Seismic Isolation Subsystem Design Requirements Document

Document #:

LIGO-E990303-v1

Document type:

E - Engineering documents

Abstract:

Isolation of the LIGO II [now Advanced LIGO] optics from ambient vibration is accomplished by the Seismic Isolation (SEI) Subsystem and the Suspension Subsystem. This document gives the requirements for the SEI subsystem, including requirements for interfacing to the suspension subsystem.
