/n_TOF
The Am241(n,γ) cross section has been measured at the n_TOF facility at CERN with the n_TOF BaF2 Total Absorption Calorimeter in the energy range between 0.2 eV and 10 keV. Our results are analyzed as resolved resonances up to 700 eV, allowing a more detailed description of the cross section than in the current evaluations, which contain resolved resonances only up to 150–160 eV.

/n_TOF
Thin 33 S samples for the study of the 33 S(n, α ) 30 Si cross-section at the n_TOF facility at CERN were made by thermal evaporation of 33 S powder onto a dedicated substrate made of kapton covered with thin layers of copper, chromium and titanium. This method has provided for the first time bare sulfur samples a few centimeters in diameter. [...]

/n_TOF
The accuracy on neutron capture cross section of fissile isotopes must be improved for the design of future nuclear systems such as Gen-IV reactors and Accelerator Driven Systems. The High Priority Request List of the Nuclear Energy Agency, which lists the most important nuclear data requirements, includes also the neutron capture cross sections of fissile isotopes such as $^{233,235}$U and $^{239,241}$Pu.

The $^{236}$U isotope plays an important role in nuclear systems, both for future and currently operating ones. The actual knowledge of the capture reaction of this isotope is satisfactory in the thermal region, but it is considered insufficient for Fast Reactor and ADS applications. [...]

/n_TOF
New neutron cross section measurements of minor actinides have been performed recently in order to reduce the uncertainties in the evaluated data, which is important for the design of advanced nuclear reactors and, in particular, for determining their performance in the transmutation of nuclear waste. We have measured the $^{241} \text{Am(n}, \gamma)$ cross section at the n_TOF facility between 0.2 eV and 10 keV with a BaF$_2$ Total Absorption Calorimeter, and the analysis of the measurement has been recently concluded.

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 to preserve its unique data, facilitate access to them in standardised format, and allow their re-use by a wide community in the fields of nuclear physics, nuclear astrophysics and various nuclear technologies.

High precision measurement of the radiative capture cross section of $^{238}$U at the n_TOF CERN facility

Lodz (main)) ; Audouin, L (Orsay, IPN) ; Bécares, V (Madrid, CIEMAT) ; Barbagallo, M (INFN, Bari) ; Bečvář, F (Charles U., Prague (main)) ; Belloni, F (IRFU, Saclay) ; Berthoumieux, E (IRFU, Saclay) ; Billowes, J (U. Manchester (main)) et al.
/n_TOF
The importance of improving the accuracy on the capture cross-section of $^{238}$U has been addressed by the Nuclear Energy Agency, since its uncertainty significantly affects the uncertainties of key design parameters for both fast and thermal nuclear reactors. Within the 7th framework programme ANDES of the European Commission three different measurements have been carried out with the aim of providing the $^{238} \text{U(n,}\gamma)$ cross-section with an accuracy which varies from 1 to 5%, depending on the energy range.
