项目摘要

Advanced LIGO transformed gravitation, astrophysics and cosmology by opening the gravitational- wave window on the universe, establishing a new paradigm for multimessenger observations. The scientific case for constructing a network of 3rd generation ground based interferometric gravitational wave detectors with about a factor 10X sensitivity improvement is compelling. The detectors would observe all the compact binary coalescences in the universe and bring the new field into cosmological research. The most realistic way to improve the detectors is by increasing the length of the interferometer arms as the gravitational wave signals grow with the length while most of the significant limiting noise is independent of, or varies slowly, with the length. A significant fraction of cost of the detectors will be in the ultra-high vacuum (UHV) system needed for the beam tubes and the civil work in preparing the site. The group proposes to explore a range of concepts in vacuum technology that could reduce the cost of UHV tube systems by a factor of about 2X, amounting to a saving of $200M to $300M in a 3rd generation detector. The program will explore novel techniques to economically fabricate vacuum systems using and building on the latest metallurgical and materials science innovations. The investigations will be conducted in collaboration with the DOE (FNAL) and an international partner (CERN). Successfully identifying novel fabrication approaches and beam tube designs will have applicability beyond the immediate interests of gravitational wave astrophysics. Next generation high energy colliders that dwarf the LHC will also need innovative concepts for their vacuum infrastructure. The applicability of the material coatings research that will be explored also promises to have an economic impact in the use of coated steels for various industrial applications. The initiative here, to enable the construction of 3rd generation detectors, will generate new opportunities to attract, inspire and educate future scientists, citizens and leaders.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.
先进的LIGO通过打开宇宙的引力波窗口,改变了引力学、天体物理学和宇宙学,建立了多信息观测的新范式。构建第三代地面干涉引力波探测器网络的科学理由是令人信服的,灵敏度提高了约10倍。探测器将观测宇宙中所有致密的双星聚结,并将这一新领域带入宇宙学研究。改进探测器最现实的方法是增加干涉仪臂的长度,因为引力波信号随长度增长,而大多数重要的极限噪声与长度无关,或随长度缓慢变化。探测器的很大一部分成本将用于束管所需的超高真空(UHV)系统和场地准备的土木工程。该小组提议探索真空技术中的一系列概念,这些概念可以将特高压管道系统的成本降低约2倍,相当于在第三代探测器上节省2亿至3亿美元。该计划将探索利用最新的冶金和材料科学创新来经济地制造真空系统的新技术。调查将与能源部(FNAL)和一个国际合作伙伴(CERN)合作进行。成功识别新的制造方法和束管设计将具有超越引力波天体物理学直接利益的适用性。让大型强子对撞机相形见绌的下一代高能对撞机也需要为其真空基础设施提供创新的概念。将探索的材料涂层研究的适用性也有望对各种工业应用的涂层钢的使用产生经济影响。这项旨在建造第三代探测器的倡议将创造新的机会来吸引、激励和教育未来的科学家、公民和领导者。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。
