论文摘要
在2021年春季，安装了处女座干涉仪的输入模式清洁剂围绕悬浮端镜的新型仪器挡板。此后，该设备在实验中定期操作，并且获得的结果表明，该设备与光学腔内杂散光的模拟达成了良好的一致性。挡板将在即将到来的O4观察跑中运行，并作为该技术的演示器，旨在在O5及时及时在主镜前挡板。在本文中，我们介绍了挡板设计的详细说明，包括力学，前端电子，数据采集以及光学和真空测试，校准和安装程序以及性能结果。
A novel instrumented baffle surrounding the suspended end mirror in the input mode cleaner cavity of the Virgo interferometer was installed in spring 2021. Since then, the device has been regularly operated in the experiment and the obtained results indicate a good agreement with simulations of the stray light inside the optical cavity. The baffle will operate in the upcoming O4 observation run, serving as a demonstrator of the technology designed to instrument the baffles in front of the main mirrors in time for O5. In this paper we present a detailed description of the baffle design, including mechanics, front-end electronics, data acquisition, as well as optical and vacuum tests, calibration and installation procedures, and performance results.
