Data Acquisition System of the NA64 Experiment

NA64 is a fixed-target experiment located at the H4 beam line of the Super Proton Synchrotron (SPS) at CERN. The experiment facility includes many different types of detectors. The Data Acquisition System is responsible for collecting the event data, for forming and propagating the trigger decision, and for time synchronization across different sub-systems. The DAQ hardware architecture is based on custom front-end electronics, data concentrators, buffering readout cards, server PCs and network equipment. All DAQ equipment is configured, managed and monitored by the RCCARS software package, which is also responsible for reading the experimental data and writing them to a data storage.
