       Status of the Project

      Good News
        » Funding of $1.4B approved (incl $60M for Controls)
        » FY01 Funding of $278M approved (incl $9.5M for Controls)
        » 1.4 million yard of dirt moved, first concrete poured




      Unresolved Issues
        » Pre-operations funding
        » Some controls staffing problems at BNL and LANL
        » Who is the President (and is he from Tennessee…)???


SNS Integrated Control System
     An aside…




SNS Integrated Control System
                  We plan a system fully
           integrated under EPICS, including…
        Accelerator Systems
         » Front End, Linac, Compressor Ring, Beamlines
         » ~ 50,000 channels, 160 IOCs
         » Front End already running under EPICS (at Berkeley)
        Target System
         » Large and complex liquid Mercury Target
         » 1000 channels, 6 PLCs
         » Test facility already running prototypical EPICS system
        Conventional Facilities
         » 2500 channels, 10 PLCs, 150 screens
         » To be done in EPICS by Sverdrup in Tullahoma
         » Training in January


SNS Integrated Control System

     Some things we have agreed upon…

        Site-wide Device and Signal Naming Convention
        ControlLogix PLCs (Allen-Bradley)
         » ControlNet over EtherNet Driver
        Standard Cabinets
        PowerPC IOCs (MVME 2100)
        VME64x (Bid on the street)
         » Including Utility Board
        Linux Environment where appropriate
        Oracle, but…


SNS Integrated Control System
     … and some we have not.


         Display Manager
          » DM2K (The current “official” standard) vs EDM
         Database creation
          » Will use Oracle, but the process is uncertain
              – Capfast??
              – Templates?




         We hope this meeting will help with these decisions




SNS Integrated Control System
  Some EPICS Developments are needed

        Large Array Support
         » Needed for Diagnostics
        Long PV Names
         » We could bump up against the current limit
        Variable String Size
        Multipriority Channel Access
         » Needed for Diagnostics and Machine Protect



        SNS will fund some of these Core developments, but
         we will need help from the community…
