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)???

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

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

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.
