Digital signal processing applied to fast timing measurements with scintillating detectors — •Guillermo Fernández Martínez, Alexander Ignatov, Stoyanka Ilieva, and Thorsten Kröll — Institut für Kernphysik, Technische Universität Darmstadt, Schlossgartenstr. 9, 64289 Darmstadt
In the last few years, new scintillation materials (like LaBr3(Ce) and CeBr3) have been proved to be very appropriate detectors for fast timing measurements, due to their combination of good energy and time resolution with high efficiency. At the same time, the emergence of fast digitisers, that allow for the collection of data at increasingly higher sampling frequencies and are easily scalable to large arrays, such as FATIMA@FAIR, has favoured the transition from traditional, analogue time pick-off methods towards pure digital ones. In our work, we present the results of time resolution measurements with standard radioactive sources, with new, purely digital methods through pulse shape analysis.
