Pellet Injection Technologies
Engineering and development for reliable plasma fuelling.
Fusion Plasma Physics Department
Advancing Fusion through Research and Innovation
From cryogenic pellet systems and fast actuators to advanced plasma diagnostics, we develop and test technologies for today's and tomorrow's fusion devices.
Who We Are
From plasma physics to fusion technology
The Fusion Plasma Physics Department (FPL) of the HUN-REN Centre for Energy Research combines physics, engineering and experimental development to advance controlled fusion energy. We develop, build and operate plasma diagnostics and fusion technologies for leading international research programmes and facilities. Our work spans high-speed video and Beam Emission Spectroscopy, cryogenic pellet production and injection, disruption mitigation, modelling and engineering contributions to ITER, DEMO and IFMIF-DONES. From physical modelling and concept development to mechanical design, construction, testing and operation, our physicists and engineers deliver complete R&D solutions in close collaboration with fusion laboratories across Europe and Asia.
Our technologies and diagnostics have supported major fusion experiments including JET, MAST Upgrade, ASDEX Upgrade, Wendelstein 7-X, EAST, KSTAR and JT-60SA. Today, the laboratory also contributes to ITER through Shattered Pellet Injection technology and to the development of future fusion infrastructure through DEMO and IFMIF-DONES engineering activities.
