X-rays interact with electrons.

♦ X-rays see high-Z atoms.Neutrons interact with nuclei.

♦ Neutrons see low-Z atoms.

X rays (left) and

Neutrons (right)

Example of Study◆ Neutron Science

Need Different Kinds of Probes to Study

◆ Nuclear Physics with Kaon, etc◆ Nutrino Physics (Kamiokande) ◆ Nuclear Transmutation

Control Systems at KEK◆ KEKB Ring -- e-/e+ Collider, EPICS, 1998~

Establishing Luminosity RecordsControls of Utility System will be Based on EPICS

◆ PF-AR -- e- Light Source, EPICS, 2001~ (1987~)EPICS Conversion Went Well(+Channel Archiver, Delphi, ...)

◆ JAERI-KEK Joint Project -- EPICS, 2006~Just Started ...

◆ e-/e+ Linac -- RPC, PF -- DataChannel,PS -- Windows +VME/MAP, ATF -- V-System

Their Own Control Systems

◆ EPICS Traversal GroupStandardization of EPICS Environment, etc

◆ SAD + Python, etc.Application/GUI (for Rings)

Linac: SAD + ? (with Space-charge)

◆ Sub-systemsDesigned mainly by Equipment GroupsSub-contract (with Interface to EPICS?)Detachable Sub-systems, preferable?

◆ IP/Network based ControllersNo Specific Local Field Network, but only EthernetSuccess at e+/e— Linac (~250 Controllers)

Network Based Controller (NC) under EPICS (1)◆ 5 Components

◆ NC (such as PLC) : Mostly Designedby Experts, Carrys Local Logics

◆ EPICS IOC : Carrys Logicsbetween Several Devices

◆ EPICS OPI : Normal OPIDo not See Existence of NCs

◆ Management Station : Software Downloadingand Monitoring

◆ Network : Switch TechnologyPhysical and Logical Views are Different

Network Based Controllers◆ PLC :

Yokogawa’s FA-M3 (Factory ACE)Maintenance Capability over Ethernet/IP

Evaluating Basic EPICS Device Support

◆ Measurement Station :Yokogawa’s WE7000 for Now

100ks/s, 100Ms/s, (1Gs/s,) 10MHz FG.Improving Device Support outsourced to Mitsubishi.Co.

Simple Function: ~1ms

◆ DTL-Q Power Supply :Designed Dedicated Plug-in Ethernet Controller

Mostly the Same Protocol as PLCProduced by Nichicon Co./Internix Co.
