This Page describes the forward plans and measurements to do with DC Readout/OMC at the 40m.

Re-establish the IFO state (ie, get back to where we were with respect to RF locking)
 . MC beam 
 . imact on AS RF beamline; getting on to all the PDs and recommissioning the signals
 . impact of new controls electronics on existing RFM / DAQ

Tweak the input mode matching telescope, to match the input mode to the average of the two arms rather than just the x-arm, as it is now.

Test/familiarize the new digital controls systems:

 . Familiarize ourselves with the new MEDM screens, Rob will make them better & talk with Rolf about autogen
 . Integration with the current RFM network, Dataviewer, DTT, and tds tools for scripting (all new stuff at 32kHz)
 . Integration with the current LSC processor for global control (ie DARM on DC)
 . Test control outputs (for DC biases/controls of all PZTs)
 . Test dither outputs for all PZTs
 . Test/characterize the ADCs and whitening filters, do a channel checkout

Commission the OMC

  (0) Instrument the OMC reflected beamline with QPD and camera and photodiode.
 . (1) Find the OMC transmitted light on the AS table
  . Lock the bright michelson IFO
  . Sweep the cavity with triangle wave, maximize the transmission of
  . some peak by steering the PZTs, and find that on the AS table.  Alternatively, sweep
  . the cavity, while rastering the TTPZTs over their full range at
  . four different frequencies, to find the transmitted spot.  Then
  . set up the CCD camera, and route the video feed into the control room.
 (2) Lock the OMC to a TEM00 mode and commission the OMC-ASC dither system.
  . Once the dither system is working, mode match the IFO darkport beam to the
  . OMC by tweaking the Output Mode Matching Telescope.  This should be trivial if
  . the dither-alignment system is working.  Disconnect the picomotor.
 

Commission DC Readout

  (1) Establish DC Readout using a simple Michelson.
   . Handoff control of DARM to the OMC transmitted light.  Measure both
   . inside and out-of-loop noise (phase noise), and compare with RF.  Study
   . compensation for the quadratic portion of the error signal.  Study noise
   . couplings for the two readout techniques (laser noise, alignment, ...?).

  (2) DC Readout with a Power-Recycled Fabry Perot Michelson
   . Strategy the same as (1), above, but we'll also have to perfect the
   . no-bang locking for this configuration along the way,
   . using 33 MHz RFPD at AS port.  

  (3) DC Readout with Dual-Recycled Michelson Interferometer.

  (4) DC Readout with a Power-recycled RSE interferometer.


Comission DC ASC for full IFO

   . This will involve stealing the current, mostly useless ASC system, 
   . and re-configuring it in the style of the new OMC computer.  Thus, it
   . will have inputs from some diodes around the system (probably network
   . traffic from LSC diodes will be fine, but maybe we'll also want to retain
   . some QPD signals), and a sizable set (14?) of digital lock-in systems, with
   . input and output matrices, that will allow us to route dither/feedback signals
   . to all the suspension ASC inputs.
