Improved Torsion Pendulum for Ground Testing of LISA Displacement Sensors
arXiv:gr-qc/0411049 · doi:10.1142/9789812704030_0258
Abstract
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 net forces and therefore provides a more representative test of the noisy forces and parasitic stiffnesses acting on the test mass as compared to previous ground-based experiments. We also discuss a specific application to the measurement of thermal gradient effects.
