Advanced Virgo suspended optical bench inside its vacuum enclosure (January 2016))

The researcher is tuning the position of a mirror on an optical bench. For Advanced Virgo, new optical benches have been suspended and put in vacuum. The mechanics of the suspension is visible on the top part still opened. On-board electronics is attached below the suspended bench to reduce the number of (white) electrical cables going along the suspension.

Mechanical filter of a superattenuator (January 2016)

Superattenuators are used to suspend the main interferometer mirrors and benches to isolate them from the seismic ground vibrations. Here, a mechanical attenuator, part of a superattenuator, is being installed. The attenuator is then enclose in a vacuum tower.
