Abstract

Virgo is an experiment aiming at the detection of gravitational waves emitted by astrophysical sources. Its detector, based on a 3 km arms interferometer, is a complex setup which requires several digital control loops running up to 10 kHz, an accurate and reliable central timing system and an efficient data acquisition, all of them being distributed over 3 km. We overview here the main hardware and software components developed for the data acquisition system (DAQ) and its current architecture. Then, we briefly discuss its connections with interferometer's controls, especially through the automation of the interferometer's startup procedure. Then, we describe the tools used to monitor the DAQ and the performances we measured with them. Finally, are described also the tools developed for the online detector monitoring, mandatory complement of the DAQ for the commissioning of the virgo detector.

室女座引力波干涉探测器数据采集系统

处女座是一个旨在探测天体物理源发射的引力波的实验。它的探测器，基于一个3公里臂干涉仪，是一个复杂的设置，需要几个运行高达10千赫的数字控制回路，一个准确可靠的中央定时系统和一个有效的数据采集，所有这些都分布在3公里以上。本文概述了为数据采集系统(DAQ)开发的主要硬件和软件组件及其当前架构。然后，我们简要地讨论了它与干涉仪控制的联系，特别是通过干涉仪启动过程的自动化。然后，我们描述了用于监控DAQ的工具和我们用它们测量的性能。最后，还介绍了用于探测器在线监测的工具，这是处女座探测器调试时DAQ的强制补充。
