  1. Pohang Accelerator Laboratory POSTECH The status of PLS EPICS application EPICS collaboration meeting 2004Dec8 - 10 , 2004 RICOTTI, Tokai, JAPAN Pohang Accelerator Laboratory Kiman Ha, M.Y Oh, J.H Kim, J.M Kim, J.W. Lee, J.C. Yun, J.H Choi hkm@postech.ac.kr EPICS Collaboration Meeting 2004 @ RICOTTI, Tokai, JAPAN

  2. Pohang Accelerator Laboratory POSTECH Outline -Present status of PLS -New project PAL-XFEL -Summary EPICS Collaboration Meeting 2004 @ RICOTTI, Tokai, JAPAN

  3. Pohang Accelerator Laboratory POSTECH Feedback status This has been a big issue at PLS, with epics based control system. BPM, PS, ID’s are necessary elements of the feedback operation • November, Orbit feedback operation started for user service. -Orbit stability with feedback • short term (1 hour) : < 1 m • long term (12 hours) : < 3 m • 22 sets of V and H corrector PS are involved for orbit feedback EPICS Collaboration Meeting 2004 @ RICOTTI, Tokai, JAPAN

  4. Pohang Accelerator Laboratory POSTECH EPICS status • -Most control system upgraded to EPICS • Power Supply • BPM • RF • Modulator • ID control EPICS Collaboration Meeting 2004 @ RICOTTI, Tokai, JAPAN

  5. Pohang Accelerator Laboratory POSTECH Hardware platforms • -VME • MVME5110 – 15 , BPM, Corrector, RF Operation • MVME5500 for RTEMS test -PC Windows • Quad MPS, Beam current, ID -PC Linux • Kicker, Septum - Power MAC G4 • Epics PV monitoring Web Server EPICS Collaboration Meeting 2004 @ RICOTTI, Tokai, JAPAN

  6. Pohang Accelerator Laboratory POSTECH Used epics software toolkit -Matlab CA: Global orbit feedback -Ca : Operator panel, correction utility -MEDM : Operator panel -EDM : Operator panel -Gateway -Web based PV monitoring >mySQL >PHP >GNU plot -Oracle based Web server EPICS Collaboration Meeting 2004 @ RICOTTI, Tokai, JAPAN

  7. More upgrade plan and testing Pohang Accelerator Laboratory POSTECH • -LINUX IOC kernel upgrade 2.6 • RTEMS MVME5500 IOC tested • >Environment ready >BSP(from kate Feng) and example IOC tested at MVME5500 >AsynDriver 4.0 tested E2050B with HP3458 GPIB EPICS Collaboration Meeting 2004 @ RICOTTI, Tokai, JAPAN

  8. Pohang Accelerator Laboratory POSTECH FEL injector Linac Storage Ring fs-FIR FEL-1 FEL-2 FEL-3 PAL-XFEL layout • PAL XFEL Project • Period: 2005-2009 • Budget: 80 M$ • SASE FEL • Energy: 0.7 - 3 GeV • FEL-1: 10~50 nm • FEL-2: 2 ~ 5 nm • FEL-3: 0.1 ~ 0.3 nm EPICS Collaboration Meeting 2004 @ RICOTTI, Tokai, JAPAN

  9. Pohang Accelerator Laboratory POSTECH Status for PAL-XFEL -October, established task force team for XFEL design -Review of construction budget -Review of Beam line -Review of Linac Microwave -Review of Diagnostics -Review of Safety EPICS Collaboration Meeting 2004 @ RICOTTI, Tokai, JAPAN

  10. Pohang Accelerator Laboratory POSTECH XFEL control system status We are collecting FEL control system applications from LCLS, DESY,.. -Timing -Modulator -Power Supply -BPM -Diagnostic EPICS Collaboration Meeting 2004 @ RICOTTI, Tokai, JAPAN

  11. Pohang Accelerator Laboratory POSTECH Summary • - PLS, successfully upgraded to epics based control system • Easily accessible by high level users • Very stable control and feedback -PAL-XFEL project will require highly enhanced hardware and software EPICS Collaboration Meeting 2004 @ RICOTTI, Tokai, JAPAN
