摘要:

激光干涉引力波天文台(LIGO)的两台干涉仪最近探测到了来自双黑洞系统合并的引力波。这些探测器的输出的精确校准对于观测这些事件和提取源的参数至关重要。用于校准第二代(高级)LIGO探测器对引力波响应的主要工具是基于辐射压力的系统,称为光子校准器。这些系统是为Advanced LIGO完全重新设计的,包括几个重要的升级,使它们能够满足引力波天文学新时代第二代引力波探测器的校准要求。我们报告这些先进的LIGO光子校准器的设计,实施和操作,目前提供基准位移的顺序$10^{-18}$ m/ $\sqrt{\textrm{Hz}}$的准确度和精度优于1%。

英文摘要:

The two interferometers of the Laser Interferometry Gravitaional-wave Observatory (LIGO) recently detected gravitational waves from the mergers of binary black hole systems. Accurate calibration of the output of these detectors was crucial for the observation of these events, and the extraction of parameters of the sources. The principal tools used to calibrate the responses of the second-generation (Advanced) LIGO detectors to gravitational waves are systems based on radiation pressure and referred to as Photon Calibrators. These systems, which were completely redesigned for Advanced LIGO, include several significant upgrades that enable them to meet the calibration requirements of second-generation gravitational wave detectors in the new era of gravitational-wave astronomy. We report on the design, implementation, and operation of these Advanced LIGO Photon Calibrators that are currently providing fiducial displacements on the order of $10^{-18}$ m/$\sqrt{\textrm{Hz}}$ with accuracy and precision of better than 1 %.
