Controlling fusion plasmas over long durations — while gaining experience with steady-state or long-pulse operation supported by active cooling systems that keep plasma facing components at stable temperatures — is essential for the success of ITER and future fusion facilities.

To support coordination on these challenges, the International Atomic Energy Agency (IAEA) and the International Energy Agency (IEA) established in 2020 the network for Coordination on International Challenges on Long-duration OPeration (CICLOP). The objectives of the CICLOP group are to promote collaborative activities and to collect and disseminate information on the physics and engineering aspects of long-pulse operation in tokamak and stellarator facilities. This includes sharing best practices, operational procedures, experimental data, and simulation programmes, as well as coordinating experiments among the fusion-related IEA Technology Collaboration Programmes in close cooperation with the IAEA’s activities in this field. These efforts are advanced through a series of IAEA Technical Meetings on Long-Pulse Operation of Fusion Devices.

Objectives

The event aims to review and address the scientific and engineering challenges of steady-state and long-pulse operation, both of which are essential for ITER and future fusion facilities.

Target Audience

The event aims to bring together junior and senior fusion scientists, plasma physicists — including theorists, modellers and experimentalists — and engineers to address the physics and engineering challenges of long-pulse operation in tokamak and stellarator facilities.
