A new CVD Diamond Mosaic-Detector for (n,$\alpha$) Cross-Section Measurements at the n\_TOF Experiment at CERN

Abstract

At the n\_TOF experiment at CERN a dedicated single-crystal chemical vapor deposition (sCVD) Diamond Mosaic-Detector has been developed for (n,$\alpha$) 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 ${}^{59}$Ni(n,$\alpha$)${}^{56}$Fe reaction in 2012. The characteristics of the detector, its performance and the promising preliminary results of the experiment are presented.
