First results of the140ce(N,ү)141ce cross-section measurement at n_tof
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
An accurate measurement of the140Ce(n,ү) energy-dependent cross-section was performed at the n_TOF facility at CERN. This cross-section is of great importance because it represents a bottleneck for the s-process nucleosynthesis ...

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 ...

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 ...

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 ...
