Automatic Target System

Contents
Scope
The scope of Automatic Target System is to provide targets on the way of a beam line, and to be used for the alignment of the beam line in the interferometer. This system helps commissioning phase, and will be turned off during the observation mode.
For example, each arm cavity should have this system. Several targets will be located in the arm tube, and have an accessible human interface for operators to easily and remotely turn them on/off from the center room.
Applicable Documents
None.
General Description
This kind of system has been already developed and practically used in TAMA300. Each unit of target system consists of an liner feed-through (as a manipulator) and a circle plate (as a target head) with a center hole, where a part of beam can pass through even when the target is tuned on. The linear feed-through is driven by pressure air then.
For KAGRA, the motion drive source will be a motor(?).
Functions
TBD
Naming Conventions
TBD
Locations
- X-arm tube
- Y-arm tube
For each arm, preliminary locations of targets is shown in JGW-T1200816
Requirements
- It should be remotely turned on/off.
- It should be viewable (not necessarily visual) when the target head is illuminated by IR/green lasers. Note that these laser powers for initial alignment would be somewhat smaller.
