Development of data acquisition system for gravitational wave using digital system

This study used a 100 meter prototype gravitational wave detector called CLIO, and established basic technologies for control, data acquisition, diagnostic of interferometers using computers with real time operating system. We obtained some prospects for a definition of gravitational wave data format, low latency data transfer, and other useful techniques for future large scale interferometers. We believe that results of this study will be directly used as technologies for a direct detection of gravitational wave when the observation starts by the KAGRA, 3km interferometer.
