Data Archiving in J-PARC MR control system
6
From “DATA ARCHIVE SYSTEM FOR J-PARC MAIN RING” by N. Kamikubota et al.,Proceedings of IPAC’10, Kyoto, Japan
Overview of J-PARC MR data archive system:“cadump” is a program storing snapshot data,including waveform, into disk system. ROOT and SAD data formats are supported. It also use data compression, after Feb. 2010.

Control Systems at KEK/Tsukuba (1)SuperKEKB
Will inherit resources from KEKB (and TRISTAN)Partial budget for positron was approved (?)
Linac (electron/positron)Inject beam to (Super)KEKB, PF, PF-AR
Pulse-to-pulse beam modulation
PF (Photon Factory)Moved to EPICS environment
Mainly with Linux-VME
PF-AR (Photon Factory Advanced Ring)Mostly the same environment as KEKB
Many CAMAC installations

Control Systems at KEK/Tsukuba (2)ATF (Accelerator Test Facility)
Vista Controls environment with CAMACLinux and socket environment with some EPICS
devices
STF (Superconducting RF Test Facility)Test facility for ILCEPICS with Linux, ATCA test, PLC, …
cERL (Compact ERL)Being built for ERL development May share the resources with other accelerators
Sharing resources as much as possible8

Accelerator ControlsVME + Unix (~1995)
Standard EPICS configurationWith many third layer field networks
Every controller on network (1993~1997)Single layer in physical, two layer logical
Every controller with EPICS IOC (2005~)Channel Access everywhereFor longer term maintenance

Embedded IOC in Yokogawa’s PLCMore than 150 PLCs were employed at
LinacAll through TCP/IP network since 1993Successful to reduce resource consumption
Now Linux CPU is available (2008~)533MHz PPC, 128MB RAM, 2xEthernet, USBUtilize realtime feature of Kernel 2.6 (J.
Odagiri et al)EPICS PV response time <150sec (incl. module
delay)
Ladder sequence CPU can coexistVariable sharing possible

Logics are confined in PLC, and management is easier
SuperKEKB Plan (3)Interviews to each device groups
Planning to have monthly meeting and trainingTo collect user requirements
Partially successful for old hardware replacements
Not yet effective for new functionalitiesWhether both sides do not have experiences
ex. Global orbit feedbackWe don’t need to stabilize the orbit other than the collision
point
Monitor group is basically responsible for thisUnder development with several candidatesBut they still need some data path

Simultaneous InjectionSuperKEKB injections with shorter lifetimePF top-up injection for higher quality experiments
Enjoyed Hardware and Software Installation One by oneReduced the Beam Switch Time from 10-120 seconds to 20msBeam currents are kept within 1mA (~0.05% for KEKB), 0.05mA (~0.01%, PF)
Much more complicated with bucket selections at damping ring and main ringShould add PF-AR as well (4rings! with different beams)
