This research has had two objectives 1 to study the application of cryogenic technology to the problem of gravity gradient measurements, and 2 to use such a gradiometer to make more accurate measurements of the inverse square law of gravity to test the recent experimental and theoretical suggestions that the inverse square law of gravity might be violated at laboratory distances. Since room temperature gradiometers are ultimately limited by room temperature Brownian motion, we have been experimenting with a laboratory cryogenic gradiometer which could lead to the development of a more sensitive moving baseline gradiometer for field use. Such gradiometers could have applications to problems in navigation and modeling of the earths gravitational field.
