FPGA - Based Compute Nodes for the PANDA Experiment at FAIR

Wolfgang Kühn Camilla Gilardi D. Kirschner Johannes Lang J. S. Lange

PANDA is a new universal detector for antiproton physics at the HESR facility at FAIR/GSI. The PANDA data acquisition system has to handle interaction rates of the order of 10 ^** 7 /s and data rates of several 100 Gb /s. FPGA based compute nodes with multi-Gbit/s bandwidth capability using the ATCA architecture are designed to handle tasks such as event building, feature extraction and high level trigger processing. Each board is equipped with 5 Virtex4 FX60 FPGAs. High bandwidth connectivity is provided by four Gbit Ethernet links and 8 additional optical links connected to RocketIO ports. A single ATCA crate can host up to 14 boards which are interconnected via a full mesh backplane.

FPGA based high speed data transmission with optical fiber in trigger system of BESIII

IEEE conference record/IEEE conference record - Nuclear Science Symposium & Medical Imaging Conference. (2007)

X. Q. Hao Zhan'an Liu Yunpeng Lu Lu Li Zhao Dixin

The article described a new design of high-speed data transmission, used in BESIII trigger system, with optical fibre that was based on the on-chip serial/deserial transceiver in FPGA. A special custom protocol is defined to transfer the consecutive and real-time data, recover and process the data belongs to the same event at the same time. The design was tested for a long period run. A high level of confidence bit error rate was obtained, and all channels from different transmitters were re-aligned by using unfixed delay alignment method. The design was implemented in the trigger system and would meet the requirements of BESIII.

The trigger system for the drift chamber of BESIII

IEEE Nuclear Science Symposium conference record (2008)

X. Q. Hao Lu Li Yunpeng Lu Zhi Liu Shujun Wei

This paper describe the scheme design and hardware implementation of trigger system for drift chamber of BESIII, the key part of the trigger system of BESIII. The selection of trigger conditions and the capability of trigger efficiency and background rejection were studied carefully by simulation. Optical link was designed between the FEE and the trigger processor for complete electrical isolation avoiding ground loops and common mode problems. On-chip serial/deserial transceiver embedded in FPGA was used to enhance integration and stability. The long-term data taking had proved the operation stability and reliability of the system, demonstrated the good operation performance of each subsystem and the good integrated performance of the whole system, and fulfilled the request of BESIII.
