At the n_TOF experiment at CERN a dedicated single-crystal chemical vapor deposition (sCVD) Diamond Mosaic-Detector has been developed for (n,α) cross-section measurements. The detector, characterized by an excellent time and energy resolution, consists of an array of 9 sCVD diamond diodes. The detector has been characterized and a cross-section measurement has been performed for the 59Ni(n,α)56Fe reaction in 2012. The characteristics of the detector, its performance and the promising preliminary results of the experiment are presented.
•A large-area detector of 3 ×3 sCVD diamonds was built for (n, α) measurements.•The 59Ni(n, α)56Fe cross-section was measured successfully at n_TOF/CERN.•The energy resolution of the detector meets the expectations from simulations.•The reaction products during the measurement at n_TOF could clearly be separated.•The detector is suitable for (n, α) measurements in a heterogeneous beam.
