Ultra-high-field superconducting magnets serve as a core infrastructure for modern scientific exploration and cutting-edge technological development. They combine zero electrical resistance with high magnetic fields under ultra-low temperature conditions, offering a unique combination of low operational energy consumption, high magnetic field strength, and exceptional field quality. As a critical enabling technology for generating extreme conditions, ultra-high-field superconducting magnets play an irreplaceable role in discovering new states of matter, revealing new laws, and enabling novel technologies. They serve as a strategic tool underpinning frontier breakthrough in fields such as condensed matter physics, materials science, life sciences, and brain sciences. Ultra-high-field superconducting magnets have become indispensable core components in high resolution analytical instruments (ultra-high-field nuclear magnetic resonance spectrometer), advanced medical equipment (ultra-high-field magnetic resonance imaging system), and fusion energy applications (nuclear fusion devices). Currently, global research is undergoing a profound shift from low-temperature superconducting materials (e.g., NbTi, Nb3Sn) toward high-temperature superconducting materials (e.g., REBCO). On one hand, this transition leverages REBCO to surpass the field-strength limits of low-temperature superconductors, targeting higher magnetic field (≥40 T). On the other hand, it pursues more compact, efficient, and cost-effective solutions, achieving cryogen-free or reduced-cryogen operation through high-temperature superconductor technology and promoting the widespread adoption of superconducting magnets in industrial applications.

In recent years, China has achieved a series of breakthroughs in the field of ultra-high-field superconducting magnets, establishing a complete innovation chain spanning from fundamental research to core equipment. Following the successful development of a 32.35 Tesla all-superconducting magnet, China achieved the development of a 35.6 Tesla all-superconducting user magnet in January 2026, establishing its world-leading position in the field of all-superconducting user magnets. In the field of advanced medical equipment, the successful development of a 9.4 Tesla whole-body magnetic resonance imaging superconducting magnet with an 800 mm warm bore has made China the first country in Asia to master this technology, providing an autonomous and advanced tool for brain cognitive science research and the early diagnosis of neurodegenerative diseases. Moreover, the breakthrough in developing a 16.5 Tesla general-purpose superconducting magnet with a 150 mm warm bore demonstrates the growing maturity in the development capability of large-bore, high-field magnets.These achievements have realized full-chain autonomy and controllability spanning key materials, core processes, and system integration, providing robust support for major strategic initiatives in China, including integrated extreme condition research, advanced scientific instrumentation, and future fusion energy.

In the future, global ultra-high-field superconducting magnet technology will continue to evolve toward higher magnetic field, larger clear bore diameter, enhanced stability, and improved cost-effectiveness. China has set its sights on the development of 40 Tesla and above all-superconducting user magnets, and is simultaneously advancing the development of nuclear magnetic resonance superconducting magnets with larger bore diameter and higher field homogeneity to meet the broader needs of scientific experiments and engineering applications. Concurrently, the development of high-temperature superconducting magnet technologies featuring cryogen-free operation, compactness, and persistent current mode will continue to advance, addressing the challenges posed by the scarcity of helium resources. Continued breakthroughs by China in this field will not only contribute critical experimental capabilities to global exploration at the frontiers of basic science, but will also provide core support for the development of next-generation advanced medical equipment and major scientific infrastructure.

Marcel ter Brake received his doctoral degree in 1986 at the University of Twente (UT) after which he became member of the UT/Low-Temperature-Division. Focus of his work was on SQUID-based magnetometer systems, that all were liquid-helium cooled. The advent of high-temperature superconductivity in 1986 allowed the use of small cryocoolers, and the interfacing of these coolers to ultra-sensitive devices such as SQUIDs became an important field of Marcel’s research. In this work, he started a project on MEMS-based microcoolers in 1995. Since the end of the 90’s, in addition to microcooling, research was performed on sorption-based compressors combined with Joule-Thomson cold stages. These sorption coolers are essentially vibration free and are of interest specifically for space missions but can also be beneficial in terrestrial applications.
Marcel ter Brake was appointed Associate Professor at UT in 2000, and Full Professor and chair holder of Energy, Materials and Systems at UT per January 1st 2010. Marcel retired in April 2024. He has been board member of the International Cryocooler Conference, co-founder and chairman of the Cryogenics Society of Europe, and committee member and chairman of the International Cryogenic Engineering Committee. He is lifetime member of the Cryogenic Society of America and honorary member of the Cryogenics Society of Europe.
Marcel ter Brake has published more than 230 papers, of which more than 130 in refereed journals. He has been awarded the Samuel C. Collins Award of the Cryogenic Engineering Conference in 2023.

The University of Twente was founded in 1961 as Technische Hogeschool Twente (THT). After Delft University and Eindhoven University, it became the third polytechnic institute in the Netherlands to become a university. The Dutch government decided to locate the country's third technical university in Enschede, the largest city of the region Twente, in the East of the Netherlands. In 1986, the university was renamed to Universiteit Twente (University of Twente).
At the start of the university, Physics was embedded in the curriculum on Electrical Engineering. As part of the Physics practicum, Leen van der Marel and Louis van der Klundert started a cryogenic laboratory in 1967 equipped with a Philips helium liquefier. Experiments were performed on material properties much in the tradition of the Kamerlingh Onnes Laboratory in Leiden, the ‘home base’ of Van der Marel.
In 1969, Applied Physics was started at THT as a separate curriculum, positioning itself between fundamental physics and engineering, focusing on utilizing scientific principles for practical devices. One of the research chairs in this department was ‘Low Temperatures (LT)’ led by prof. van der Marel. As before, the research focused on material properties, with specific interest in energy transfer between phonons and spins in magnetic systems such as Cerium Magnesium Nitrate. These materials were characterized through a.c. magnetic susceptibility measurements in experimental setups equipped with mutual inductance bridges. Higher sensitivity, specifically at low frequencies, was realized by using superconducting magnetometers (SQUIDs) for read-out and superconducting magnets for applying high background fields.
Apart from the study on materials, two lines of research developed, both on applications of superconductivity: first, the application of the extremely high current density achievable in superconductors in high-field magnets, and second, the application of the quantum-mechanical character of superconductivity, in sensors and thin-film devices. The first line was led by Louis van der Klundert, and after Louis’ passing in 1991 by Herman ten Kate. The second line on superconducting devices was led by Jaap Flokstra and Horst Rogalla (successor of prof. van der Marel who retired in 1985).
The discovery of high-temperature superconductivity in 1986 propelled the research in the Low Temperature division enormously, as it did worldwide stimulate research on superconducting materials and applications. In addition, since the operating temperature of superconductors increased to relatively high temperatures, it became ‘easier’ to apply mechanical cryocoolers for cooling instead of liquid cryogens. This in turn stimulated the development of more efficient and more reliable cryocoolers. Pushed by these developments, LT grew to about 60 members, which caused the Faculty to gradually split up LT in five separate research chairs at the time of Horst Rogalla’s retirement in 2010. One of these chairs is Energy, Materials and Systems (EMS) that I had the pleasure to lead until my retirement in 2024, after which Hans van Oort took over.
At its start in 2010, in EMS the research on high-current applications of superconductivity continued, next to the further developments in advanced cryogenic technologies and in cryogenic mass and heat transfer. Major achievements were established in projects such as the EU-EcoSwing project in which the world’s first superconducting generator was realized and installed in a 3.6 MW wind turbine that provided power in the grid.
In all the above-mentioned research, cryogenics is a key enabling technology. In this presentation, next to the historical perspective, I will focus on the cryogenic engineering aspects in the past of LT, more recently in EMS, as well as in present EMS projects some of which are also presented at this conference. Topics that will be addressed are:

   - Characterization of superconductors under cryogenic operational conditions
   - Cryogenic mass and heat transfer
   - Application of commercially available cryocoolers
   - Novel cooling technologies (microcooling and sorption-based cooling)

His work spans superfluid helium-4, cryogenic accelerator physics, helium-based dark matter detection, liquid-hydrogen aviation, and quantum devices based on quantum fluids and solids. His group is widely recognized for developing advanced flow-visualization techniques in cryogenic helium and for major contributions to the study of quantum turbulence, including the direct imaging of quantized vortices in superfluid helium. He has also contributed to emerging trapped-electron qubit platforms based on solid neon and related quantum materials systems.

His contributions have been recognized by election as a Fellow of the American Physical Society in 2023, the Gordon and Betty Moore Foundation Experimental Physics Investigators Award in 2022, the Outstanding Research Accomplishment Award from the FAMU-FSU College of Engineering in 2023, and the JSPS Invitation Fellowship. Through his research, leadership, and interdisciplinary collaborations, he has played an important role in advancing cryogenics, quantum materials, and quantum engineering at Florida State University and the Maglab.

The Cryogenics Laboratory at the National High Magnetic Field Laboratory at Florida State University, founded by Dr. Steven Van Sciver, has long been recognized for its contributions to helium fluid dynamics, cryogenic heat transfer, and low-temperature materials characterization. Over the past decade, since I assumed leadership of the laboratory, our research has expanded in important new directions. Alongside continued efforts in cryogenic engineering, we have advanced the study of quantum fluid dynamics in superfluid helium-4 (He II), with particular emphasis on flow visualization of quantized vortices and quantum turbulence. We have also launched new research programs aimed at harnessing quantum fluids and solids for emerging applications in quantum information science. In this presentation, I will discuss our recent progress in probing and exploiting the remarkable quantum properties of He II for both fundamental science and cryogenic applications, and I will also highlight our work on developing a new qubit platform based on single electrons trapped on solid neon surfaces.

I will begin with an overview of the remarkable physical properties of He II and their broader significance. In particular, I will discuss how its two-fluid nature, quantized vortices, and unusual thermal and hydrodynamic response sharply distinguish He II from classical liquids and make it an ideal medium for exploring macroscopic quantum phenomena. These features open a unique window into nonequilibrium quantum dynamics across a wide range of length and time scales, while also underpinning the value of He II as a functional material for advanced cryogenic and quantum systems.

I will then discuss our studies of He II using advanced flow-visualization techniques. Our laboratory has developed powerful optical methods that provide direct experimental access to a broad class of phenomena in He II. On the fundamental side, these techniques have enabled us to image quantized vortex dynamics and probe striking processes such as vortex reconnections, Kelvin-wave excitations, anomalous vortex diffusion, and the propagation of quantized vortex rings. These studies have yielded new insights into quantum turbulence, dissipation mechanisms, and coherent vortex structures in superfluids, further establishing He II as a powerful model system for quantum-fluid physics. Beyond fundamental science, the same visualization tools have opened new avenues for practical cryogenic applications, including high-precision quench-spot diagnosis in superconducting radio-frequency cavities and direct measurements of near-wall flow structures relevant to friction and heat transfer in He II engineering systems.
In the third part, I will highlight our recent work on developing novel qubit platforms based on single electrons trapped on cryogenic surfaces. Over the past two decades, electrons on He II have attracted sustained interest as a potential qubit platform because they provide an exceptionally clean environment, with electrons naturally suspended in vacuum above the helium surface. Yet, despite extensive efforts, successful qubit operation has not been demonstrated, due in part to liquid-surface fluctuations and the associated decoherence. These limitations have motivated the search for alternative cryogenic hosts. Electron-on-neon (eNe) qubits have recently emerged as a compelling platform for quantum computing, combining the excellent vacuum isolation with the strong scalability and on-chip integration prospects of superconducting circuits. While recent experiments have demonstrated the promise of this platform, significant challenges still remain in scaling it to larger and more controllable qubit arrays. Motivated by this need, we are exploring new solid-neon architectures based on arrays of magnetically levitated solid-neon microparticles, aiming to advance scalable eNe-based quantum computing.

Overall, this presentation will show how the Cryogenics Laboratory at the MagLab has evolved from its traditional strengths in cryogenic engineering into a broader program spanning quantum fluid dynamics, cryogenic diagnostics, and quantum-device concepts based on cryogenic matters. From revealing the rich dynamics of quantized vortices in He II, to enabling new diagnostic tools for cryogenic accelerator systems, to advancing innovative trapped-electron qubit architectures, this work highlights the expanding role of cryogenic quantum matter in both fundamental discovery and emerging technologies.
