WORKING DRAFT ON TRANSVERSE EMITTANCE oacS - nOV 30, 2004

   1. FW emittance OAC (Nate)

          a) create ACNET variables with for the current best
             lattice parameters for injection, flattop,
             low beta.  Set them to the values in doc 1465,
             with the idea that they will eventually come
             from the measured twiss parameter
             database.  Datalog and store in SDA Conditions case.

             ACNET variables with design lattice parameters?

          b) Remove emittance calculation from FE.  Put this
             flying wire only emittance calculation into the
             OAC.  Use ACNET lattice parameters.
          c) Keep the uncoupled emittance calculation for
             E11 and E17 using the SBD for dp/p in the OAC,
             use ACNET lattice numbers, but uncoupled
             approximation?
          d) Add new coupled emittance calculations to the OAC
             as defined in Doc 1465 and use the ACNET lattice
             numbers.
 Added--> e) Does anyone need emittances with design parameters?
          f) Have the OAC give the freshness number of the data it
             uses for its emittance calculations as an "OAC
             freshness number" so the two can be compared to
             look for synchronization problems.
          g) Get the new stuff into SDA and dataloggers


   2) what to do with T46 - Nate will have a proposal tomorrow

   3) Synclite OAC (Randy)
          a) part of FW OAC or separate?
          b) What to use for diffraction subtraction?
          c) Use ACNET lattice parameters
          d) do we also need emittances using
             design lattice parameters
