“…Although other instruments are much more sensitive to gravitational waves 21 , this apparatus can be used as a prototype for future torsion-balance based gravitational wave detectors. 10 Additionally, this instrument may allow for the study of atmospheric gravity gradient noise 22 with the addition of an identical orthogonally-oriented apparatus.…”

We describe a torsion pendulum with a large mass-quadrupole moment and a resonant frequency of 2.8 mHz, whose angle is measured using a modified Michelson interferometer. The system achieved noise levels of ∼ 200 prad/ √ Hz between 0.2-30 Hz and ∼ 10 prad/ √ 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.

We 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.
