![Clean area and vacuum enclosure for a new bench of Advanced Virgo (January 2016)](http://public.virgo-gw.eu/wp-content/grand-media/image/AdVirgo_MinitowerSNEB_CleanArea_201601_0064.jpg)
The researchers are preparing the optical bench to be inserted inside the vacuum enclosure and suspended to the mechanical attenuator on top of the enclosure, called minitower. A clean area has been built around the minitower to keep the optical elements out of dust.
