11-01)
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 angular distribution of fission fragments using a PPAC assembly at CERN n-TOF
(2014-04-11)
A 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 ...
