论文摘要

月球重力 - 波天线是月球表面上提出的低频引力波检测器。它将由一系列高端低温超导惯性传感器(CSISS)组成。低温环境将与超导材料结合使用,以打开通往低损坏的执行器和传感器力学的途径。 CSIS在0.5 Hz的0.5 Hz的3个数量级比当前的最新时间更好的位移敏感性彻底改变了(低温)惯性传感器场。它将使月球重力波天线对1 Hz低于1 Hz,低至1 MHz敏感,并且它也将用于即将到来的Einstein望远镜(第三代重力波检测器)中,它将利用低温技术,并且将具有更高的敏感性低于10 Hz。此外,还可以使用CSIS地震数据来获得有关月球内部以及我们所谓的Selene-Physics的新见解。

The Lunar Gravitational--Wave Antenna is a proposed low-frequency gravitational-wave detector on the Moon surface. It will be composed of an array of high-end cryogenic superconducting inertial sensors (CSISs). A cryogenic environment will be used in combination with superconducting materials to open up pathways to low-loss actuators and sensor mechanics. CSIS revolutionizes the (cryogenic) inertial sensor field with a modelled displacement sensitivity at 0.5 Hz of 3 orders of magnitude better than the current state-of-the-art. It will allow the Lunar Gravitational-Wave Antenna to be sensitive below 1 Hz, down to 1 mHz and it will also be employed in the forthcoming Einstein Telescope --a third-generation gravitational-wave detector which will make use of cryogenic technologies and that will have an enhanced sensitivity below 10 Hz. Moreover, CSIS seismic data could also be employed to obtain new insights about the Moon interior and what we can call the Selene-physics.
