  1. NSRL Control System NSRL Control System Presented byLi, Chuan National Synchrotron Radiation Laboratory

  2. National Synchrotron Radiation Laboratory • Hefei Light Source

  3. Hefei Light Source (HLS): second generation dedicated synchrotron light source • 200MeV electron linac • Beam transport line • 800 MeV electron storage ring

  4. Old control system Problems: • No connection between subsystems • Software function was simple • No database, only parameter backup in some subsystems • Hardware components were out of date and maintenance becomes more and more difficult

  5. Phase II project of NSRL started in April 1999 formally. • Design Philosophy for new control system • Adopting distributed architecture • Applying standard hardware interfaces: Sun workstation, Industrial PC, PLC • Cost-performance should be considered

  6. OPI LAN IOC I/O Equipment • New control system: based on EPICS • Operator Interface, OPI • LAN • Input/Output Controller, IOC Fig. Basic hardware structure of control system based on EPICS

  7. Upgrade process in Phase II Project • May 1999: set up a prototype system • June 2000: the first subsystem（storage ring main magnet power supply control system）was commissioning. • Oct. 2003: the last subsystem（storage ring octupole magnet power supply control system）was commissioning. • Upgrade process after Phase II Project • upgrade EPICS base version to R3.13.10 • Continually add or update subsystem: New transport line magnet power supply control system New wiggler main power supply control system Magnet temperature monitor system Ring Vacuum SIP monitor system ……

  8. Hardware platform • 1 Sun Ultra 1 • 3 Sun Ultra 10 • 1 Sun E250 • 18 PC（Linux，Windows） • A large number of Industrial PC (IPC) • Others: such as PLC, single-chip microcomputer

  9. Software environment: • OPI：Solaris7/8; Red Hat7/9; WindowsXP/2003 • IOC：vxWorks 5.3.1 • Local controller: vxWorks 5.3.1, Windows, etc. • EPICS base: 3.13.10 • Program language: C, SNL, tcl/tk, PHP • EPICS tools: dct, MEDM, sddstoolkit • Database: Oracle 8i, SQL server

  10. Hardware in HLS Control System

  11. Topological structure of the dedicated control LAN

  12. 8 subsystems: • Power supply: • Ring main magnet PS; Ring corrector magnet PS; Ring octupole magnet PS; Skew quadrupole mag. PS • Transport line magnet PS; Linac magnet PS • Klystron focusing coil PS • Injection system pulse PS; Linac modulator pulse PS • Wiggler main PS; Wiggler compensation PS • RF • Vacuum • BPM,PBPM • Interlock • Flag • Temperature • Linac Temperature; RF Cavity Temperature • Magnet Temperature; Water Temperature; Environment Temperature • SoftChannel

  13. 23 OPI • 5 Sun Ultra (Solaris7/8) • 4 PC (Linux7.0/9.0) • 14 PC (WindowsXP/Windows2003 Server) • 25 IOC • IPC (with flash disk diskonchip 2000) • 180Local controller • 56IPC (with flash disk diskonchip 2000) • 16 PLC • Others, 108 • 100M dedicated LAN, 5 switches

  14. Current regulating PS control • Current regulating PS:199 • Ring main mag. PS (12) ; Ring corrector mag. PS (32); Ring octupole mag. PS (1); Skew quadrupole mag. PS(2) • Transport line mag. PS (80); Linac mag. PS (30) • Klystron focusing coil PS(42) • IOC: • IPC with diskonchip 2000 • 8 port serial board (MOXA,C168P) • Local controller: • IPC with diskonchip 2000; • 12/16b ADC/DAC board, Relay/DI board; optical isolation • Communication: • RS232 over fiber; RS422 with optical isolation • point to point

  15. BPM: done by beam measurement group • VXI • LabView + ActiveX • 48 bpm Channels • 6 pbpm in use

  16. The count of local controllers based on IPC↑(Increase) → The reliability of whole control system ↓(Decrease) • Failure Reason: • CPU fan • Memory bank • The communication protocol between IOC and local controller is too simple to deal with all kinds of errors because it is designed by ourselves.

  17. A new kind of PS local controllers based on Agilent34970A Data Acquisition/Switch Unit RS232/GPIB To IOC Agilent34970A Addressing Communication IPC Bus AD DA DI DO

  18. Advantage: • Higher reliability • SCPI Communication Protocol • No CPU Board on IPC BUS • Higher measurement precision • 16 bit AD → 22 bit AD • No need program for local controllers

  19. Software in HLS Control System

  20. Software development for IOC • Record: ～3000 • Record type: Ai, Ao, Bi, Bo, Mbbi, Mbbo, MbbiDirect, MbboDirect, Subroutine, subOut and maio. subOut and maio are new record types we development. • device support/device driver development • Create db using DCT • SNL（State Notation Language）and sequencer

  21. Record statistics

  22. Software of OPI • MEDM : edit and manage most of man-machine interface • Tcl/Tk + SDDS toolkit: complicated control, such as ramping control • Matlab: matrix calculation,such as closed orbit correction • PHP: Web page, such as machine status online

  23. Beam ramping • Ramping table calculation • E-B relation, B-I curve ，I-D curve • C, Tcl/Tk • Rampingcontrol: • No dedicated hardware • Ramping, ramping down, tune ramping

  24. A typical operation mode： • Injection 200MeV electron from linac； • Ramping it to 800MeV； • Tunning lattice，decrease emittance from 160nmrad to 80nmrad； • Compensation Lattice while charge Wiggler Main PS; • Running closed orbit correction.
