  11. Technical Challenges • Super Conducting RF • Endorsed by TAC • Issues of cavity phase stability • Cryogenics refrigeration plant 1kW at 4.2K • Top Up Injection • Recommend by TAC, but not for day 1 • Booster Stability >> Power supply and control • Injection into specific bunches >> Timing System • Radiation Monitoring >> Integrated Loss • Orbit Stability • Sub Micron Feed Back Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  12. 1999 Evaluated options for a control system tool kit TANGO, Commercial, SRS control system and EPICS 1999 EPICS chosen as control system tool kit 2000 July Budget costing prepared and work package planned 2000 Nov Start of Design Phase 2000 Nov Two staff on EPICS training at LANL 2001 Mar Test stand constructed and operational Base 3.13 2001 April Defined Scope and Requirements of Control system 2001 May Recruitment and training new staff 2001 June 5 Staff on control system 2001 July Evaluation of interfaces preparation of specifications and design report Control System Progress Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  13. “The DIAMOND control system will be a site wide monitoring and control system for the accelerators, beamlines and conventional facilities. The control system will extend from the interface of the equipment being controlled through to the operator. It will include all hardware and software between these bounds: computer systems, networking, hardware interfaces and programmable logic controllers. “ “The control system will not include any control or data acquisition for the experimental stations. It further will not include the personnel protection system, which is a separate system that will be monitored by the control system.” Control System Scope Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  14. Consoles Networking Equipment Interface Protection and Interlocking Timing and Event generation and distribution Wideband (RF) and Analogue Mux systems Control Systems Includes Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  15. Initial Assessment of Equipment * Steering Windings ** Vac for SR and 24 Front Ends *** Transverse FB, Timing , Mux and Conventional services Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  16. Initial Assessment of IOCs * LL RF, Cavites, Amplifiers, PSUs and Cryo plant ** Linac, Booster and Tx Paths Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  17. Summary of Interface Requirements • Total Devices to Control 3781 • Total Number of IOCs 176 • Devices per IOCs approx. 22 • Likely number of PVs 100,000 ???? Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  18. Number of Interfaces • From the Assessment of Equipment the number of particular interfaces is derived • Analogue 1677 • Digital 1111 • VME back plane 73 • Video 8 • GPIB 2 • Serial 2116 • System Integration 8 • This is NOT necessarily channels but interfaces Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  19. EPICS Test Stand • IOC MVME167 • Sun Ultra 10 Solaris • EPICS Base 3.13 • Tornado II • CapFast • PC P3 800MHx Linux Red Hat 6.2 • Epics Extensions • Base 3.14 Alpha 2 Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  20. Immediate Tasks • Training of Staff on EPICS • “Understand” IOC Databases !?!?!?!? • Evaluate EPICS Device support • DIO,AIO, Serial, GPIB, Ethernet • Evaluate existing Driver support • Produce list of supported instruments • Identify areas where development is necessary Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  21. Serial Interfaces • Need to support Serial Interfaces to equipment • Advantages are • Increased functionality per connection • Minimises calibration errors from Control System ADCs • Widely accepted use of RS232,422 etc • Integration of systems • Faster commissioning • Disadvantages are • High processor load • Development to support vendor protocols • Also need hardwire analogue for fast logging and digital for Interlocks Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  22. Equipment Protection Policy • The Control System will manage protection of equipment where required. • Give consistency of behaviour. • Three levels of protection determined by assessment of damage/cost caused by failure • High Integrity : provided in hardware • Routine Interlocking : provided by PLCs • Prudent Operational Limits : provided by IOC DBs Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  23. DIAMOND Control System MUST have a relational database Contain as Minimum the IOC DBs, Device names, and ??? Review other EPICS uses of RDB from June 2001 BESSY II, SLS, SNS Define tools and processes for producing IOC DBs and importing / exporting data to and from RDB Relational Database Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  24. Need to integrate seamlessly other sources of information at the application level RDB, Acc model and ???? CDev provides one solution Low overhead Allows retention of core Epics extensions medm etc Want support for Win API most likely through ActiveX Applications Interface Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  25. Application Model Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  26. Can we buy EPICS ready systems from industry? SLS Linac from Accel SLS RF from Thomcast Power supplies ??? BPM diagnostics from Instrumentation Technologies Support for beam position feed back system EPICS support from Observatory Sciences Ltd in UK VME manufacturers already offer support in the form of EPICS drivers Hytec in the UK Industrial Support Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  27. A Model For Procurement • Contract out build, install and commission of large parts of the Control System, by defined packages of work • Consoles and Servers • Network • Equipment Interface per technical area • Magnet PSU, RF, Diagnostics, Vacuum, Linac, ….. • Provide integration at the IOC level • CLRC then has responsibility for overall integration • Effective way to manage risk in procuring the control system Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  28. Partition Control System Consoles & Servers Network IOCs Main PSUs Steering PSUs RF Vac Diag. IDs Conventional Facilities Overview of DIAMOND to the European EPICS Meeting at PSI May 2001

  29. EPICS is not as frightening as led to believe !! EPICS is a very good choice for an accelerator control system Lots of issues to resolve for DIAMOND control system We need to consult the EPICS community Confident EPICS will enable The Control System to be available from day one of accelerator operation The Control System to support commissioning and operation of the accelerators not hinder Conclusion Overview of DIAMOND to the European EPICS Meeting at PSI May 2001
