We describe SR-POEM, a Galilean test of the weak equivalence principle (WEP), 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 WEP measurement is made with a set of four laser gauges that are expected to achieve 0.1 pm Hz–1/2. We address the two sources of systematic error that are…

We describe SR-POEM, a Galilean test of the weak equivalence principle that is to be conducted during the free fall portion of the flight of a sounding rocket payload. This test of a single pair of
Reduction of magnetic perturbation for SR-POEM
SR-POEM is a Galilean test of the weak equivalence principle(WEP) that aims to measure the fractional acceleration difference $\eta$ with a mission uncertainty $\sigma(\eta)=1\times 10^{-17}$for a
Aligning a reflection cavity by Anderson's method.
It is shown that Anderson's alignment method can be used in reflection, but that it requires that the Fabry-Perot cavity have mirrors with significantly unequal reflectivities.
Analysis of Kelvin Probe operational models with application to SR-POEM
We present a study of several models on which Kelvin Probe (KP) instruments with flat and spherical tips rely for operation and for the determination of the contact potential difference (CPD). The
Quantum test of the equivalence principle and space-time aboard the International Space Station
We describe the Quantum Test of the Equivalence principle and Space Time (QTEST), a concept for an atom interferometry mission on the International Space Station (ISS). The primary science objective
Studying Antimatter Gravity with Muonium
The gravitational acceleration of antimatter, ḡ, has yet to be directly measured; an unexpected outcome of its measurement could change our understanding of gravity, the universe, and the possibility
Subpicometer length measurement using semiconductor laser tracking frequency gauge.
We have demonstrated heretofore unattained distance precision of 0.14 pm (2 pm) incremental and 14 nm (2.9 μm) absolute in a resonant (nonresonant) interferometer at an averaging time of 1 s, using
Small Angle Approximation for Non-parallel Plate Capacitors with Applications in Experimental Gravitation
An approximate analytical formula for the capacitance of a non-parallel plate capacitor with small values of inclination angles and distance separations of the plates is presented. Most applications
Runaway Domain Wall and Space-time Varying alpha
Recently spatial as well as temporal variations of the fine structure constant alpha have been reported. We show that a "runaway domain wall", which arises for the scalar field potential without


A weak equivalence principle test on a suborbital rocket
We describe a Galilean test of the weak equivalence principle, to be conducted during the free fall portion of a sounding rocket flight. The test of a single pair of substances is aimed at a
STEP. A Satellite Test of the Equivalence Principle.
STEP is one of a number of missions now being developed to take advantage of the quiet space environment to carry out very sensitive gravitational experiments. Using pairs of concentric free-falling
“Galileo Galilei” (GG) a small satellite to test the equivalence principle of Galileo, Newton and Einstein
Abstract“Galileo Galilei” (GG) is a small satellite designed to fly in low Earth orbit with the goal of testing the Equivalence Principle—which is at the basis of the General Theory of Relativity—to
Test of the equivalence principle using a rotating torsion balance.
By analyzing the data for accelerations towards the center of the Milky Way the authors find equal attractions of Be and Ti towards galactic dark matter, yielding eta(DM,Be-Ti)=(-4+/-7)x10(-5).
Kelvin probe measurements: investigations of the patch effect with applications to ST-7 and LISA
One of the possible noise sources for the space-based gravitational wave detector LISA (the Laser Interferometer Space Antenna), associated with its test masses, is that due to spatial variations in

A continuously rotating torsion balance is used to make new tests of the universality of free fall (UFF) and yields a nearly model-independent test of the UFF for gravitational binding energy at the 1% level.
