2. Where is Saskatoon?

3. Why Saskatoon? 1964 Saskatchewan Accelerator Lab (SAL) was established for chemistry and nuclear physics research. Saskatoon was chosen for the CLS due to existing complement of staff and facilities

4. What are the CLS Objectives? 170.88 m circumference 2.9 GeV DBA lattice with 12-fold period Nominal Tune: x = 10.22 y = 3.26 E loss per turn: > 0.876 MeV Bend magnet radiation: c = 1.6 Å E c = 7.6 keV  x = 18.1 nmrad Damping times:  x = 2.4 ms,  y = 3.8 ms,  E = 2.7 ms ~10 mm bunch length

12. Safety Critical Software Applications: –lockup system (ACIS) –Oxygen monitoring –BMIT human studies (under development) IEC 61508 – SIL 3 based system Siemens S7/400 F Redundant Second Chain Fail-safe design Independent Verification

13. Agenda The CLS Facility Quality Assurance Program System Engineering Approach Control and Instrumentation Design

14. System design based on highly distributed control. Extensive use of single board computers (originally used in SAL). Target lifetime of 15+ years. Data communication over Ethernet when possible. System must be user-friendly. The accelerator and beamline systems must be maintainable by a small team. Reliability and availability of beam are critical to the success of the facility. Building an open source control system was not the initial goal, it was the outcome. Accelerator complex must be complete by Dec. 2003 and the first phase of beamlines by Dec. 2004. The project must come in on budget. Control System Design Principles

15. Distributed Control Systems The options: (1) EPICS or (2) Isagraph/Virgo. EPICS was selected, since it had: –large built up accelerator and beamline user community; –availability of suitable drivers and utilities; –credibility with the CLS user community; and –good design. EPICS Extensions selected include: –EDM, –Accelerator Toolbox, –Gateway and –Data Archiver. EPICS extensions that were locally developed: –assortment of drivers, –IOC Auto-Save-Restore, –simple beamline scanning program, and –SQL Alarm Management Database.

16. The options: (1) Sun or (2) Linux. Linux was selected, since it had: –better hardware availability, and –fairly equivalent reliability levels. EPICS Extensions selected include: –EDM, –Array Display Tool, –StripTool, and –Knob Manager. We are now starting to deploy touch screens running Linux/EDM. The Operator Interface

18. Related displays: links to other EDM screens

19. Implementation A group status PV is created to indicate the collective status of a group of components in a sub- system. Eg. PV LTB1:IOP:status gives the collective status for all the ion pumps in the LTB The group status PV monitors all individual PVs in this group and calculate the group status. Different algorithms are used for different types of PVs. Eg. The most common algorithm finds out the highest alarm level in all the individual PVs and pass it to the group PV.

20. Linac Screen

21. Design – LINAC Master Display

22. Process Screens Some screens are done in Visio or AutoCAD then imported into EDM

23. The Options: (1) RTEMS and (2) VxWorks. RTEMS was selected, since it had: –good experience from SAL, –additional flexibility with single board computers, and –high level of reliability. IOCs are CLS/SIL embedded controllers (approx 150) based on the MC68360 25 MHz. Processor. Pros and Cons: –No dynamically loaded libraries; must be linked prior to download. –Large number of IOCs (separation of function but more points of failure) Note: EROCS now replaced with MOXA Linux computers. Selecting a Real-time OS

24. Moxa Transitioning from SAL single-board- computers to MOXA based IOC Linux based EPICS with the asyn driver and older CLS serial drivers Used extensively for RS-232/422/485

25. Using VME hardware connected to a Linux PC. SIS1100 PCI card fiber optic link SIS3100 VME module Maps VME backplane to IOC memory. Advantages: –PC can be physically separated from VME crate. –More than one VME crate per PC. –Multiple applications can access the same crate. –High throughput 25 to 80 Mbytes/sec block transfer. Work ongoing on RTEMS support. VME

26. The options: (1) Matlab, (2) SciLab, or (3) root. Matlab was selected primarily because of the availability of the accelerator toolbox and staff experience. Matlab is commercial, the accelerator toolbox is open source. Software originates from ALS and SPEAR III. Augmented with other CLS specific utilities. Also being used as a commissioning tool for beamlines. Special care is required to maintain consistency with other parts of the control system. Online scripting environment

27. Provides fiber optic signal distribution of triggers. VXI based hardware IOC running EPICS on RTEMS. Operator Interface implemented using Glade. Glade was selected for the table and file handling capabilities. Timing System

28. Single board computers (EPICS/RTEMS) used for: –stepper motors, –power supply control, –vacuum equipment monitoring, –radiation monitors, and –other RS-232 devices. PLC hardware/software used for machine protection. Industrial PCs with VME used for diagnostics. Linux servers used for high- level control, network services and EPICS/PLC interface. MOXA RS-232 Computers Implementation Strategy

29. Beamline Controls are based on the same software and hardware as the accelerator systems. Each beamline is on a separate virtual network. The EPICS Gateway provides links between the different networks. Matlab is used for scripting. Beamlines
