Slovenian Fusion Association (SFA)

SFA coordinates the fusion research in Slovenia, including plasma-wall interaction, material science, neutronics, thermo-hydraulics, safety analyses, modelling, diagnostics and control systems. The association has been part of EUROfusion since 2005.

About 50 researchers, experts, PhD candidates and post-docs are involved in SFA’s fusion research.

SFA is led by its largest member, the Jožef Stefan Institute (JSI) with eight research departments.

It includes the University of Ljubljana (UL), the Institute of Metals and Technology (IMT) and the company Cosylab as associated entities.

The linear 2 MV Tandetron Accelerator at JSI with its 4 beam lines is used for plasma-wall interaction studies. Ion beam analytical methods are applied to study plasma-wall processes on ITER and DEMO relevant materials. In the field of material science, JSI uses FAST sintering to develop tungsten-based composite materials for high heat flux components of the DEMO divertor.

JSI performs thermal-hydraulic, structural and safety analyses in support of DEMO tokamak design, development of high-heat-flux components for Wendelstein 7-X and Divertor Test Tokamak (DTT). Neutronics studies carried out at JSI are used for JET neutron yield calibration and to support the development of DEMO design.

SFA researchers actively participate in experimental campaigns in EU tokamaks JET (UK), AUG (Germany) and TCV (Switzerland). Faculty of Mechanical Engineering (University of Ljubljana) is developing simulation tools for integrated tokamak modelling. Cosylab is developing the control system CODAC (Control, Data Access and Communication) for ITER.

Jožef Stefan Institute (JSI)

The Jožef Stefan Institute is the leading Slovenian scientific research institute, covering a broad spectrum of basic and applied research. The staff of about 1050 specializes in natural sciences, life sciences and engineering.

The subjects concern production and control technologies, communication and computer technologies, knowledge technologies, biotechnologies, new materials, environmental technologies, nanotechnologies, and nuclear engineering.

At Jožef Stefan Institute, eight research departments are involved in the fusion-related research, including materials’ development, plasma-wall interaction studies, thermal-hydraulic, structural and safety analyses and neutronics studies.
