 1. This subsystem makes vibration isolation for all optics used in KAGRA.
 2. 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.

Vibration Isolation System (VIS)

Subsystem Definition

  1. This subsystem makes vibration isolation for all optics used in KAGRA.
  2. 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.
