KEK Roadmap• KEK established the ﬁrst research Roadmap (5‐year plan) in 2008.
• The update of the KEK roadmap started in 2011 and completed inMay, 2013.
• This has been a boAom‐up process since KEK is an Inter‐
University Research InsRtute CorporaRon. We took into account
inputs from relevant science communiRes: HEP, Nuclear physics,
Synchrotron radiaRon research, Neutron science, Muon science.
• In October 2012, aYer the discovery of Higgs‐like parRcle at theLHC, the Japanese HEP community proposed a phased execuRonof ILC hosted in Japan as a global project.
• KEK roadmap 2013 is available together with the report of theroadmap review commiAee at the following page.

J‐PARC

Reach the ini*al goal of each scien*ﬁc areaand prepare for J‐PARC science in 2020’s

At the neutrino facility, a signiﬁcant improvement in the measurement precision of theT2K experiment will be pursued. In addiRon, new research plans will be developed forthe next generaRon of long‐baseline neutrino oscillaRon experiments, while relevant
preparatory studies are pushed forward in parallel.
In research acRviRes at the Hadron Experimental Facility, experiments at the present andnew primary proton beam lines will be steadily advanced, while addiRonal eﬀorts will bemade toward future extension of the facility.
In the neutron program, the high‐priority task is to meet the iniRal performance goal of
the pulsed neutron experimental facility; this will require further development,construcRon, 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 conRnuouslyimproved. This will support research in material and life science through sophisRcatedand creaRve muon spin rotaRon, relaxaRon, and resonance (µSR) experiments, a wide
range of applied research, and research in fundamental physics.
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 thereaYer
with preparaRon for the next‐stage upgrade plans for the facility, which will enable amajor increase in the beam intensity.

5Recent developments at J‐PARC• ConstrucRon of the high momentum
beam line and the COMET phase Iexperiment started in FY 2012 at theHadron Experimental Facility.
• User operaRons at Materials and Life
Science Facility started in February,
2014 for the ﬁrst Rme aYer the J‐PARC
Hadron Hall radiaRon leak on May, 23,
2013.
• In order to discuss future neutrino programs in Japan, aseries of workshops on Next GeneraRon Accelerator‐
based Neutrino Experiment has been iniRated.
6SuperKEKB/Belle II
The goal at SuperKEKB/Belle II is to complete the construcRon of theaccelerator and detector faciliRes, and then to achieve the designluminosity performance on schedule and to iniRate in‐depth
exploraRon of new physics.

LHC/ATLAS
The main agenda at LHC/ATLAS is to conRnually parRcipate in theexperiment and to take a proacRve iniRaRve in upgrade programs
within the internaRonal collaboraRon at both the accelerator anddetector faciliRes.
Intend to par*cipate in the upgrade

The LHC/ATLAS upgrade review was held by IPNS, KEK in November, 2013.
8ILC
KEK will play a central role in creaRng an internaRonal preparatorygroup and will lead the eﬀort on advanced R&D, the engineering
design of the apparatus and facility, and the organizaRonal design
toward groundbreaking for the linear collider project to be hostedin Japan, within the framework of a global collaboraRon.
In accordance with the Japanese HEP community’s proposal
As the ﬁrst step, KEK set up the PlanningOﬃce for the ILC in January 2014.

9Photon Science (Synchrotron RadiaRon Research)
KEK will conRnue 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 Rme, 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 potenRal of the ERL as a new accelerator to open new scienRﬁcfronRers, KEK will work toward construcRon of a 3 GeV ERL facility. In addiRon, KEK
will conRnue to play a leading role in the development of synchrotron radiaRon (SR)research in Japan.
CompleRon of the c‐ERL construcRon this year
Addendum to KEK roadmap 2013 in October 2013
While KEK is engaged in a long‐term eﬀort toward construcRon of a 3 GeV ERL facility,
KEK will playa leading role in the realizaRon of a low‐emiAance storage ring as a high‐brilliance light source in the mid‐term. KEK is now beginning speciﬁc studies on thispossibility with eyes on the value of naRon‐wide eﬀort. Such a light source facility with highbrilliance, currently not present in Japan, is strongly desired by user communiRes in a wide
range of academic and industrial ﬁelds, and is considered to be an indispensable researchplanorm in the near future.

Execu*on of the short term plan and R&D for future:
A mid‐term plan to be updated

New development of accelerator and detector technologies
KEK will contribute its expert knowledge and technicalcapabiliRes with respect to parRcle accelerators anddetectors to collaboraRon with scienRsts from researchﬁelds of overlapping interest and to numerous industrial
and medical applicaRons for the beneﬁt of society. KEK will
also promote research that has the potenRal tosigniﬁcantly expand accelerator and detector technologies
in the long term.

Research AdministraRon Department• KEK established a new department to support
research promoRon according to the KEK
Roadmap. This is a new program to besupported by MEXT for the next 10 years.
• KEK intends to promote cooperaRon withindustries and universiRes for innovaRon andglobal cooperaRon with research insRtutes
abroad for accelerator based science under
this new program.

Summary• KEK established a new roadmap for research
for the next ﬁve years (with a possible update
for the mid‐term plan of the photon science).
• It clariﬁes goals of on‐going programs andpreparaRons for the future.
• ImplementaRon towards realizing theroadmap has started.
