LCC

What LCC does

The Linear Collider Collaboration (LCC) coordinates the International Linear Collider (ILC), a proposed 20-kilometer electron-positron linear collider intended to be built in the mountainous Kitayama region of northern Japan (Iwate prefecture). The ILC is designed for precision Higgs boson studies, dark matter and dark energy exploration, supersymmetry searches, and top quark physics, complementing the proton-proton Large Hadron Collider at CERN. Core technology is based on superconducting radio-frequency (SRF) accelerating cavities operating at 1.3 GHz and 1.9 Kelvin, with 9-cell niobium cavities targeting a 35 MV/m accelerating gradient, supported by innovations including damping rings, a nanometer-scale final focus system, a push-pull dual-detector platform, and helical undulator positron production. The ILC International Development Team (IDT), created by the International Committee for Future Accelerators (ICFA) in August 2020, is the central coordinating body, headquartered at KEK in Tsukuba, Japan, with Working Groups on Accelerator (WG1), Physics & Detector (WG2), and a third working group plus an International Expert Panel.

The LCC operates as a global scientific collaboration rather than a commercial enterprise, partnering with KEK (Japan), CERN, DESY (Germany), Fermilab, SLAC, and IFIC (Spain) along with the ILC Technology Network (ITN) and the AAA industry-academic-government consortium. Its products and services are the ILC accelerator design, two detector systems (ILD and SID), the Key4hep simulation framework, the ILC NewsLine newsletter, and coordinated scientific documentation. The business model is entirely based on governmental science agency funding: MEXT (Japan) provides the primary hosting-nation funding with a FY2026 request of 10.5 billion yen, while other contributions flow through CERN, DOE (US), and European national agencies. No commercial revenue, pricing models, or licensing arrangements apply; the facility is estimated to cost 7-9 BCHF in its first stage at 250 GeV, upgradable to 500 GeV or higher.

Revenue model

1. Government Funding / International Contributions: The ILC is funded through international government contributions and scientific agency budgets. The Japanese government (MEXT) has provided budget allocations including ILC-related funding. Other participating countries contribute through their respective physics research agencies. No commercial revenue model applies as this is fundamental scientific research infrastructure.
