爱因斯坦望远镜的选址标准
Site-selection criteria for the Einstein Telescope
摘要:
爱因斯坦望远镜(Einstein Telescope,简称ET)是一个位于欧洲的下一代地下引力波探测器。相对于当前操作的检测器,它将提供大约一个数量级的灵敏度增加,并且此外,将观察频带向较低频率扩展,即,大约3Hz。首先需要作出的决定之一是关于未来的ET网站后,深入的网站特性。选址评估和选择是一个复杂的过程,要考虑到科学、财政、政治和社会经济标准。在本文中,我们提供了一个概述的ET的选址标准,提供了一个形式主义,以评估环境噪声对ET灵敏度的直接影响,并概述了必要的元素,一个网站的表征活动。
英文摘要:
The Einstein Telescope (ET) is a proposed next-generation, underground gravitational-wave (GW) detector to be based in Europe. It will provide about an order of magnitude sensitivity increase with respect to currently operating detectors, and furthermore, extend the observation band towards lower frequencies, i.e., down to about 3Hz. One of the first decisions that needs to be made is about the future ET site following an in-depth site characterization. Site evaluation and selection is a complicated process, which takes into account science, financial, political, and socio-economic criteria. In this paper, we provide an overview of the site-selection criteria for ET, provide a formalism to evaluate the direct impact of environmental noise on ET sensitivity, and outline the necessary elements of a site-characterization campaign.
