CALIFA detector test using the 208Pb(p,2p) reaction in direct kinematics — •Anna-Lena Hartig, Thorsten Kröll, Alexander Ignatov, Han-Bum Rhee, and Christian Sürder for the R3B collaboration — Institut für Kernphysik, TU Darmstadt, Germany

The 4π-calorimeter CALIFA is one of the major detectors of the R3B-experiment at the upcoming Facility for Antiproton and Ion Research (FAIR) in Darmstadt. CALIFA consists of 2464 CsI(Tl) crystals and 96 Phoswich detectors providing high efficiency, good energy resolution of 5 % for γ-rays at 662 keV and a large dynamic range, enabling a simultaneous measurement of γ-rays of E > 100 keV and light charged particles of up to E < 700 MeV. Besides the assembling of a CALIFA detector unit, this contribution will show first results of a test experiment with 192 CALIFA detectors at the Bronowice Cyclotron Center in November 2017 in Kraków where the 280Pb(p,2p) reaction was studied in direct kinematics with a proton beam of 200 MeV.

Supported by BMBF Project (05P15RDFN1,05P19RDFN1) and HIC for FAIR.
