Characterisation of a Prototype for the Backward End-Cap of the PANDA EMC. — Heybat Ahmadi1,2, Samer Ahmed1, Luigi Capozza1,3, Alaa Dbeyssi1,3, •Malte Deiseroth1,2, Bertold Fröhlich1,3, Dmitry Khaneft1,2, Dexu Lin1,3, Frank Maas1,3, María Carmen Mora Espí1,3, Cristina Morales Morales1,3, Oliver Noll1,2, David Rodríguez Piñeiro1,3, Roserio Valente1,2, Manuel Zambrana1,2, and Iris Zimmermann1,3 for the PANDA collaboration — 1HIM — 2UNI-MAINZ — 3GSI
The PANDA detector at FAIR will be used to study interactions of antiprotons in a fixed target experiment. The electromagnetic calorimeter (EMC) of the target spectrometer, consisting of > 15,000 PWO crystals, with its expected excellent performance and efficiency, will be one of the central components to achieve the physical goals. A first prototype for the Backward End-Capt (BWC) containing 16 crystals has been build and tested during 3 days of beamtime. The test was done with tagged photons in an energy range from about 50 MeV to 700 MeV at the Mainzer Microtron (MAMI). The prototype was desinged to be as close as possible to the final desing of the BWC. This talk will give a short introduction in the design of the prototype and the latest updates, followed by a presentation of the results from the beam time. It will describe the data analysis and the extraction of the energy resolution.
