The system is composed of 6 front-end machine, one host machine and one event display server machine. All computer are PC-Linux. At the front-end machines, read out programs are written in C, data send to event builder at host machine, and data transfer program is written in JAVA language. On the host machine, the event builder is running and saving output to local DISK. These data are copied to the CCPS machine which writes them to tape. Another process transfers the output to event display server which is running on the event display machine.
