    3. Tev and MI FBI

A. Action items

  Flying wires
    1. If Tev agrees, instrumentation and SDA people want to fly
       every proton injection now that the multiple scattering
       is so much less? It would be useful to test the effect
       on D0 and CDf of flying the thinner wires during a store.
    2. Parasitic studies to adjust for new wires - which will
       measure the losses.
    3. Improve Flying Wire OAC and make it the source of all
       FW emittance calculations.  ( meeting to finalize this
       Wednesday Dec 1, 1:30.)

           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.
           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.
           e) 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.
           f) Get the new stuff into SDA and dataloggers
     4) Can T46 get emittances from OAC?

  synclite
     5. Get the pbar mirror movement into the sequencer.
     6. Do the synclite study plan as outlined in doc 1460.
     7. Learn to use the synclite simulation program
        and compare to diffraction study.
     8. The SL rms as reported by the frontend will not have
        a diffraction contribution subtracted.
     9. Create a synclite OAC analogous to the FW OAC to be the
        source of all synclite emittance calculations.
            a) What to use for diffraction subtraction?
            b. Use ACNET lattice parameters

  Tev FBI
    10. Will need calibrating, maybe a timing adjustment due
        Resistive wall monitor changes.

  MI FBI

      11. Add a pbar sample and hold intensity analagous
         to the proton qualifier.

B. Details

    1. Tev FBI.
         a) moved to the other RWCM (resistive wall current monitor).
            The RWCM has been rebuilt.  It still has the same share
            of the signal.  This was done so the SBD can have it's
            own RWCM. ( See document 1475 which has a diagram.)
         b) Calibration will be needed since RWCM is rebuilt.
         c) Timing may need adjustment.
         d) No changes in ACNET variables, except for the
            calibration OAC
         e) No dedicated studies needed.
    2. MI FBI - no changes
    3. Flying wires - See document 1464
         a) E11 has 7 micron wires
         b) see action items above.
    4. Synclite
         a) see Document 1460
         b) see action items above.
