Monte carlo simulations of the n-TOF lead spallation target with the Geant4 toolkit: A benchmark study
(EDP Sciences, 2017)
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 ...

A new CVD Diamond Mosaic-Detector for (n, α ) Cross-Section Measurements at the n TOF Experiment at CERN
(Elsevier, 2013)
At the n\_TOF experiment at CERN a dedicated single-crystal chemical vapor deposition (sCVD) Diamond Mosaic-Detector has been developed for (n,alpha) cross-section measurements. The detector, characterized by an excellent ...

Fission Fragment Angular Distribution measurements of 235U and 238U at CERN n-TOF facility
(EDP Sciences, 2016)
Neutron-induced fission cross sections of 238U and 235U are used as standards in the fast neutron region up to 200 MeV. A high accuracy of the standards is relevant to experimentally determine other neutron reaction cross ...

Preparation and characterization of 33-S samples for 33-S(n,alpha)30-Si cross-section measurements at the n_TOF facility at CERN
(Elsevier, 2018-02-15)
Thin 33S samples for the study of the 33S(n,a)30Si cross-section at the n_TOF facility at CERN were made by thermal evaporation of 33S powder onto a dedicated substrate made of kapton covered with thin layers of copper, ...

Angular distribution in the neutron-induced fission of actinides
(EDP Sciences, 2013)
Above 1 MeV of incident neutron energy the fission fragment angular distribution (FFAD) has generally a strong anisotropic behavior due to the combination of the incident orbital momentum and the intrinsic spin of the ...

Silicon-based three-dimensional microstructures for radiation dosimetry in hadrontherapy
(AIP Publishing, 2015)
In this work, we propose a solid-state-detector for use in radiation microdosimetry. This device improves the performance of existing dosimeters using customized 3D-cylindrical microstructures etched inside silicon. The ...

The new vertical neutron beam line at the CERN n_TOF facility design and outlook on the performance
(Elsevier, 2015)
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 ...

High accuracy 234U(n,f) cross section in the resonance energy region
(EDP Sciences, 2017)
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 ...
