U.S.-China Cooperative Research: Program to Search for Gravitational Radiation

斯坦福大学的彼得·迈克尔逊和中山大学的胡恩科开展了这项为期两年的美国-中国引力辐射研究项目，目的是协调实验，在斯坦福大学和中山大学现有的探测器之间探测引力波。最终目标是确定引力辐射的存在，引力辐射是能量的一种基本形式，爱因斯坦和其他人在60多年前就预测了引力辐射的存在。调查人员将继续两年前在美国-中国项目下开始的合作。他们建议与现有探测器进行长期(一年)的符合观测，改进低温(冷温)探测器的技术，并开始低频重力波探测器的可行性研究。在中国东南部建立探测器对这一国际实验工作具有重要意义，因为地理上分散的探测器建立同步重合是成功探测重力波的关键。中国东南基地的建立填补了全球探测器网络的一个地理空白。这一巧合实验的结果也有望为探测器技术的进步做出贡献。该项目实现了美国-中国计划的目标，即通过美国和中国科学家的共同努力和能力，促进互惠研究，以促进科学知识的发展。

The objective of this two-year U.S.-China research project on gravitational radiation between Peter Michelson, Stanford University and Enke Hu of Zhongshan University is to coordinate experiments to detect gravity waves between existing detectors at Stanford and Zhongshan University. The ultimate objective is to establish the existence of gravitational radiation, a fundamental form of energy, whose existence was predicted by Einstein and others over sixty years ago. The investigators will continue collaboration that began two years ago under the U.S.-China Program. They propose to carryout a long-term (one-year) coincidence observation with existing detectors, work on improving technology of cryogenic (cold temperature) detectors and begin a feasiblity study of a low frequency gravity wave detector. The establishment of a detector in Southeast China is signi>icant for this international experimental effort since it is essential for the successful detection of gravity waves that geographically dispersed detectors be used to establish simultaneous coincidences. The establishmen> of a base in Southeast China fills a geographical gap in the worldwide detector network. Results from the coincidental experiment are expected to contribute to the advancement of detector technology as well. This project fulfills the U.S.-China Program's objective of promoting mutually beneficial research to advance scientific knowledge through the combined efforts and abilities of American and Chinese scientists.
