Due to the fact that it is planned to have a functional pre-assembling of the PANDA detector at the Research centre J├╝lich, a prototype DAQ related to the PANDA DAQ has to be built. It will be a DAQ system with similar components and similar functionality as the final DAQ, but less requirement according to lower data rates in the pre-assembling phase. The pre-assembly DAQ will be realised in a three step process. As a first step the prototype trigger-less data acquisition (PTDAQ), a small but scalable start version, is prepared. It will be used for testing sub-detector prototype. Using the same online reconstruction algorithms as the PANDA DAQ, it will provide a full online event building. For testing reasons a SODANET emulator has be prepared. The second step will be an extended version including the CN. This allows a better interconnection between the xFP cards, and higher data rate handling. Starting with one CN, this version can than be expanded to the final pre-assembly DAQ.


The document ptdaq.jpg is a schematic of the prototype trigger-less DAQ.
