Simulations and Measurements of Response of LaBr3(Ce) and CeBr3 — •Han-Bum Rhee, Guillermo Fernández Martínez, Anna-Lena Hartig, Ilja Homm, Alexander Ignatov, and Thorsten Kröll for the R3B collaboration — Institut für Kernphysik, TU Darmstadt, Germany
CALIFA is a calorimeter and spectrometer that aims to detect gamma-rays and light charged particles.
It is a part of the R3B experiment at the future FAIR facility. CALIFA consists of the Barrel covering central angles and the EndCap covering forward angles.
We investigated novel scintillation materials (LaBr3(Ce) and CeBr3) as an alternative solution for the EndCap.
Scintillators were tested with proton-beam and gamma-rays at different energy ranges. In addition, we have simulated the response of the scintillation detector using the GEANT4 toolkit to understand the measured signals.
In this presentation, we show the experimental data and compare them with the simulation results.
