Continued U.S.-New Zealand Cooperative Effort on the Canterbury Ring Laser

该奖项支持俄克拉荷马州立大学的汉斯·R·比尔格博士和克赖斯特彻奇坎特伯雷大学的G·E·斯特德曼博士继续合作研究，以完成坎特伯雷大学平面1平方米高分辨率环形激光器的建造和运行，以及坎特伯雷大学略小的环形(898毫米×837毫米)的原型。并利用该仪器测量地震作用和固体潮等地球物理效应。该合作始于，获奖号为INT-00033，是比尔格博士的实验技能与斯特德曼博士在使用环形激光测量地球物理、原子光谱和一般相对论效应方面的更多理论兴趣的富有成效的结合。用环形激光感测和记录固体潮汐和地震活动是一种新颖的方法，应该会大大促进该仪器对这些应用的评估。此外，环形激光的位置应该允许从附近非常活跃的太平洋板块-印度板块边界更准确地测量地震活动。

This award supports continued cooperative research between Dr. Hans R. Bilger of Oklahoma State University and Dr. G.E. Stedman of the University of Canterbury, Christchurch, to complete construction and attain operation of a plane, square 1 m2 high- resolution ringlaser and of a prototype of a slightly smaller ring (898 mm X 837 mm) at the University of Canterbury, and to use the instrument to measure geophysical effects such as seismic action and earth tides. The collaboration, begun in 1989 under award number INT 89-00033, is a productive blend of the experimental skills of Dr. Bilger with the more theoretical interests of Dr. Stedman regarding the use of ringlasers to measure geophysical, atomic spectroscopic, and general relativistic effects. Sensing and recording earth tides and seismic activity with a ringlaser is novel, and should significantly advance assessment of the instrument to these applications. In addition, the site of the ringlaser should allow more exact measurement of seismic activities from the nearby, very active, Pacific Plate-Indian Plate boundary.
