Ruben Fair

BOARD ADVISOR, Magnet Design / Magnet Shielding

Ruben Fair is a Board Advisor at Kronos Fusion Energy, specializing in Magnet Design and Magnetic Shielding. He is currently the US ITER Department Head at Princeton Plasma Physics Laboratory (PPPL). With extensive experience in leading highly technical global teams and working on superconducting magnets, vacuum chambers, cryogenics, low-temperature equipment, and rotating electrical machines, Ruben brings valuable expertise to the Kronos Fusion Energy team.


Fair earned his BSc. (Hons.) Eng. degree and Ph.D. degree in Electrical Engineering from the Imperial College of Science and Technology, London, U.K., in 1985 and 1991, respectively. He began his career at GEC-Alsthom Large Machines, Ltd., as a Hydro generator Design Engineer in 1988, before joining Oxford Instruments (NMR Division) in 1994 as a Design and Development Engineer. At Oxford Instruments, he worked on a range of new superconducting magnets, including the world's first persistent 21 Tesla, 900-MHz NMR magnet.


In 1999, Fair became a Principal Engineer at Oxford Instruments (Research Instruments), where he led a team developing superconducting magnets and ultra-low-temperature refrigerators for the physics community. He later led the New Product Introduction engineering team at Oxford Instruments Nanoscience. In 2007, he joined Converteam (now General Electric Power Conversion), where he led a team to develop the world's first high-temperature superconducting hydro generator and set up a Cryogenics Laboratory.


In 2010, Fair was recruited by General Electric Global Research Center to develop a strategic roadmap for a range of superconducting machines. He then joined Jefferson Laboratory in 2013 as a Principal Engineer, leading a team overseeing the design, build, installation, and commissioning of eight superconducting magnets for the 12 GeV accelerator upgrade project. He later led the Magnet Group within the Experimental Nuclear Physics Division at Jefferson Lab.


Dr. Fair has contributed to various publications, including a chapter in High Temperature Superconductors (HTS) for Energy Applications (Woodhead Publishing, 2011), and holds several patents.


He is a Technical Editor and Reviewer for the IEEE Transactions on Applied Superconductivity, a Chartered Engineer, a Member of the Institute of Engineering and Technology (U.K.), and a Senior Member of the IEEE (USA). Currently, as the department head for fusion diagnostics at PPPL, he leads the team responsible for the design and construction of diagnostic instruments for the international fusion experiment ITER under construction in Cadarache, France.
