2. LCC Mandate
The mandate of the LCC is to support the global design effort to enable the possible realization of a timely electron-positron collider and its detectors based on ILC technology, to support the CLIC technology development for a potential future higher energy machine and to coordinate both efforts in order to exploit synergies between them. It finishes in December 2016.

4. The CLIC project
2012 CLIC CDR submitted, input to the European Strategy process.
The CERN LC activities now address:
High Gradient acceleration, machine studies for high energy frontier e+e- (CLIC)
European ILC effort
General accelerator and detector R&D
Main actvitiy: CLIC Development Phase
Develop a Project Plan for a staged implementation in agreement with LHC findings; further technical developments with industry, performance/optimisation studies for accelerator parts and systems, as well as for detectors.
Key features:
High gradient (energy/length)
Small beams (luminosity)
Repetition rates and bunch spacing (experimental conditions)
Mention collaborative agreement (~60-70) and 80 students covering when talking about collaboration
Often linked to local project where “CLIC or LC technologies” exist or are essential for their future plans
Accelerator collaboration with ~50 institutes
Detector collaboration operative with ~25 institutes

5. Nanobeam studies in ATF and FACET
Main Linac Tolerances
Nanobeam studies in ATF and FACET
The CLIC coll. is very interested in a longer term programme at ATF2 - ongoing:
FFS performance, including building 2 octupoles for ATF2 (to study FFS tuning with octupoles – being built)
Stability, feedbacks, instrumentation
General support for ATF2 operation
Support UK and Spanish LC activities (contracts with 7 universities with 50/50 sharing) that are have a significant ATF component
Key elements for performance being addressed with specific developments or tests: alignment, stability, damping systems, wakefield monitors (CTF3 in progress), damping rings performances and elements -> wanted to complement by beam based alignment system performance verification (FACET)

MEXT Commissioned Survey

7. JFY2015, Commissioned Survey by MEXT contracted with Nomura Research Institute (NRI)
Subjects for survey and analysis:
Technical feasibility to realize the ILC
Regarding components, system design, management, and infrastructure
Technical issues to prepare for the ILC construction
Regarding industrial technology, and necessary time-scale, and prototype works.
Cost increase risk
Cost reduction possibility
with technical approaches not described in TDR

9. MEXT advisory panel
Recommendation 1: The ILC project requires huge investment that is so huge that a single country cannot cover, thus it is indispensable to share the cost internationally. From the viewpoint that the huge investments in new science projects must be weighed based upon the scientific merit of the project, a clear vision on the discovery potential of new particles as well as that of precision measurements of the Higgs boson and the top quark has to be shown so as to bring about novel development that goes beyond the Standard Model of the particle physics. Recommendation 2: Since the specifications of the performance and the scientific achievements of the ILC are considered to be designed based on the results of LHC experiments, which are planned to be executed through the end of 2017, it is necessary to closely monitor, analyze and examine the development of LHC experiments . Furthermore, it is necessary to clarify how to solve technical issues and how to mitigate cost risk associated with the project.

10. Recommendation 3: While presenting the total project plan, including not only the plan for the accelerator and related facilities but also the plan for other infrastructure as well as efforts pointed out in Recommendations 1 & 2, it is important to have general understanding on the project by the public and science communities.

11. HR working group
At the meeting on 20th April (probably the last before the final report), a presentation was made of the human resources and organizational structure needed to build the LHC. I was invited as an observer, the first non-Japanese.

12. The future of LCC
Japan has made it clear that no decision on ILC will be made before Is it necessary to keep a structure in place to hold together the International community until this decision is made?

13. Recent information
Recent more positive interaction between between the Japanese government (MEXT) and the US/DOE. Strong international support is essential. The International community is strongly encouraged to send as many people to the LCWS in Morioka in December,
