Characterization of disturbance sources for LISA: torsion pendulum results
L. Carbone, A. Cavalleri, R. Dolesi +4
A torsion pendulum allows ground-based investigation of the purity of free-fall for the LISA test masses inside their capacitive position sensor. This paper presents recent improve…
Measuring the LISA test mass magnetic proprieties with a torsion pendulum
M. Hueller, M. Armano, L. Carbone +5
Achieving the low frequency LISA sensitivity requires that the test masses acting as the interferometer end mirrors are free-falling with an unprecedented small degree of deviation…
Improved Torsion Pendulum for Ground Testing of LISA Displacement Sensors
L. Carbone, A. Cavalleri, R. Dolesi +4
We discuss a new torsion pendulum design for ground testing of prototype LISA (Laser Interferometer Space Antenna) displacement sensors. This new design is directly sensitive to ne…
Measuring random force noise for LISA aboard the LISA Pathfinder mission
D. Bortoluzzi, L. Carbone, A. Cavalleri +6
The LTP (LISA Testflight Package), to be flown aboard the ESA / NASA LISA Pathfinder mission, aims to demonstrate drag-free control for LISA test masses with acceleration noise bel…
