TL;DR
This paper reviews the current status, engineering progress, and cost estimates of the International Linear Collider (ILC) project considered for Japan, aiming to inform global strategic discussions without detailing the physics goals.
Contribution
It provides an update on the technical progress, cost estimates, and Japan's involvement in the ILC project to support international planning efforts.
Findings
Progress in engineering studies for the ILC
Updated cost estimates for a 250 GeV collider
Overview of Japan's role in the project
Abstract
This paper is not a proposal for a CERN future project but provides information on the International Linear Collider (ILC) considered for Japan in order to facilitate the European Strategy discussion in a global context. It describes progress to date, ongoing engineering studies, updated cost estimate for the machine at and the situation in Japan. The physics of the ILC is not presented here, but jointly for all Linear Collider projects in a separate document ``A Linear Collider Vision for the Future of Particle Physics'' submitted for the forthcoming European Strategy deliberations.
