Vibration Isolation System (VIS)

Subsystem Definition

  • This subsystem makes vibration isolation for all optics used in KAGRA.
  • The test mass mirrors are cooled to 20K through heat links. Though the mechanical design for the cryogenic suspensions is included by the task of this subsystem , the final stage which consists of a sapphire mirror and sapphire wires is provided by the cryogenic subsystem. The heat links are not included in this subsystem either.
