A quick test of the WEP enabled by a sounding rocket

We describe SR-POEM, a Galilean test of the weak equivalence principle, which is to be conducted during the free fall portion of a sounding rocket flight. This test of a single pair of substances is aimed at a measurement uncertainty of σ(η) < 10-16 after averaging the results of eight separate drops, each of 40 s duration. The weak equivalence principle measurement is made with a set of four laser gauges that are expected to achieve 0.1 pm/\sqrt{Hz}. We address the two sources of systematic error that are currently of greatest concern, magnetic force and electrostatic (patch effect) force on the test mass assemblies. The discovery of a violation (η\not= 0) would have profound implications for physics, astrophysics and cosmology.

Weak Equivalence Principle Test on a Sounding Rocket

SR-POEM, our principle of equivalence measurement on a sounding rocket, will compare the free fall rate of two substances yielding an uncertainty of E-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 per root hertz for periods up to 40 s. We describe the status and plans for this project.
