爱因斯坦望远镜 (ET) 是欧洲第三代引力波探测器项目，其参考配置基于三角形，由三个臂长 10 公里的嵌套探测器组成，其中每个探测器都有一个“木琴”配置，由一个调谐到高频的干涉仪和一个调谐到低频并在低温下工作的干涉仪组成。在这里，我们研究了该参考设计的可能变化下的科学观点。我们对单个三角形几何天文台的科学案例进行了详细评估，并将其与位于欧洲的两个 L 形探测器（平行或未对准）网络获得的结果进行比较，考虑了三角形和 2L 几何形状的臂长的不同选择。我们还研究了在没有低频仪器的情况下，三角形和 2L 配置的科学输出如何变化。我们研究了一大类简单的“指标”，这些指标量化了与紧凑二元合并、多信使天文学和随机背景相关的科学产出，然后我们研究了不同探测器设计对一组更具体的科学目标的影响。
The Einstein Telescope (ET), the European project for a third-generation gravitational-wave detector, has a reference configuration based on a triangular shape consisting of three nested detectors with 10 km arms, where each detector has a 'xylophone' configuration made of an interferometer tuned toward high frequencies, and an interferometer tuned toward low frequencies and working at cryogenic temperature. Here, we examine the scientific perspectives under possible variations of this reference design. We perform a detailed evaluation of the science case for a single triangular geometry observatory, and we compare it with the results obtained for a network of two L-shaped detectors (either parallel or misaligned) located in Europe, considering different choices of arm-length for both the triangle and the 2L geometries. We also study how the science output changes in the absence of the low-frequency instrument, both for the triangle and the 2L configurations. We examine a broad class of simple 'metrics' that quantify the science output, related to compact binary coalescences, multi-messenger astronomy and stochastic backgrounds, and we then examine the impact of different detector designs on a more specific set of scientific objectives.
