TCS

  • What thermal lensing @ 120K?
  • back of the envelope calculation
  • TCS design must: robust, flexible
  • Actuators
    • RHs:
  • Ok with room temperature TMs, what with cryogenics?
  • AdV design optimized to have the best uniformity:for ET segmented RH for higher order aberrations control (astigmatism)?
    • Recycling cavity projectors:
  • What material/temperature for CPs?
  • New wavelengths and lasers?
  • Thermal actuators? Depends on CP material…
  • LG33 modes require new approaches to compensating beam shaping.
  • Sensors
  • Adaptive optics for squeezing
    • Filter cavities tuning to improve MM: RHs may be the best option
    • Thermal actuators for squeezing beam MM before FC
    • Actuation on FC mirrors for reducing losses from mirrors figure errors
