Abstract

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