Japan's High Energy Accelerator Research Organization (KEK) issued an KEK-ILC action plan for how KEK should start its preparation toward the International Linear Collider when the Ministry of Education, Culture, Sports, Science and Technology (MEXT), decides to initiate negotiations with foreign countries.
KEK has been promoting the development of linear collider accelerator technology for a long time and has greatly contributed to the publication of the ILC Technical Design Report (TDR). KEK considers the promotion of the ILC project to be a strategic part of organization's future, described in the KEK Roadmap published in May 2013. Its activities are currently centered around three facilities: the Superconducting RF Test Facility (STF), the Accelerator Test Facility (ATF), and the Cavity Fabrication Facility (CFF). In addition to the efforts in the technical development,, KEK established the Planning Office for the ILC in February 2014, to promote the ILC project and the technical development activities at KEK.
This report summarizes the study made by the working group set under the Director General, focusing on the human resources and actions necessary from starting the main preparation phase, to starting the ILC construction project under an international agreement. The study provides the basic information required to plan the technical actions, organization, human resources, and training to realize formal approval of the ILC project, and to ensure a smooth start of the construction phase through the preparation phase from the current status.
International Linear Collider (ILC)：
The International Linear Collider (ILC) is a next-generation energy frontier electron-positron collider. It will reach a center-of-mass energy of 500 GeV in the first stage, and can be upgraded to an energy to 1 TeV in the future. It aims to precisely measure the properties of the Higgs particle and Top quark, discover new particles and phenomena, and search for new physics beyond the Standard Model of elementary particle physics.
In May 2014, MEXT established the ILC Advisory Panel (ILC-AP), and has been studying issues pointed out by the Science Council of Japan (SCJ). In June 2015, MEXT ILC-AP produced a report, "Summary of the International Linear Collider (ILC) Advisory Panel's Discussions to Date".
