Optical Sensors and Electromagnetic Actuators (Room Temperature)

Related subgroups: VAC, CRY, VIS


Scope

Sensors and Actuators for 6 DoF motions of the intermediate masses of vibration isolation system Type-B. This is the LIGO's OSEM-like subsystem that consists of an optical sensor and an electromagnetic actuator (OSEM).

<!> Here, the Operating temperature is assumed to be at room temperature, not to be utilized in cryogenic temperature.
