Benefits of SPI

Here is a list of the benefits of SPI.
Inside ( ) are alternative techniques.

Reduction of the RMS motion of the mirrors

  • Easier lock acquisition (Pre-locking of the arms)
  • Stabler operation (Hierarchical control)
  • Less up conversion noise (Hierarchical control)
  • Less laser noise coupling (Hierarchical control)
  • Less actuator noise (Hierarchical control)

Reduction of the seismic noise

  • Low frequency seismic noise
  • Vibration introduced from the heat link (Better heatlink isolation. Local SPI.)
