Vacuum & Mechanics

A giant vacuum system is necessary to preserve undisturbed conditions for the critical part of the detector:

  • the laser beam propagates within two 3 km long arms maintained at a residual pressure a trillion times lower than atmospheric pressure;
  • The test masses (the main mirrors) are housed in large vacuum chambers that isolate them from acoustic and damping effects and, not least, preserve the cleanliness of their surfaces.

The Virgo vacuum system is one of the largest ultra-high vacuum systems ever built in the world. Its most impressive feature, perhaps more than its volume, is the extent of its exposed surface area = 24,000 m2. Within this department, different skills combine in a unique team to complete complex and multidisciplinary tasks: management of the vacuum apparatus, management of the vacuum laboratory, management of the workshop and finally the mentioned test facilities. The management of the cryogenic storage facility is also included.
