Concepts for Pre-Assemply Data Acquisition for the PANDA Experiment* — •Milan Wagner, Thomas Geßler, Wolfgang Kühn, Sören Lange, and Björn Spruck for the PANDA collaboration — JLU Gießen

The PANDA detector will be a located at the high energy storage ring (HESR), at the facility for anti protons and ion research (FAIR) in Darmstadt, Germany. It will operate with a very high interaction rate of up to 20 MHz, in a free streaming mode without hardware trigger. Data filtering will be performed by complete online event recontruction with a highly parallelized farm of FPGAs as first level and on a farm fo GPUs or PCs as a second level. The requirement is a background reduction by a factor of >1000. Parts of the PANDA detector will be pre-assembled and tested at the Forschungszentrum Jülich, before being transported to GSI at a later stage. The data acquisition (DAQ) system for the pre-assembly comprises of a Synchronization Of Data Acquisition (SODA) source, up to 9 Trigger and Readout Boards (TRB) based on a Lattice ECP3 FPGAs, for data concentration, and up to 4 Compute Nodes (CN), for event building and filtering. A CN is a xTCA-compliant board based on a Virtex-5 FX70T FPGA, with a µTCA-formcator. It is equipped with 2x2 GB DDR2 RAM, one GB/Ethernet and 4x6.25 Gb/s optical links. In this contribution, we present the DAQ system for the pre-assembly for PANDA, which will have up to 207 optical links as inputs and Gb/Ethernet as output.
