An Improved Torsion Balance Test of the Equivalence Principle Towards the Sun
M. P. Ross, E. A. Shaw, C. Gettings +3
We search for violations of the Equivalence Principle towards the Sun using a rotating torsion balance apparatus. We set 95\%-confidence limits on violations with beryllium and alu…
A Search for Ultra-Light Vector Dark Matter with a Rotating Torsion Balance
M. P. Ross, E. A. Shaw, C. Gettings +3
We search for ultra-light vector dark matter interacting with a rotating torsion balance with a baryon minus lepton number composition dipole. Our search spans candidate masses in…
Probing For Non-Gravitational Galactic-Range Dark Matter Interactions
M. P. Ross, S. K. Apple, E. A. Shaw +3
Dark matter remains a mystery in fundamental physics. The only evidence for dark matter's existence is from gravitational interactions. We operated a precision torsion balance expe…
Demonstration of the minimal coupling of horizontal accelerations to rotations in a torsion balance suspended from three wires
Amit Singh Ubhi, Clive C. Speake, Emilia Chick +1
The Cavendish torsion balance is the instrument of choice for measuring weak forces, such as gravity. Although torsion balances have extremely high sensitivity for measuring forces…
Test of the Equivalence Principle for Superconductors
M. P. Ross, S. M. Fleischer, I. A. Paulson +9
We searched for violations of the weak equivalence principle using a cryogenic torsion balance with a pendulum comprised of superconducting niobium and copper. We constrain the Eöt…
A Method for Reducing the Adverse Effects of Stray-Capacitance on Capacitive Sensor Circuits
Conner Gettings, Clive C. Speake
We examine the increase in voltage noise in capacitive sensor circuits due to the stray-capacitance introduced by connecting cables. We have measured and modelled the voltage noise…
