摘要
爱因斯坦望远镜（ET）是欧洲的第三代引力波探测器项目，其参考配置基于三角形形状，由三个臂长10 km的嵌套探测器组成，其中每个臂包含一种“ xylophone”配置，由一个调谐至高频的干涉仪和一个调谐至低频并以低温工作的干涉仪构成。在此，我们考察该参考设计在可能变动下的科学前景。我们详细评估了单一三角形几何观测台的科学案例，并将其与位于欧洲的两个L形探测器（平行或错位）网络所得结果进行比较，考虑了三角形和2L几何下不同的臂长选择。我们还研究了在无低频仪器时（对三角形和2L配置均如此）科学产出如何变化。我们考察了与致密双星并合、多信使天文学和随机背景相关、量化科学产出的广泛简单“度量”类指标，进而考察不同探测器设计对一组更具体科学目标的影响。
