  1. KEK: status Noboru Yamamoto KEK, EPICS group/KEKB control at EPICS Asia 2004

  2. KEK Accelerators and its controls KEKB JPARC EPICS PS LINAC PF-AR PF

  3. KEKB/PF-AR Based on EPICS Share infrastructure for contorls Network Switched FDDI Backbone/Ethenet field network Moving toward GbE backbone/Fieldnetwork Optical Fibre backbone Host computers Alpha/True 64 PA-RISC/HP-UX Linux Mac OS X(Darwin) SAD/Tk, Python/Tk + CA library

  4. EPICS related development NetDev Framework to suppor network based devices EmbeddedEPICS EPICS on iTRON/SH4 EPICS on RTEMS/SH4, x86 MiniEPICS 1 CD EPICS installation package EPICS system on Knoppix Web client for Channel Archiver 2 Immitate CGIExport for Chan. Arch. 1 Secure CA Study possibility of CA over secure network

  5. MCU Made by Nichizou MCU running μITRON SH4 (SH7751R-200 MHz) FLASH ROM 16MB SDRAM 64MB

  6. System development/improvement J-PARC 60MeV LINAC was commissioned with EPICS based control system. Setting up EPICS 3.14 envrionment. Channe Archiver performance test IOC network performance evaluation. Force Pcore6750 had shown poor network perforamance. -->New BSP solved this problem. Stable opeartion under Fast Ethenet Stil show poor performance for file transfer. Preliminary test in KEKB control system shows that Force Pcore695 has reasonalbe network performance. 11MByte/sec with GbE to copy file from NFS server

  7. System development/improvement KEKB/PF-AR Improvement fro KEKBLogger system. Data chache on users directory Distributed retrieve engine. Share files over NFS Each hosts run data retreival progam Data retreival program (kblogrd) runs both big- -and little- endian machines. Educate operators for development to
