ILC250 Cost Update -- 2024
Abstract
The International Linear Collider was conceived as a global project for an energy-frontier electron-positron collider.It employs superconducting RF and nano-beam technologies with a center-of-mass energy of 500 GeV. Its cost was estimated in 2013, based on the Technical Design Report published in 2013.Japan's high-energy community proposed to host the ILC in Japan as a Higgs boson factory at 250 GeV in its first phase, and a revised cost estimate was conducted in 2017 to host it in Japan. However, due to global price increases and currency fluctuations that emerged afterward, the 2017 estimate is now outdated. A new cost evaluation has therefore been performed, according for global inflation tends, exchange rate shifts, and recent experiences in SRF based accelerators. This report describes the cost update performed in 2024. The cost update is included in the ILC Status Report in May 2025, contributing to the ongoing 2026 update of the European Strategy for Particle Physics.
