6. Status of the Project Good News Unresolved Issues
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 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

9. Control System Construction is distributed among all Collaborating Laboratories

10. Total Controls Manpower Construction 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 , 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 Database creation
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.
We hope to contribute to EPICS
We look for help and advice from this meeting

17. Create 65-mA H- ion beam Ion Source/LEBT
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
