Cyclotrons and FFAGS: From Nishina’s Pioneering Work to RI-Beam Factory Michael Craddock (UBC&TRIUMF)
The first cyclotron to operate outside the USA was built by Professor Nishina's group at
RIKEN (1935-7). It was quickly followed by three more Japanese machines, establishing atradition that has produced many important research cyclotrons, culminating with the world's
most powerful - the superconducting SRC at the RIKEN RIBF.
Japanese scientists have also been in the forefront of the development of Fixed-Field
Alternating-Gradient (FFAG) accelerators - from the first suggestion by Tihiro Ohkawa in
1953 to Yoshiharu Mori's construction of the first proton FFAG in 2000.

From TRISTAN to B-FACTORY
TRISTAN(1986-1995) is an electron-positron collider for top quark search. The center of mass
collision energy was 50-64 GeV, then highest in the world. To attain the required accelerator
performance, intensive innovative R&D effort had to be made in such technologies as
superconducting RF and magnet, high power RF components, vacuum, instrumentation, etc.
B-factory, KEKB is an asymmetric energy (8 GeV + 3.5 GeV) electron-positron collider for
observation of CP violation in B-meson decays. The facility was constructed in 1998 bymaximally utilizing the TRISTAN resources, and has achieved the world highest luminosity of
2.1 x 1034 /cm2/s. In 2001 the Belle experimental group successfully observed large CP violationin B-meson decays, which eventually lead to Nobel Prize for Kobayashi & Maskawa in 2008.

Developments of SR in Japan

Synchrotron radiation (SR) facilities and researches in Japan are reviewed. Started in theparasitic use of the electron synchrotron st the institute for nuclear science of the university ofTokyo, the SR community constructed SOR ring, Photon Factory, and SPring-8 incollaboration with the accelerator community. The latest development is the x-ray free electron
laser facility which is nominated as one of the 5 key technologies of national importance.

From KEK-PS to J-PARC

The user experiments of J-PARC have just started. The J-PARC, which stands for Japan Proton
Accelerator Research Complex, comprises a 400-MeV linac (at present 180 MeV, being upgraded),a 3-GeV Rapid-Cycling Synchrotron (RCS), and a 50-GeV Main Ring (MR), which is now in
operation at 30 GeV. The RCS will provide the muon-production target and the spallation-neutron
production target with a beam power of 1 MW (at present 120 kW) at a repetition rate of 25 Hz.
The muons and neutrons thus generated will be used for materials science, life science and others,
including industrial applications. The beam fast extracted from the MR will generate neutrinos tobe sent to the Super KAMIOKANDE detector located 300-km west. The slowly extracted beam
will generate Kaons for Hypernuclei experements, Kaon rare decay experiments and so forth. This
unique accelerator scheme and its usage scheme originate from those of KEK-PS. It can be said thatthe J-PARC is an upgraded version of KEK-PS in both the beam energy and beam power. It will bedetailed how the world-class machine of J-PARC has developed from KEK-PS.

Accelerator Developments for Cancer Therapy

Treatments of cancers with charged particle beams are one of the most fruitful applications ofhigh energy accelerators. Japan has become world leader in this field after completion of thededicated heavy ion accelerator, HIMAC. Brief history of the accelerator developments will
be presented.
More than 5,000 patients are treated with carbon ions from “HIMAC” at National Instituteof Radiological Sciences since 1994. Clinical data of the cancer treatments show excellent
results especially against photon-resistant cancers.

Status of ILC and the Role of Japan in Developing the ILC

The ILC design brings together the needs of the world's particle physicists to extend theirreach beyond LHC and the capabilities of the accelerator community to deploy
superconducting RF technology for this purpose. In this talk we will describe the state of theart of the technology needed to build a high luminosity linear collider and show the global
basis for the technology. The latter is a necessary component for the realization of a strongly
multi-lateral international science project. To this end, the ILC Global Design Effort, (GDE),
was established in 2005. To maintain adequate inter-regional balance, the GDE is not hosted
by any single institution and includes representation from each interested institution.
Japanese scientists and institutions have enthusiastically supported this scheme from its
beginning and have had a significant role in its development.
