Research facilities and highlights at the Centro Nacional de Aceleradores (CNA)
(Springer, 2021)
The Centro Nacional de Aceleradores is a user-oriented accelerator facility in Seville, Spain. Its main facilities are a 3 MV tandem accelerator, an 18 MeV proton Cyclotron, a tandetron used for AMS, a compact accelerator ...

New measurement of the 242Pu(n,γ) cross section at n_TOF
(EDP Sciences, 2016)
The use of MOX fuel (mixed-oxide fuel made of UO2 and PuO2) in nuclear reactors allows substituting a large fraction of the enriched Uranium by Plutonium reprocessed from spent fuel. With the use of such new fuel composition ...

Thermal (n, γ) cross section and resonance integral of 171Tm
(American Physical Society, 2019)
Background: About 50% of the heavy elements are produced in stars during the slow neutron capture process. The analysis of branching points allows us to set constraints on the temperature and the neutron density in ...

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)
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 ...

Measurement of 208 Pb ( n , γ ) 209 Pb Maxwellian averaged neutron capture cross section
(American Physical Society, 2017)
The doubly magic 208Pb nucleus is a bottleneck at the termination of the s-process path due to its very low neutron capture cross section. This cross section is also important for the decomposition ofs,r processes and ...

Simultaneous measurement of neutron-induced capture and fission reactions at CERN
(Springer Verlag, 2012)
The measurement of the capture cross-section of fissile elements, of utmost importance for the design of innovative nuclear reactors and the management of nuclear waste, faces particular difficulties related to the γ-ray ...

Production yields of beta+ emitters for range verification in proton therapy
(EDP Sciences, 2020)
In-vivo Positron Emission Tomography (PET) range verification relies on the comparison of the measured and estimated activity distributions from β+ emitters induced by the proton beam on the most abundant elements in the ...

A compact fission detector for fission-tagging neutron capture experiments with radioactive fissile isotopes
(Elsevier, 2020)
In the measurement of neutron capture cross-sections of fissile isotopes, the fission channel is a source of background which can be removed efficiently using the so-called fission-tagging or fission-veto technique. For ...

Measuring neutron capture rates on ILL-produced unstable isotopes (147Pm, 171Tm and 204Tl, and plans for 79Se and 163Ho) for nucleosynthesis studies
(EDP Sciences, 2018)
Neutron capture cross sections are among the main inputs for nucleosynthesis network calculations. Although well known for the majority of the stable isotopes, this quantity is still unknown for most of the unstable isotopes ...

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 ...
