LIGO Document P1100090-v5
- We describe the design of a small optic suspension, referred to as the Tip-Tilt mirror suspension, used to isolate selected small optics for the interferometer sensing and control beams in the Advanced LIGO gravitational wave detectors. The suspended optics are isolated in all 6 degrees of freedom, with eigenmode frequencies between 1.3 Hz and 10 Hz. The suspended optic has voice coil actuators which provide an angular range of ±4 mrad in the pitch and yaw degrees of freedom.
