Digital signal processing applied to fast scintillators response — •Guillermo Fernández Martínez, Anna-Lena Hartig, Ilja Homm, Alexander Ignatov, Thorsten Kröll, and Han-Bum Rhee for the R3B collaboration — Institut für Kernphysik, TU Darmstadt, Germany
The future Facility for Antiproton and Ion Research (FAIR) will house the calorimeter
and spectrometer CALIFA, whose design, construction and testing are currently being
carried out by the R3B collaboration. CALIFA is an array of scintillation
crystals arranged in a barrel configuration, which covers a large solid angle.
Some of the scintillation materials under consideration (LaBr3(Ce), LaCl3(Ce) and CeBr3) have been
developed in the last few years. Their main characteristic is a combination of good energy and time resolution with high efficiency.
On the other hand, fast digitisers allow the collection of data at increasingly higher sampling frequencies. They are also much more reliable and easily scalable for large arrays
than traditional analog electronics. Our research takes advantage of these features and
is therefore focused on the analysis of digitised pulses, which, in addition to energy and time determination, enables particle identification. In this contribution we present results obtained
in different campaigns.
