A six degree-of-freedom fused silica seismometer: design and tests of a metal prototype [PDF]
Class. Quantum Grav. 39 015006 (2022), 2021 Ground vibrations couple to the longitudinal and angular motion of the aLIGO test masses and limit the observatory sensitivity below 30 Hz. Novel inertial sensors have the potential to improve the aLIGO sensitivity in this band and simplify the lock ...
