LCGT Auxiliary Optics Subsystem (AOS)

LCGT Auxiliary Optics Subsystem (AOS)

Objectives

The objectives of the subgroup "Auxiliary Optics System" (AOS) is to have the other LCGT subgroups design and complete the auxiliary optics that physically, logically and consistently glue the main parts of the LCGT interferometer together.

General Description

All the AOS shall be fit to the vacuum chambers that had been already determined when the AOS group was established. Even if the vacuum chamber was not designed for considering the space allocated for AOS, AOS are required for fully operating LCGT, so we should pack them into the vacuum chambers BY ANY MEANS.
