Development of data acquisition system for gravitational wave using digital system

本研究采用100米引力波探测器CLIO原型机，建立了干涉仪控制、数据采集、诊断的基础技术，并采用具有实时操作系统的计算机。我们对引力波数据格式的定义、低延迟数据传输以及未来大型干涉仪的其他有用技术进行了展望。我们相信，当KAGRA， 3km干涉仪开始观测时，本研究的结果将直接用作直接探测引力波的技术。

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.
