Subject: Readiness Meeting Minutes - WCM and IPM - 2/2/99

V124 Status - Heather Hartmann
        - five V124's will be available in the first production run. exact
                availability date is not yet clear. of these five, Heather
                keeps one and one goes to RF. Beam Instrumentation gets
                three, one each for WCM and IPM and one as a
                portable unit in the mini-VME crate.
        - first V124 has been wrung out and released to Larry Hoff to see
                how the ADO plays.
        - next four V124's are being stuffed. Work will then wait for the
                results of Larry's testing.


IPM status - Roger Connolly
        - Four detectors are installed in beamline.
        - Preamplifier circuit boards are built and tested. Boards are to
               be assembled by outside vendor. Work will be started 2/4.
               Delivery time is expected to be four weeks.
        - Preamp mounting chassis are being built.
        - All cables are in house and cable installation is in progress.
        - VME digitizers are in house awaiting acceptance testing.
        - The parts for two magnets are out of the shop.
        - A conceptional design for mounting stands for magnets has been
                approved.
        - Signal cable termination is in progress.
        - The voltage divider box has been designed.

WCM Status - Peter Cameron
        Hardware
                - enclosures are though the shops and out for iriditing.
                - combiner boards have been received from the vendor.
        Timing
                - control of the V124 has been shifted from Pete via
                        LabVIEW/MXI/VME to Roger Lee in the ADO.
                - there was considerable discussion of timing problems
                        resulting both from having only one V124 for two
                        rings, and from having only one scope for two
                        rings. The consensus was that separate v124/scope
                        for each ring is the best solution to these
                        problems. Workarounds for day
                        one are under discussion.
                - acquisition mode zero has been created, to permit
                        auto-triggered operation. When V124 triggers are
                        not available, auto-triggered data will be written
                        to shared memory for processing by the application.
                        In addition, to simplify development and
                        trouble-shooting a real-time LabVIEW generated
                        waterfall display will be available as a web page.
        LabVIEW
                - vi's written to read command block and use command block
                        data to set up scope, and to write status block.
                - work in progress to implement acquisition mode zero
                        using generated data.

ADO Status - Roger Lee
    What we have
        1.Working Command/Status blocks
              (FEC & WCM communicate via shared memory)
        2.Dynamic circular buffers
              (one buffer is an acquisition = profile length * # profiles)
        3.Each buffer has header with parameters used for acquisition
              (sample rate, length, # profiles, trigger specs, etc.)
        4.ADO for BLUE control and for YELLOW control
              (each have 16 mbytes of shared memory)
        5.ADO parameters have RTDL time stamps
    Concerns
        FEC to WCM computer
            1.How to synchronize start of an acquisition
                     (FEC controls V124, WCM computer controls scope)
            2.How do we fill in beam time stamps
                     (course comes from V108, fine from V124)
            3.How to alternate between blue and yellow acquisitions
                     (there is only one scope with one trigger)
        FEC to CLC (applications)
            1.How does CLC know how many buffers are available
            2.How can CLC read/reread old buffers
        GENERAL
            1.Need a wcmMasterAdo to control acquisition from both
                        BLUE and YELLOW
            2.How is it possible to use 1 V124 for both blue and yellow
