Description
In particle physics and nuclear physics experiments, especially experiments based on particle accelerators, the data transmission rate of the detector is very high. These high throughput data from the front-end electronic of the detector need to be transmitted to the PC for the selection and summary of the event. Data acquisition (DAQ) systems with high density, scalability, and easy upgrading are essential to simplify the reading architecture of the entire experiment. A common data acquisition unit (CDAU) has been designed in a scalable DAQ system for particle physics and nuclear physics experiments at the High Intensity Heavy Ion Accelerator Facility (HIAF). The CDAU is a PCIe-based FPGA data acquisition readout unit. The same unit handles the data acquisition and distributes slow control to the detector's front-end electronics. The CDAU is based on a PCI Express (PCIe) Gen 2 × 8 interface and interfaces to eight optical links via a QSFP transceiver and four SFP+ transceivers for data collection, packaging, and transmission, using a Xilinx Kintex series FPGA as its central chip, combined with optical interfaces and peripheral circuitry. This paper presents the design of the CDAU, its performance, and its application test. As a result, it is proved that the CDAU can perfectly realize data transfer through the transmission link and accomplish data restoration. Thus, the system can meet the needs of HIAF experiments. We are now preparing joint tests with different multi-channel detectors in physics experiments. More experimental results will be presented in the meeting.
