Vibration Isolation System (VIS)

Subsystem Definition

This subsystem makes vibration isolation for all optics used in KAGRA.
Requirement of displacement of the test mass mirrors must be less than 4x10^-20m/rtHz at 10Hz. RMS motion must be less than 0.1 um as displacement and 0.1 um/s as velocity.

- * 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.
