Construction and Assembly of the First Barrel Slice for the Electromagnetic Calorimeter of the PANDA Experiment — •Markus Moritz, Hans-Georg Zaunick, and Kai-Thomas Brinkmann for the PANDA collaboration — II. Pysikalisches Institut, Justus Liebig Universität, Gießen

The first major assembly stage of the barrel part of the electromagnetic calorimeter (EMC) of the PANDA experiment at the future FAIR facility will be presented. This consists in the construction of the first of 16 slices of the EMC barrel. The full EMC will be composed of two endcaps and a barrel, consisting of more than 11.300 tapered PbWO4 crystals. Each scintillator module is read out via two large area avalanche photo diodes connected to custom made ASIC-preamplifiers. The construction of the first segment comprises a full length slice beam holding in total 18 module blocks. Each block consists of a matrix of 4x10 crystals. The assembly procedure of single detector modules, module blocks and the overall slice segment, respectively, will be highlighted. Test results of single components and fully assembled detector modules will be discussed and compared with earlier prototype in-beam and lab tests.

Supported by BMBF, GSI and HIC for FAIR.
