Due to the fact that it is planned to have a functional pre-assembling of the PANDA detector at the Research centre Jülich, 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 shelf we are using is the "MicroTCA.0 System, Cube, 3 HE, 30 TE, für 4 Single Full-size-AdvancedMC-Module".
  • File "63972-272.pdf" is the user's manual of the MicroTCA.0 System, Cube.

We use as a shelf controller the Kontron AM4901 a precise description can be found in:
  • File "1022-5813_10_SK-MAN-AM4901.pdf"
  • File "1035-8760_30_SK-MAN-AM5901-IPMI-FW-UG.pdf"


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