Status of the CALIFA Calorimeter and its performance at FAIR-Phase-0 experiments at R3B — •Leyla Atar for the R3B collaboration — Technische Universität Darmstadt, 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 will consist of 2528 scintillation CsI(Tl) crystals after completion surrounding the reaction target area to facilitate measurement of the emission angle and energy of reaction products. CALIFA covers a huge dynamic range to allow a simultaneous measurement of γ-rays down to 100 keV and scattered light particles 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. Particularly first results, energy resolution and efficiency as well as QPID will be discussed for specific physics cases. The current development status of CALIFA and further enhancements will be presented.
