Goals at J-PARC
Need to have high-powerproton beams
MW-class proton accelerator (current frontier is about 0.1 MW)

Phase 1 and Phase 2
– Phase 1 + Phase 2 = 1,890 Oku Yen (= $1.89 billions if $1 = 100 Yen).
– Phase 1 = 1,527 Oku Yen (= $1.5 billions) for 〜 8 years.– JAEA: 860 Oku Yen (56%), KEK: 667 Oku Yen (44%).

J-PARC Control System
Protect from Radiation– Intelligent Beam Control
• Keep stability of electro-magnetic field• Keep minimum beam loss• Predict beam behavior
• System identification and definition of response function
• By link of operation and simulation• By link of operation and database
Integrated Operation Environment– Effective use of software technology
In the process of developing

Function of Safety
Radiation Measurement System– Legal management of the area boundary
Personnel Protection System (PPS)– Make and keep the boundary condition of closed
space which is allowed existence of the beam– Stop the beam when the condition breaks
Machine Protection System (MPS)– Protect machine from high power beam
bombardment– Stop the beam when something is wrong
Computer Control System– Automatic correction, FB, FF– Suggest the optimum parameters

NETWORK
Standard protocol for redundancy can not make the performance that no connection loss when the pass way is switched.
We selected the protocol of the vender dependence.
For ease of physical fiber topology, we use the combination of ESRP and EAPS.

NETWORK
ESRP test by single fault ESRP test by double fault
No matter appears when the power of switch is down, or when fiber is disconnected.
When the route revives, the connection doesn't become interrupted.

Time of route change < 1.2sec(including route reviving. Any TCP connection is not closed at this route change.)

TIMING SYSTEM
Single Shot is generated for the initial commissioning– Effective to reduce activation
Type code means operation mode and beam course
Individual delay trimming can be done without stopping the beam– Two way of changing delay time.
Delay time changing of selected channels can be done simultaneously
23
Data Acquisition
On the EPICS, fundamental data can be acquired.
High power beam handling required the traceable data of each shot, selected shot, event occurred shot.
Trade off of data size (resolution, repetition) with transport– Separate storing data and gathering data
Concept of Selecting Data– We need the data at the event.
• (around the event, before and after)

SUMMARY
Infrastructure of the J-PARC control system was completed.– Covered area will be extended to MR, MLF next year.
Fundamental function of PPS, MPS, TS and Data Acquisition are successfully established for the 1st stage of commissioning.
High Level Application is developed on the Integrated Operation Environment– IOE is written in java, and it’s API can merge several
simulation and other IOE tools
