This awards supports research in gravitational wave detector instrumentation, and it addresses the priority areas of NSF's "Windows on the Universe" Big Idea. Since its initial gravitational-wave discovery in 2015 the NSF's Advanced LIGO has observed numerous black hole and neutron star collisions, shedding new light on a broad set of questions in astrophysics, cosmology, fundamental physics, and nuclear physics. The observatories' sensitivity can be improved further by controlling thermal distortion effects when operating at high laser power, and by lowering the thermal noise in its test mass mirror coatings. This award funds research into better laser wave front distortion sensors and actuators, and supports collaborative research into finding better coating materials for terrestrial gravitational-wave detectors. Both research directions pursue the common goal of significantly expanding the observational reach of Advanced LIGO. The award provides students and postdocs access to a world-class observatory and prepares them for scientific leadership positions.The award specifically provides funding for: (i.) The development mode-converter-based optical wave front sensors, capable of simultaneously sensing cavity alignment and mode-match for the Advanced LIGO detector. (ii.) The development of a phase camera, based on pixel-demodulation, to provide high-resolution RF beat maps of the laser field in the detector at a high frame rate. The camera is intended for use in interferometer commissioning and feedback control. (iii.) Exploring options for sensing and control of higher-order wave front aberrations. (iv.) Continued commissioning support in collaboration with LIGO Laboratory to improve the astrophysical sensitivity and bandwidth of Advanced LIGO in the upcoming O3 and O4 observing runs. (v.) Installation support for the construction and testing of a cryogenic nodal suspension for measuring mechanical loss of new coatings down to cryogenic temperatures.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项支持引力波探测器仪器的研究，并解决了美国国家科学基金会“宇宙之窗”重大构想的优先领域。自2015年首次发现引力波以来，美国国家科学基金会的高级LIGO观测到了无数次黑洞和中子星碰撞，为天体物理、宇宙学、基础物理和核物理中的一系列广泛问题提供了新的线索。通过控制在高激光功率下工作时的热失真效应，并通过降低其测试质量镜膜中的热噪声，可以进一步提高观测站的灵敏度。该奖项资助更好的激光波前变形传感器和致动器的研究，并支持为地球引力波探测器寻找更好的涂层材料的合作研究。这两个研究方向都追求显著扩大高级LIGO观测范围的共同目标。该奖项为学生和博士后提供进入世界级天文台的机会，并为他们担任科学领导职位做好准备。该奖项专门为以下方面提供资金：(I)开发了基于模式转换器的光波前传感器，能够同时检测先进的LIGO探测器的腔对准和模式匹配。(Ii)基于像素解调的相位相机的发展，以高帧速率提供探测器中激光场的高分辨率射频拍频图。该相机用于干涉仪调试和反馈控制。(三)探索高阶波前像差的传感和控制方案。(四)与LIGO实验室合作，继续提供调试支持，以在即将到来的臭氧和O4观测运行中提高高级LIGO的天体物理灵敏度和带宽。(五)为低温节点悬浮液的建造和测试提供安装支持，用于测量低至低温温度的新涂层的机械损失。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
