Modulated Source Eotvos Experiment (Physics)

一个异常敏感的调制源Eotvos实验将在华盛顿东部斯内克河的一个大水闸旁进行，以限制中距离依赖于物质的“引力”的存在。作者在1988年夏天进行的一个原型实验对积极的“第五种力”效应进行了限制。用一个明确的测量来解决这种可能性是很重要的。一个已经在耶鲁大学组装并已经用于原型实验的便携式实验室将在1990年夏天被转移到小鹅锁进行进一步的测量。钟摆设计的改进将使实验的灵敏度至少比原型实验高一个数量级，预计新的测量将对这种效应的存在设定明确的限制。

An unusually sensitive modulated-source Eotvos experiment will be conducted next to a large lock on the Snake River in eastern Washington to put limits on the existence of an intermediate-range material-dependent "gravitational" force. A prototype experiment conducted by the author during the summer of 1988 placed limits on a positive "Fifth Force" effect. It is important to settle this possibility with a definitive measurement. A portable laboratory already assembled at Yale University and already used in the prototype experiment will be moved to the Little Goose Lock during the summer of 1990 for further measurements. Improvements in the pendulum design will make the experiment at least one order of magnitude more sensitive than the prototype experiment and it is expected that the new measurements will set definitive limits on the existence of this effect.
