Wire Position Sensors or Violine mode monitors (Room Temperature)
Related subgroups: VIS, VAC, CRY
Proper name for this subsystem should be discussed based on its primal functionality.
Contents
Scope
Senising absolute position of the wires utilized in vibration isolation system. With the sensor's output, we can determine the (absolute?) position of each test mass.
Operating temperature: here the system is assumed to be utilized at room temperature, not in cryogenic temperature.
Applicable Documents
Not yet be determined well.
General Description
Not yet be considered well.
Functions
- Sensing absolute motions of the wires used in the vibration isolation system.
Even if the Vibration Isolation subgroup decides that the priority of this subsystem would be low, we would need such system in the commissioning phase of LCGT or after that.
