Its central element is the IFMIF‑DONES facility, a unique neutron source to be built in Escúzar (Granada, Spain), designed to reproduce the irradiation conditions expected inside fusion reactors. This will allow scientists to test, validate, and qualify structural materials essential for next‑generation fusion facilities such as DEMO.
The Programme is governed by the Multilateral International DONES Agreement (MIDA). MIDA provides a robust and transparent framework defining the Programme’s objectives, governance structure, decision‑making processes, and the rules for financial and in‑kind contributions by participating Partie
Covering the full lifecycle of the infrastructure—from construction and commissioning to operation and decommissioning—the DONES Programme brings together countries, research organisations, and experts in a long‑term collaborative effort. Through shared governance and international cooperation, DONES is a cornerstone of the global fusion roadmap and a key enabler of clean, safe, and sustainable energy for the future.
