This team is in charge of development and management of the common computer environment, Internet service, data acquisition system for experiments, and network environment at Nishina Center for Accelerator-based Science. In addition, we work for information security measures. We manage LINUX/UNIX NIS/NFS Cluster computer that can be used for calculations, data analysis of experimental data, web-page publication and e-mail service. For experiments at RIBF, we develop and operate a network distributed-type data acquisition (DAQ) system. To speed up DAQ performance, developments of parallel readout system and loss-less detector front-end system are in progress. Furthermore, an advanced DAQ scheme has been introduced using the time-stamping system and intelligent trigger system implemented with reconfigurable logic circuits. We are also working on international DAQ developments in collaboration with domestic and foreign researchers.
