The IEA provides support for international collaboration on energy technology R&D, deployment and information dissemination. These groups function within a framework created by the IEA - the International Framework for International Energy Technology Collaboration. The views, findings and publications of these international groups (formally called Implementing Agreements) do not necessarily represent the views or policies of the IEA Secretariat or of all its individual member countries. OECD Member countries, autonomous OECD non-member countries, intergovernmental organisations, non-governmental organisations and private sector entities may participate.

Reversed Field Pinches

Reversed Field Pinches (RFPs) are one of the possible magnetic confinement alternatives to the tokamak concept, which is the main fusion magnetic confinement option. The RFP concept is less developed than the tokamak but offers potential advantages. The RFP requires a much weaker magnetic field, which may result in a significant advantage for fusion reactors. However, the reduced magnetic field also reduces plasma stability and confinement. Improvement of confinement is one of the major objectives of on-going research.
