Control System Progress • • • 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 Daresbury Laboratory Overview of DIAMOND to the European EPICS Meeting at PSI May 2001 Mark Heron

Control System Scope “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. ” Daresbury Laboratory Overview of DIAMOND to the European EPICS Meeting at PSI May 2001 Mark Heron

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

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

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

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

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

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 Daresbury Laboratory Overview of DIAMOND to the European EPICS Meeting at PSI May 2001 Mark Heron

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 RS 232, 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 Daresbury Laboratory Overview of DIAMOND to the European EPICS Meeting at PSI May 2001 Mark Heron

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 Daresbury Laboratory Overview of DIAMOND to the European EPICS Meeting at PSI May 2001 Mark Heron

Relational Database • • • 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 Daresbury Laboratory Overview of DIAMOND to the European EPICS Meeting at PSI May 2001 Mark Heron

Applications Interface • 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 Active.

Application Model Daresbury Laboratory Overview of DIAMOND to the European EPICS Meeting at PSI May 2001 Mark Heron

Industrial Support • • 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 Daresbury Laboratory Overview of DIAMOND to the European EPICS Meeting at PSI May 2001 Mark Heron

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 Daresbury Laboratory Overview of DIAMOND to the European EPICS Meeting at PSI May 2001 Mark Heron

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

Conclusion • • EPICS is not as frightening as led to believe !! • Lots of issues to resolve for DIAMOND control system • We need to consult the EPICS community Confident EPICS will enable EPICS is a very good choice for an accelerator control system 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 Daresbury Laboratory Overview of DIAMOND to the European EPICS Meeting at PSI May 2001 Mark Heron
