Abstract
A data acquisition (DAQ) system for experiments with the Laser Electron Photons at SPring-8 (LEPS) has been developed based on the network distributed architecture. The system is designed so as to transfer digitized data with a 1-kHz trigger rate from various front-end electronics. Four local DAQ systems with VME board computers at the front end play a role to provide modularity, scalability, and flexibility. Data from each local DAQ system are sent through fast Ethernet to the data server. With this DAQ system, experiments to measure θ photo-productions at LEPS started on May 2000. Signals from scintillation counters, drift chambers, and silicon strip detectors were successfully stored on disk. The performance of the present DAQ system is found to be good enough for the measurement.
