Abstract: 
Current and future nuclear technologies require more accurate nuclear data on (n,γ) cross sections and the α-ratios of fissile isotopes. Their measurement presents several difficulties, mainly related to the strong fission γ-ray background competing with the weaker γ-ray cascades used as the experimental signature of the (n,γ) process. A specific setup was used at the CERN n_TOF facility in 2012 for the measurement of the (n,γ) cross section and α-ratios of fissile isotopes and used for the case of the ²³⁵U isotope. The setup consists of a set of micromegas fission detectors surrounding the ²³⁵U samples all placed inside a segmented BaF₂ Total Absorption Calorimeter.
