EPICS based systems in KEK

• KEKB project
• 3.5GeV(e) x 8GeV(e-), L1034 /cm2/sec
• PF-AR
• 5-6.5 GeV electron ring for SR
• Control system update(JFY2001)
• J-PARC(Japan Proton Accelerator Research
  Complex)
• Under Construction
• 600MeV Linac, 3GeV 50GeV Synchrotron
• http//www.j-parc.jp/

KEKB

• 1999, FallCommissioning started
• 2003, Spring Achieved the design Luminosity
  1034/cm2/sec.
• Many auto changer programs
• Analysis of archived data played important role
  in the machine development.
• Anyone can access these data using uniform way
• She/he needs to know just record(channel) name.
• EPICS makes it EASY

4
PF-AR

• Upgraded from old mini computer based system to
  EPICS based new control system.
• Shares network and host computes with KEKB
  control system.
• 13 IOCs (Force Power Core 6750,PowerPC)
• Inherits CAMAC as a one of field buses.
• LAN GP-IB gateways from Agilent are widely used.
• Linux boxes are used as OPI
• Uses the Channel Archiver for data archiving

5
PF-AR (2)

• Operation Logging etc.
• Web Based information system
• Cybozu Commercial groupware http//cybozu.co.jp/
  
• Zope Open source Web Application server
  programhttp//www.zope.org/
• Future Plan
• Controls of Insertion device using EPICS

6
J-PARC

• Proton(Hadron) accelerator Complex at
  Tokai(JAERI) as a JAERI-KEK joint project.
• 600MeV Linac
• Test operation in KEK site, this year.
• 3GeV Synchrotron
• 50GeV Synchrotron
• Beam Line to the experimental hall

7
J-PARC

• Timing module design was fixed.
• Network based power supply controller board (PLC
  like protocol)
• NetDev a framework for network based PLC and a
  like(?).
• Linux IOC to integrate non-EPICS systems.

8
NetDev

• Framework to support Network based PLC
• Currently supports
• Yokogawa, Mitsubishi, Omron, J-PARC network power
  supply controller
• Easy to extend to support more PLC type product.
• Core development by J-I Odagiri
• Collaboration with RIKEN, Mitsubishi.
• Runs on both VxWorks/IOC and Linux/iocsh
• More detail on Thursday

9
Linux IOC (1)

• Image data from a frame grabber board on Linux
  PC.
• Will use Python/Tk widget to display an image on
  a screen
• Device Support to access RDBMS(postgreSQL or
  MySQL)
• Communicate an existing power supply controls
  through RDB.(Dont ask me why, please)

10
Linux IOC(2)

• Gateway to Facility control system
• Facility control system was updated last summer.
• Control system is based on proprietary
  PLC(Hitachi)
• Gateway is introduced to monitor parameters, such
  as cooling water temperature, air temperature in
  a tunnel.
• Linux IOC with EPICS R3.14
• Read only device support is developed by Hitachi
• Single thread receives a set of data from the
  facility control and store the data into iocsh
  memory space
• It also post EPICS event in iocsh
• Each record updates its value

11
EPICS collaboration in ASIA

• China
• Supported by China-Japan core university program
• EPICS seminar will be held somewhere in China
  under the collaboration with SSRC, in next
  spring.
• IHEP,Beijing decided to use EPICS for BEPCII
  controls.
• PLS, Korea
• Will introduce SAD and EPICS into their control
  system.

12
Remote operation

• GAN workshop -gt ICFA working group
• Collaboratory working group in KEK
• Security based on PKI/PMI (CCAcc)
• GRID
• Remote operation of equipments (MSL/KEK)
• Currently uses Windows XP based applications

13
EPICS traversal group in KEK

• EPICS traversal group is formed to support EPICS
  environment for these Accelerators
• Only three core members
• N. Yamamoto
• J-I. Odagiri
• N. Kamikubota
• All members of the control groups for three
  accelerators are also member of this group.

Simple Automation
We need to adjust Tunes of the KEKB rings
according to the Stored beam current.
