With over 40 years’ experience designing and developing quadrupole mass spectrometers, Hiden Analytical is a leading manufacturer of scientific instruments for advanced research and specialist process monitoring. Driven by customer- and application-focused innovation, Hiden works in partnership with users to deliver leading-edge products that extend analytical capability and strengthen confidence in results.

Hiden’s portfolio spans precision gas analysis, plasma diagnostics by direct measurement of plasma ions and ion energies, SIMS probes for UHV surface science, catalysis performance quantification and thermo-gravimetric studies, covering pressures from 30 bar processes down to UHV/XHV. Global reach is strengthened by local representation across the Americas, Europe, the Middle East & Africa, and Asia & Pacific, supported by dedicated sales and service centres and experienced application specialists.

Fusion research and technology place exceptional demands on vacuum integrity, gas purity and real-time diagnostics. Hiden systems support fusion-relevant workflows including residual gas analysis for contamination tracking, vacuum and leak verification during commissioning and maintenance, and plasma–surface interaction studies where sensitive detection of light gases and trace species is essential. Hiden helps laboratories reduce risk, improve uptime, and accelerate fusion. From RGA to plasma ion analysis, our instruments support cleaner vacuums, safer operations, and better reproducibility in fusion R&D.

The HUN-REN Centre for Energy Research is active both in fission and fusion nuclear energy technology development, with a strong emphasis on applied research, engineering development, and international collaboration. The Fusion Plasma Physics Department (FPLab) plays a central role in bringing together plasma physicists and engineers, enabling activities that span from fundamental plasma diagnostics to the design and construction of reactor-relevant systems.

FPLab has more than three decades of experience in fusion research and over two decades of participation in Euratom/EUROfusion programmes, working closely with major international facilities like ITER, JT-60SA, Wendelstein 7-X, ASDEX Upgrade, MAST Upgrade, KSTAR, EAST and BEST. A core competence of the department is the development of active beam and optical diagnostics, including beam emission spectroscopy, high-speed video diagnostics, synthetic diagnostics and advanced data evaluation and modelling techniques. These activities are closely related to experimental operation and theory, ensuring direct relevance for present-day and next-step fusion devices.

A strategic focus area is cryogenic pellet technology, covering shattered pellet injection for disruption mitigation, fuelling pellet systems, and supporting cryogenic infrastructure. FPLab operates an ITER DMS Support Laboratory and develops fuelling pellet solutions for JT-60SA and other devices.

In addition to academic research, Hungarian fusion industry partners are closely integrated into these activities through direct ITER contracts and joint developments with the Research Centre. FPLab welcomes industrial and institutional collaborations in diagnostics, cryogenics, design, modelling and prototype development.
