Description
Most of the Advanced Virgo light sensing devices are located on 5 in
vacuum suspended benches. The benches are suspended from a triple
stage mSAS suspension, and the angular degrees of freedom are sensed
and controlled from the ground using LVDTs and coil-magnet
actuators. The angular control has stringent requirements 30 nrad rms
and 3e-15 rad/rtHz above 10 Hz. After introducing the system design,
we present the first in air results of controlling the fully
integrated system and striving to achieve these requirements.
