摘要

在前几次观测运行期间进行了初步测试之后，开发了牛顿校准器（NCal）系统，并安装在室女座引力波探测器上，用于 O4 观测运行。该系统持续运行，为本次运行提供室女座绝对校准。其注入信号振幅的不确定性为 0.17%，优于光子校准器（PCal）等其他校准技术。本文介绍了这一 NCal 系统，并详细说明了不确定性的不同来源。

The Virgo Newtonian calibration system for the O4 observing run

After initial tests performed during previous observing runs, a Newtonian calibrator (NCal) system was developed and installed on the Virgo gravitational wave detector for the O4 observing run. This system, which is continuously operated, provides the absolute calibration of Virgo for this run. Its uncertainty of 0.17% on the amplitudes of the injected signals is better than that obtained with other calibration techniques like the photon calibrator (PCal). This paper presents this NCal system and details the different sources of uncertainties.
