A segmented total energy detector (sTED) for (n, γ) cross section measurements at n_TOF EAR2 / n_TOF Collaboration
The neutron time-of-flight facility n_TOF is characterised by its high instantaneous neutron intensity, high-resolution and broad neutron energy spectra, specially conceived for neutron-induced reaction cross section measurements. Two Time-Of-Flight (TOF) experimental areas are available at the facility: experimental area 1 (EAR1), located at the end of the 185 m horizontal flight path from the spallation target, and experimental area 2 (EAR2), placed at 20 m from the target in the vertical direction.

Neutron capture and total cross-section measurements on $^{94,95,96}$Mo at n_TOF and GELINA / n_TOF Collaboration
Capture and total cross section measurements for 94,95,96Mo have been performed at the neutron time-of-flight facilities, n_TOF at CERN and GELINA at JRC-Geel. The measurements were performed using isotopically enriched samples with an enrichment above 95% for each of the 94,95,96Mo isotopes. [...]

Multi-section fission ionization chamber for measurement of 239Pu(n,γ) reaction in fission tagging method / Perkowski, J (Lodz U.) ; Alcayne, V (Madrid, CIEMAT) ; Andrzejewski, J (Lodz U.) ; Cano-Ott, D (Madrid, CIEMAT) ; Gawlik-Ramięga, A (Lodz U.) ; Mendoza, E (Madrid, CIEMAT) ; Sánchez-Caballero, A (Madrid, CIEMAT) ; Sibbens, G (Geel, JRC) ; Vanleeuw, D (Geel, JRC) ; Aberle, O (CERN) et al.
The 239Pu(n,γ) reaction cross section is very important for operation of both thermal and fast reactors, when loaded with MOX fuels. According to the NEA/OECD High Priority Request List the precision of cross section data for this reaction should be improved. [...]

The measurement of the $^{235}$U(n,f) reaction cross section in the neutron energy region 10 MeV to 500 MeV was carried out at the CERN n_TOF facility. The experimental campaign, completed in 2018, provided precise and accurate data on the fission reaction relative to neutron-proton elastic scattering. [...]

The neutron time-of-flight facility n_TOF at CERN Recent facility upgrades and detector developments / n_TOF Collaboration
Based on an idea by Carlo Rubbia, the n_TOF facility at CERN has been operating for over 20 years. It is a neutron spallation source, driven by the 20 GeV/c proton beam from the CERN PS accelerator. [...]

Measurement of the $^{244}Cm$ and $^{246}Cm$ neutron-induced capture cross sections at the n_TOF facility / Alcayne, V (Madrid, CIEMAT) ; Kimura, A (JAERI, Tokai) ; Mendoza, E (Madrid, CIEMAT) ; Cano-Ott, D (Madrid, CIEMAT) ; Martínez, T (Madrid, CIEMAT) ; Aberle, O (CERN) ; Andrzejewski, J (Lodz U.) ; Audouin, L (Orsay, IPN) ; Bécares, V (Madrid, CIEMAT) ; Bacak, M (CERN ; IRFU, Saclay ; Vienna, Tech. U.) et al.
The neutron capture reactions of the $^{244}$Cm and $^{246}$Cm isotopes open the path for the formation of heavier Cm isotopes and heavier elements such as Bk and Cf in a nuclear reactor. In addition, both isotopes belong to the minor actinides with a large contribution to the decay heat and to the neutron emission in irradiated fuels. [...]

High-resolution cross section measurements for neutron interactions on $^{89}$Y with incident neutron energies up to 95 keV / Tagliente, G (INFN, Bari) ; Milazzo, P M (INFN, Trieste) ; Paradela, C (Geel, JRC) ; Kopecky, S (Geel, JRC) ; Vescovi, D (INFN, Perugia ; Cagliari Observ.) ; Alaerts, G (Geel, JRC) ; Damone, L A (INFN, Bari ; CERN) ; Heyse, J (Geel, JRC) ; Krtička, M (Charles U.) ; Schillebeeckx, P (Geel, JRC) et al.
The cross section of the $^{89}$Y(n, $\gamma $) reaction has important implications in nuclear astrophysics and for advanced nuclear technology. Given its neutron magic number N = 50 and a consequent small neutron capture cross section, $^{89}$Y represents one of the key nuclides for the stellar s-process. [...]

Measurement of the Ce140(n,γ) Cross Section at n_TOF and Its Astrophysical Implications for the Chemical Evolution of the Universe / n_TOF Collaboration
Ce140(n,γ) is a key reaction for slow neutron-capture (s-process) nucleosynthesis due to being a bottleneck in the reaction flow. For this reason, it was measured with high accuracy (uncertainty ≈5%) at the n_TOF facility, with an unprecedented combination of a high purity sample and low neutron-sensitivity detectors. [...]
