Test of a PCIe based readout option for PANDA — •Simon Reiter1, Heiko Engel2, Sören Lange1, and Wolfgang Kühn1 for the PANDA collaboration — 1Justus-Liebig-Universität Giessen, Germany — 2Goethe-Universität Frankfurt, Germany
The future PANDA detector will achieve an event rate at about 20 MHz resulting in a high data load of up to 200 GB/s. The data acqui- sition system will be based on a triggerless readout concept, leading to the requirement of large data bandwidths. The data reduction will be guaranteed on the rst level by an array of FPGAs running a full on- line reconstruction followed by the second level of a CPU/GPU cluster to achieve a reduction factor more than 1000.
The C-RORC (Common Readout Receiver Card), originally devel- oped for ALICE (A. Borga et al., JINST 10 (2015) 02, C02022), pro- vides on the one hand 12 optical links with 6.25 Gbps each, and on the other hand a PCIe interface with up to 40 Gbps.
The receiver card has been installed and tested, and the rmware has been adjusted for the Panda data format. Test results will be presented. *This work is supported by BMBF(05P12RGFPF).
