dc.description.abstractWe describe a torsion pendulum with a large mass-quadrupole moment and a resonant frequency of 2.8 mHz, whose angle is measured using a Michelson interferometer. The system achieved noise levels of ∼200prad/Hz⎯⎯⎯⎯⎯√ between 0.2 and 30 Hz and ∼10prad/Hz⎯⎯⎯⎯⎯√ above 100 Hz. Such a system can be applied to a broad range of fields from the study of rotational seismic motion and elastogravity signals to gravitational wave observation and tests of gravity.en_AU
