KAGRA Auxiliary Optics System (AOS)

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.

   * <!> Auxiliary cavity-locking system (Green laser one) itself should be considered in MIF or IOO. The effort of system designing should be separated from that of engineering and fabricating from the WBS point of view (or what-you-call system engineering) even if the person assigned to both is the same.
