We describe an inertial rotation sensor with a 30-cm cylindrical proof-mass suspended from a pair of 14-μm thick BeCu flexures. The angle between the proof-mass and support structure is measured with a pair of homodyne interferometers which achieve a noise level of ∼ 5 prad/√(Hz). The sensor is entirely made of vacuum compatible materials and the center of mass can be adjusted remotely.
