New Perspectives for Neutron Capture Measurements in the Upgraded CERN-n_TOF Facility / J.Lerendegui-Marco, V.Furman, Y.Kopatch, [a.o.] // 15th International Conference on Nuclear Data for Science and Technology (ND2022), Held Virtually, July 21-29, 2022 [Electronic resource] / Ed.: C.M.Mattoon, R.Vogt, J.Escher, I.Thompson. – Les Ulis Cedex : EDP Sciences, 2023. – P.01028. – URL: https://doi.org/10.1051/epjconf/202328401028. – Bibliogr.:47.

The n_TOF facility has just undergone in 2021 a major upgrade with the installation of its third generation spallation target that has been designed to optimize the performance of the two n_TOF time-of-flight lines. This contribution describes the key features and limitations for capture measurements in the two beam lines prior to the target upgrade and presents first results of (n,γ) measurements carried out as part of the commissioning of the upgraded facility. In particular, the energy resolution, a key factor for both increasing the signal-to-background ratio and obtaining accurate resonance parameters, has been clearly improved for the 20 m long vertical beam-line with the new target design while keeping the remarkably high resolution of the long beamline n_TOF-EAR1. The improvements in the n_TOF neutron beam-lines need to be accompanied by improvements in the instrumentation. A review is given on recent detector R&D projects aimed at tackling the existing challenges and further improving the capabilities of this facility. – (EPJ Web of Conferences ; Vol.284) .
