  6. 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…)???

  7. An aside…

  8. We plan a system fullyintegrated 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

  9. Control System Construction is distributed among all Collaborating Laboratories ICWG include JLAB 1.3 1.4 1.5 1.6 1.7 1.8 1.9 Cryo Front End Linac Ring Target Instruments Facilities Controls (JLAB, ORNL) (LBNL) (LANL) (BNL) (ORNL) (ORNL, ANL) (ORNL, CM) 1.9.3 1.9.4 1.9.5 1.9.6 1.9.7 1.9.8 1.9.10 1.9.9 Front End Linac Ring Target Instrument Facilities Cryo Personnel Controls Controls Controls Controls Controls Controls Controls Safety 1.9.2 “Global” Controls: (Network, Timing, Protection, Control Room, Labs, Applications, System Software) 1.9.1 Integration & Management

  10. Total Controls ManpowerConstruction and Operations

  11. Where we are now • Controls Group Staff of 10 here at ORNL • EPICS Systems running Target Test Facility here and Front End Systems at Berkeley • Application Development Environment here at ORNL • Distributed CVS – accessible by all the partners • Prototypical Environment running in lab here • MVME 2100 PPC, EPICS 3.13.3, Tornado II, DM2K • ControlLogix PLC • ControlNet over EtherNet Driver

  12. The SNS Control Room

  13. 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…

  14. … 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

  15. 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…

  16. Summary • Jobs available • Many issues the EPICS Community can help us with. • Jobs available • We hope to contribute to EPICS • Jobs available • We look for help and advice from this meeting • Jobs available

  17. Front End – A Highly Complex System with Several Major Subsystems and Critical Functions The Front End has relationships with all systems: rf, high voltage, diagnostics, alignment, controls, magnets, power supplies, pulsed power, physics, vacuum, Cesium, radiation. Create 65-mA H- ion beam Ion Source/LEBT Accelerate beam to 2.5 MeV RFQ Chop beam into mini-pulses LEBT/MEBT Match 52-mA beam into DTL MEBT
