Weak Equivalence Principle Test on a Sounding Rocket
Abstract
SR-POEM, our principle of equivalence measurement on a sounding rocket, will compare the free fall rate of two substances yielding an uncertainty of 10-16 in the estimate of η. During the past two years, the design concept has matured and we have been working on the required technology, including a laser gauge that is self aligning and able to reach 0.1 {pm/}√ {{Hz}} for periods up to 40 s. We describe the status and plans for this project.
