A Vacuum-Compatible Cylindrical Inertial Rotation Sensor with Picoradian Sensitivity
M. P. Ross, J. van Dongen, Y. Huang +15
We describe an inertial rotation sensor with a 30-cm cylindrical proof-mass suspended from a pair of 14-m thick BeCu flexures. The angle between the proof-mass and support struc…
A Cryogenic Torsion Balance Using a Liquid-Cryogen Free, Ultra-Low Vibration Cryostat
S. M. Fleischer, M. P. Ross, K. Venkateswara +5
We describe a liquid-cryogen free cryostat with ultra-low vibration levels which allows for continuous operation of a torsion balance at cryogenic temperatures. The apparatus uses…
Point Absorber Limits to Future Gravitational-Wave Detectors
W. Jia, H. Yamamoto, K. Kuns +198
High-quality optical resonant cavities require low optical loss, typically on the scale of parts per million. However, unintended micron-scale contaminants on the resonator mirrors…
LIGOs Quantum Response to Squeezed States
L. McCuller, S. E. Dwyer, A. C. Green +194
Gravitational Wave interferometers achieve their profound sensitivity by combining a Michelson interferometer with optical cavities, suspended masses, and now, squeezed quantum sta…
Point absorbers in Advanced LIGO
Aidan F. Brooks, Gabriele Vajente, Hiro Yamamoto +198
Small, highly absorbing points are randomly present on the surfaces of the main interferometer optics in Advanced LIGO. The resulting nano-meter scale thermo-elastic deformations a…
A Low-Frequency Torsion Pendulum with Interferometric Readout
M. P. Ross, K. Venkateswara, C. A. Hagedorn +6
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 syste…
