The Prototype Triggerless Data Aquisition of the PANDA Experiment — •Milan Wagner, Simon Reiter, Sören Lange, and Wolfgang Kühn for the PANDA collaboration — II. Physikalisches Institut

The PANDA detector 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 reconstruction with a highly parallelized farm of FPGAs as first level and on a farm of GPUs or PCs as a second level. The requirement is a back- ground reduction by a factor of >1000. A prototype trigger-less data acquisition (PTDAQ) system for the detector validation measurements comprises free streaming and synchronization readout, for event building and filtering has been developed. A first in beam environment test was performed at the Mainzer Mikrotron, reading out the barrel electromagnetic calorimeter prototype (Proto120). *This work is supported by BMBF(05P12RGFPF), HGS-HIRe for FAIR and the LOEWE-Zentrum HIGforFAIR.
