New insights on fission of $^{235}$U induced by high energy neutrons
/ n_TOF Collaboration
The $^{235}$U(n,f) reaction cross section was measured relative to neutron-proton elastic scattering for the first time in the energy region from 10 MeV to 440 MeV at the CERN n_TOF facility, extending the upper limit of the only previous measurement in the literature by more than 200 MeV. Two independent detection systems were used simultaneously to extract the fission cross section. [...]

/n_TOF
The experimental area 2 (EAR-2) at CERNs neutron time-of-flight facility (n_TOF), which is operational since 2014, is designed and built as a short-distance complement to the experimental area 1 (EAR-1). The Parallel Plate Avalanche Counter (PPAC) monitor experiment was performed to characterize the beam profile and the shape of the neutron flux at EAR-2. [...]

/n_TOF
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.

Validation of Cross Sections with Criticality Experiment and Reaction Rates: the Neptunium Case
/ Leong, L S (Orsay, IPN) ; Tassan-Got, L (Orsay, IPN) ; Audouin, L (Orsay, IPN) ; Berthier, B (Orsay, IPN) ; Le Naour, C (Orsay, IPN) ; Stéphan, C (Orsay, IPN) ; Paradela, C (Santiago de Compostela U.) ; Tarrío, D (Santiago de Compostela U.) ; Duran, I (Santiago de Compostela U.)
The Np-237 neutron-induced fission cross section has been recently measured in a large energy range (from eV to GeV) at the n\_TOF facility at CERN. When compared to previous measurements the n\_TOF fission cross section appears to be higher by 5-7\% beyond the fission threshold. [...]

Study of 234U(n,f) Resonances Measured at the CERN n_TOF Facility
/ Leal-Cidoncha, E (U. Santiago de Compostela (main)) ; Durán, I (U. Santiago de Compostela (main)) ; Paradela, C (U. Santiago de Compostela (main)) ; Tarrío, D (U.

We present the analysis of the resolved resonance region for the U-234(n,f) cross section data measured at the CERN n\_TOF facility. The resonance parameters in the energy range from 1 eV to 1500 eV have been obtained with the SAMMY code by using as initial parameters for the fit the resonance parameters of the JENDL-3.3 evaluation.
