KEK Roadmap• KEK established its ﬁrst Roadmap (5year plan, 2009‐2013)
in 2008. We have been pursuing realizaQon of research
projects according to this roadmap.
• In April, 2012, we started the update process of the KEK
roadmap in the KEK Research Steering CommiAee.
• This is a boAom‐up process since KEK is an Inter‐University
Research InsQtute CorporaQon. We took into account
inputs from relevant science communiQes: High Energy
Physics, Nuclear Physics, Synchrotron radiaQon research,Neutron science, Muon science.
• The ﬁnal dra[ from the commiAee is now available
hAp://kds.kek.jp/conferenceDisplay.py?confId=11728• The new roadmap “KEK Roadmap 2013” is open to publica[er consulQng the KEK roadmap review commiAee held inApril 2013.

New KEK Roadmap (ﬁnal dra[)
1. Preamble
2. Long‐Term Prospects and KEK’s Role for Each Research Area
2.1 ParQcles and Nuclear Physics
2.2 Materials and Life Science
2.3 Development of ParQcle Accelerators and Related Technologies at KEK
2.4 Development of Detector‐Related Technologies at KEK2.5 KEK as a Center for InternaQonal CooperaQon, Human Resource
Development, and Social ContribuQon
3. Strategy for Next Five Years (2014‐2018)
4. Summary• We try to make it clear that in what stage each project should be for the next ﬁveyears (2014‐2018) .
• Timely realizaQon of the programs requires execuQon plans, taking account ofdevelopment of relevant science and technologies as well as the availability statusof human and ﬁnancial resources.
5Outline of the Strategy for Next Five Years• Japan Proton Accelerator Research Complex (J‐PARC)• SuperKEKB/Belle II• Large Hadron Collider (LHC)/ATLAS• InternaQonal Linear Collider (ILC)• Photon Science (Synchrotron RadiaQon Research)• New development of accelerator and detector technologies
6J‐PARC (1)At the neutrino facility, a signiﬁcant improvement in the measurement precision of
the T2K experiment will be pursued. In addiQon, new research plans will be
developed for the next generaQon of long‐baseline neutrino oscillaQon
experiments, while relevant preparatory studies are pushed forward in parallel.

J‐PARC (2)In research acQviQes at the Hadron Experimental Facility, experiments at the present
and new primary proton beam lines will be steadily advanced, while addiQonal eﬀorts
will be made toward future extension of the facility.

J‐PARC (3)In the neutron program, the high‐priority task is to meet the iniQal performance goal ofthe pulsed neutron experimental facility; this will require further development,
construcQon, and improvement so as to realize great strides in material and life science.
In the muon program, the muon beam lines will be completed and conQnuouslyimproved. This will support research in material and life science through sophisQcatedand creaQve muon spin rotaQon, relaxaQon, and resonance (µSR) experiments, a wide
range of applied research, and research in fundamental physics.
NeutronMuon9J‐PARC (4)Regarding the program for improving J‐PARC’s accelerator systems, a high‐priority
item is to rapidly meet the design beam intensity goal, to be supplemented soon
therea[er with preparaQon for the next‐stage upgrade plans for the facility, which will
enable a major increase in the beam intensity.

10SuperKEKB/Belle II
The goal at SuperKEKB/Belle II is to complete the construcQon of theaccelerator and detector faciliQes, and then to achieve the design luminosity
performance on schedule and to iniQate in‐depth exploraQon of new physics.

LHC/ATLAS
The main agenda at LHC/ATLAS is to conQnually parQcipate in the experiment and to
take a proacQve iniQaQve in upgrade programs within the internaQonal collaboraQon at
both the accelerator and detector faciliQes.

12

ILC
KEK will play a central role in creaQng an internaQonal preparatory group andwill lead the eﬀort on advanced R&D, the engineering design of the apparatus
and facility, and the organizaQonal design toward groundbreaking for the linear
collider project to be hosted in Japan, within the framework of a global
collaboraQon.

Japanese AssociaQon of High Energy Physicists (JAHEP) published the ﬁnal
report on Future Projects of High Energy Physics in March 2012.
Discovery of a Higgs‐like parQcle at LHC was announced in July 2012
JAHEP published “A Proposal for a Phased ExecuQon of the InternaQonal
Collider Project” in October 2012.

Photon Science (Synchrotron RadiaQon Research)
KEK will conQnue to advance photon science by upgrading the Photon Factory (PF)and Photon Factory Advanced Ring (PF‐AR) to improve their performance andeﬃciency. At the same Qme, KEK will construct and then operate the compact energy
recovery linac (c‐ERL) and will demonstrate the key technologies required for the ERL.
By proving the potenQal of the ERL as a new accelerator to open new scienQﬁcfronQers, KEK will work toward construcQon of a 3 GeV ERL facility. In addiQon, KEKwill conQnue to play a leading role in the development of synchrotron radiaQon (SR)research in Japan.

New development of accelerator anddetector technologies
KEK will contribute its expert knowledge and technical capabiliQes with respect
to parQcle accelerators and detectors to collaboraQon with scienQsts fromresearch ﬁelds of overlapping interest and to numerous industrial and medical
applicaQons for the beneﬁt of society. KEK will also promote research that has
the potenQal to signiﬁcantly expand accelerator and detector technologies in
the long term.
