Subsystem: Auxiliary Optics

Auxiliary optics include a number of systems that support the alignment, control and calibration of LIGO's gravitational wave interferometers. The unifying theme for the AOS work is in-vacuum optical layout and beam transport. AOS components include the following:

[aos]
      TCS ring heater bake load

[aos]
    Output Faraday isolator measurement

[aos]
  HAM auxiliary suspensions

[aos]
      Cryopump baffle suspension spring

[aos]
    Thermal compensation picomoters

[aos]
  Photon calibrator periscope

[aos]
      Ring heater on large optic

[aos]
    Covered TCS steering mirror

[aos]
  Photon calibrator periscope

[aos]
      TCS ring heater assembly

[aos]
    Optical lever pier

[aos]
  Mode cleaner baffle installation

[aos]
      Early TCS Hartmann sensor

[aos]
    TCS ring heater

[aos]
  Heat distribution on eLIGO ITM
