论文摘要
最近提出了针对月球上的重力波（GW）探测器提出的新概念。这些包括激光触时检测器，该检测器作为自由范围或光纤干涉仪和惯性加速传感器提出。他们中的一些人利用月球对GWS的响应，另一些则遵循当前激光互动GW检测器的设计，该测试器直接用悬浮的光学元件直接测量重力应变。所有这些想法都出现了，因为与地球相比，月亮提供了极其安静的地球物理环境，但与此同时，也必须意识到，即使是安静的月球环境也对月球GW探测器的敏感性设定了限制。在本文中，我们将提出的任务概念从对GWS的反应角度进行比较，并评估它们如何受到月球地震背景的影响。我们讨论可用的缓解策略。从这些分析中，我们推断出每个检测器概念的主要观察带。
New concepts were recently proposed for gravitational-wave (GW) detectors on the Moon. These include laser-interferometric detectors, proposed as free-range or optical-fiber interferometers, and inertial acceleration sensors. Some of them exploit the response of the Moon to GWs, others follow the design of current laser-interferometric GW detectors, which directly measure the gravitational strain with suspended optics. All of these ideas emerged since the Moon offers an extremely quiet geophysical environment compared to Earth, but at the same time, one must realize that even the quiet lunar environment sets limits to the sensitivity of lunar GW detectors. In this article, we compare the proposed mission concepts in terms of their response to GWs and evaluate how they are affected by the lunar seismic background. We discuss available mitigation strategies. From these analyses, we infer the prime observation band of each detector concept.
