KAGRA Auxiliary Optics System

Objectives

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

General Description

• Most of 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 considering the space allocated for AOS, AOS are required for fully operating KAGRA, so we shall, by any means, pack them into the vacuum chambers if required.
