Overview of CALIFA in FAIR-Phase-0 Experiments at R3B — •Leyla Atar1, Christian Sürder1, Thorsten Kröll1, Roman Gernhäuser2, and Philipp Klenze2 for the R3B collaboration — 1Institut für Kernphysik, Technische Universität Darmstadt, Germany — 2Technische Universität München, Germany
CALIFA (the CALorimeter for In Flight detection of γ-rays and light charged pArticles) is one of the key detectors of the R3B experiment at the GSI/FAIR facility. CALIFA is highly segmented and currently consists of 1528 scintillation CsI(Tl) crystals surrounding the reaction target area to facilitate measurement of the emission angle and energy of reaction products. CALIFA covers a large dynamic range to allow a simultaneous measurement of γ-rays down to 100 keV and scattered protons up to 300 MeV. A special feature of CALIFA is the digital Quick Particle Identification (QPID) enabling γ-rays and charged particle identification through Pulse Shape Analysis (PSA) of the scintillation light output.
I will shortly introduce the CALIFA calorimeter and its auxiliary detector systems and give an overview of the performance of CALIFA in the frame of FAIR-Phase-0 experiments performed at the R3B/FAIR setup. First results from specific reaction channels will be presented.
