Laboratorio Nacional de Fusión

The National Fusion Laboratory is part of CIEMAT.

Logo of the Laboratorio Nacional de Fusión

The Laboratory is dedicated to the development of fusion by magnetic confinement as a future energy generation option. Research is mainly centered on the Flexible Heliac TJ-II, and on materials studies.


In 1975, a research group is created at the JEN (later to become CIEMAT) to study the subject of fusion. In 1983, the small tokamak TJ-I is taken into operation, followed by the torsatron TJ-IU in 1994, and the flexible heliac TJ-II in 1999.

Projects and research

Educational and training activities

The LNF is strongly committed with the education and training of new researchers in the field of magnetic fusion science and technology. It keeps a close collaboration on post-graduate teaching activities with Universities Carlos III, Complutense and Politécnica de Madrid. CIEMAT participates with these two latter institutions in the Campus de Excelencia Moncloa. In the last ten years, in average, three to four PhD thesis/year and four Master Thesis/year are being successfully finished in the LNF facilities.

The LNF is a major Spanish partner of the "European Master of Science in Nuclear Fusion and Engineering Physics (Fusion-EP)", under the auspices of the Erasmus Mundus. In this Master course, international students have six month-stays at LNF and receive lectures given by its staff, among others. LNF is also actively participating in a new Erasmus Mundus programme-related initiative, the Fusion-Doctoral College recently established to host PhD students and supervise their thesis. In both programmes, LNF participates in close collaboration with several national (Complutense and Carlos III, Madrid) and international universities and research institutions (Ghent Univ., Lorraine Univ., Stuttgart Univ., [ Padova Univ.], Instituto Superior Tecnico (Lisbon), ‎IRFM-CEA, IPP-Garching and IPP-Greifswald).

Computer resources

Due to the large computational needs of the Laboratory, it makes use of both internal and external resources through collaborations:


The Laboratory participates in many international projects and collaborates with other institutions, such as:


The Laboratory has organised many events, among which:
