Recent developments regarding the final PANDA Barrel EMC — •Aniko Tim Falk, Markus Moritz, Hans-Georg Zaunick, Kai-Thomas Brinkmann, Valera Dormenev, Kim Tabea Giebenhain, Christopher Hahn, Marvin Peter, Matthias Sachs, and René Schubert for the PANDA collaboration — II. Physikalisches Institut, Justus-Liebig-Universität, Gießen

The future electromagnetic calorimeter of the PANDA experiment will provide an excellent energy resolution over a wide dynamic range from a few dozens of MeV up to 15 GeV. The barrel part will consist of 16 segments. Each segment, with the exception of the two for the target pipe, includes 710 individual detectors. The main parts of each detector are a PWO-II crystal, two individual large area avalanche photo diodes and a preamplifier ASIC named APFEL (ASIC for Panda Front-end Electronics). In order to reveal the full potential of the calorimeter, even beyond the design goals, such aspects as the calibration, the APFEL settings and APD gains of each detector must be optimized to provide the best possible energy resolution.

In this talk the most recent progress concerning the final Barrel EMC design shall be presented.
