Description
Improvement on nuclear data has received a special attention in the last decades within the framework of “Technology Advances in Fast Reactors and Accelerator Driven System for Actinides and Long-Lived Fission Products Transmutation”. Neutron cross section (capture, fission, inelastic) data for minor actinides (MA), as well as delayed neutron data and decay heat data with improved accuracy have been requested within the WEPC (NEA-OECD) recommendations [1].
The improvement of the neutron detection systems and techniques contributes greatly to reduce the uncertainties in the nuclear data. Neutron spectroscopy by time-of-flight has been pointed out as one of the techniques to provide improved results in delayed neutron emission measurements. Such a technique can benefit from developments on digital signal processing techniques as well as from the use of appropriate scintillation material.
The characterization of the detectors in terms of time and energy resolution, light collection, detection threshold and n/g discrimination as well as the measurement of the response function at known irradiation fields is mandatory for the proper design of the spectrometer. The use of a digital DAQ system, based on digitizer will allow evaluating the performance of the digital signal techniques. A review of the design status of spectrometer and some preliminary results from the characterization measurements performed in lab and at the PIAF facility in PTB (Braunschweig) [2] will be presented in this work.
