A GEANT4 simulation of gamma clustering in CsI. — •Philipp Klenze1, Leyla Atar2, and Roman Gernhäuser1 for the R3B collaboration — 1Technische Universität München — 2Technische Universität Darmstadt
With over 1500 CsI(Tl) crystals, the CALIFA calorimeter is one of the cornerstones of the upcoming R3B experiment at the FAIR accelerator complex. One of its tasks will be the detection of gamma rays in the range from 100 keV to 30 MeV. Due to the high granularity of CALIFA, these energy deposit of gamma rays will generally be spread over multiple crystals. In this work a simplified geometry model in GEANT4 is used to study both the quantitative behavior of photons in CsI, cluster sizes and shapes, and energy and position reconstruction efficiency.
