EPICS in KEK Noboru Yamamoto at EPICS collaboration
EPICS in KEK Noboru Yamamoto at EPICS collaboration meeting June 18, 2003 2/28/2021 1
EPICS based systems in KEK l KEKB project: – 3. 5 Ge. V(e+) x 8 Ge. V(e-), L=10^34 /cm^2/sec l PF-AR: – 5 -6. 5 Ge. V electron ring for SR – Control system update(JFY 2001) l J-PARC(Japan Proton Accelerator Research Complex): – Under Construction – 600 Me. V Linac, 3 Ge. V & 50 Ge. V Synchrotron – http: //www. j-parc. jp/ 2/28/2021 2
KEKB l l l 1999, Fall: Commissioning started 2003, Spring: Achieved the design Luminosity 10^34/cm^2/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 2/28/2021 3
PF-AR l 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, Power. PC) – 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 2/28/2021 4
PF-AR (2) l Operation Logging etc. – Web Based information system • Cybozu : Commercial groupware http: //cybozu. co. jp/ • Zope : Open source Web Application server program http: //www. zope. org/ l Future Plan – Controls of Insertion device using EPICS 2/28/2021 5
J-PARC l Proton(Hadron) accelerator Complex at Tokai(JAERI) as a JAERI-KEK joint project. – 600 Me. V Linac • Test operation in KEK site, this year. – 3 Ge. V Synchrotron – 50 Ge. V Synchrotron – Beam Line to the experimental hall 2/28/2021 6
J-PARC l l Timing module design was fixed. Network based power supply controller board (PLC like protocol) Net. Dev: a framework for network based PLC and a like(↑). Linux IOC to integrate non-EPICS systems. 2/28/2021 7
Net. Dev l l Framework to support Network based PLC Currently supports: – Yokogawa, Mitsubishi, Omron, J-PARC network power supply controller l l l Easy to extend to support more PLC type product. Core development by J-I Odagiri Collaboration with RIKEN, Mitsubishi. Runs on both Vx. Works/IOC and Linux/iocsh More detail on Thursday 2/28/2021 8
Linux IOC (1) l Image data from a frame grabber board on Linux PC. – Will use Python/Tk widget to display an image on a screen� l Device Support to access RDBMS(postgre. SQL or My. SQL) – Communicate an existing power supply controls through RDB. (Don’t ask me why, please) 2/28/2021 9
Linux IOC(2) l 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 R 3. 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 2/28/2021 10
EPICS collaboration in ASIA l 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. l PLS, Korea – Will introduce SAD and EPICS into their control system. 2/28/2021 11
Remote operation l l GAN workshop -> ICFA working group Collaboratory working group in KEK – Security based on PKI/PMI (CC&Acc) – GRID – Remote operation of equipments (MSL/KEK) • Currently uses Windows XP based applications 2/28/2021 12
EPICS traversal group in KEK l l EPICS traversal group is formed to support EPICS environment for these Accelerators Only three core members: – N. Yamamoto – J-I. Odagiri – N. Kamikubota l All members of the control groups for three accelerators are also member of this group. 2/28/2021 13
