  1845   Thu Aug 6 17:51:21 2009 ChrisUpdateGeneralDisplacement Sensor UpdateFor the past week Dmass and I have been
ordering parts and getting ready to construct
our own modified version of EUCLID (figure).

mechanical noise we might get with a non-suspended
cavity. My guess is that the PMC is better

  13512   Sun Jan 7 03:22:24 2018 KojiUpdatePonderSqueezeDisplacement requirements for short-term squeezingInteresting. My understanding is that this
is close to signal recycling, rather than
resonant sideband extraction. Is that correct?
  
  13513   Sun Jan 7 11:40:58 2018 KevinUpdatePonderSqueezeDisplacement requirements for short-term squeezingYes, this SRC detuning is very close to
extreme signal recycling (0° in this
convention), and the homodyne angle is close
  
  13514   Sun Jan 7 17:27:13 2018 gautamUpdatePonderSqueezeDisplacement requirements for short-term squeezingMaybe you've accounted for this already
in the Optickle simulations - but in Finesse
(software), the "tuning" corresponds
  
  13515   Sun Jan 7 20:11:54 2018 KojiUpdatePonderSqueezeDisplacement requirements for short-term squeezingIn fact, that is my point. If we use signal
recycling instead of resonant sideband extraction,
the "tuning" of the SRC is opposite
