From 13 to 23 June 2026, IPPLM Director Dr hab. Monika Kubkowska, Dr Tomasz Fornal and Dr Łukasz Syrocki took part in a research visit to Japan’s National Institute for Fusion Science (NIFS), one of the world’s leading centres for plasma physics and fusion research.
NIFS is home to the Large Helical Device (LHD), the world’s largest heliotron-type stellarator. In December 2025, the device completed its final experimental campaign, bringing nearly three decades of research to a close. The experiments conducted on LHD have made a significant contribution to the development of plasma physics and technologies related to controlled nuclear fusion.
The visit provided an opportunity to review the results of the cooperation between IPPLM and NIFS to date and to discuss the next stages of the analysis of experimental data collected during the final LHD campaign.
An important part of the programme was a scientific seminar delivered by Dr Łukasz Syrocki, entitled "Quantitative Analysis of Tungsten Impurities and Zeff in W7-X Plasma Using Spectroscopic Methods and Spectral Modelling". The presentation focused on the quantitative analysis of spectra recorded using the Pulse Height Analyzer (PHA) diagnostic installed on the Wendelstein 7-X stellarator in Germany.
The visit marked another stage in the long-standing scientific cooperation between IPPLM and NIFS. It enabled the teams to plan further joint research activities and exchange knowledge and experience between the two institutions.
