Abstract

We outline a proposed precision experiment in fundamental physics, emphasizing the engineering requirements in the construction of the equipment. The objective of the experiment is to detect a predicted finite range gravitational force commonly called the "Fifth Force". Its execution involves measuring the earth's gravitational field vector at a large number of precisely located points (to 0.1 mm) around a closed surface. We will explain the basic idea behind the design and its advantages over previous experiments and state the accuracy requirements of various components. We will also describe two conceptual designs of the position and motion-control device.
