LCGT Auxiliary Optics System (AOS)

Contents

LCGT Auxiliary Optics System (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

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 LCGT, so we shall, by any means, pack them into the vacuum chambers if required.

Subsystems

Stray Light Control
- Including beam baffles, output Faraday isolators, and calculation of BRDF of test masses...
Beam Reducing Telescopes
Optical Lever
- Optical lever is a kind of local sensors, but unlike other local sensors, it requires long beam lines as lever's arms, thus this should be considerd in AOS.
Viewing Monitors and Illumination
Viewports
Automatic Target System
Beam Mode Profiler
Squeezing system??
Highly related subsystems (not included in AOS)
- Beam Shutters(IOO, MIF)
- Initial Alignment(MIF)
- Local Sensors and Actuators (LIGO's OSEM-like things utilized in vibration isolation system)(VIS)
- Violine mode sensors or Wire position sensors (utilized in vibration isolation system or in noise-hunting phase)(VIS?)
- Other local sensors/monitors/actuators?
Any other optics, outside breadboard,...
