Fusion & Plasma Research

Achieving controlled nuclear fusion via Magnetic Confinement Fusion (MCF) devices such as tokamaks, stellarators, and mirror machines: requires extraordinarily strong and precisely shaped magnetic fields to contain and control superheated plasma. Similarly, fundamental plasma physics research and applications like particle accelerators or specialised beamlines rely on tailored magnetic environments.

HTS technology, particularly using advanced ReBCO tapes, offers significant advantages over traditional Low-Temperature Superconducting (LTS) systems for these demanding applications.

Our cryogen-free HTS magnet solutions are engineered to provide:

Higher Field Strength: HTS enables stronger magnetic fields than LTS leading to smaller, more efficient, faster to develop fusion reactors. 

Truly Cryogen-Free Operation: Simplifies complex engineering and cryogenic infrastructure by eliminating liquid helium dependence, mitigating “Helium Shortage 4.0” risks and costs. This allows for rapid cooling and setup.

Enhanced Stability & Quench Management: HTS offers higher thermal stability margins. HTS-110 integrates robust monitoring (temperature, voltage) and protection systems, leveraging extensive experience to ensure reliable operation crucial for long-duration plasma experiments.

Compactness & Design Flexibility: Higher current density in HTS conductors allows for more compact magnets. We offer options for room temperature or cold bore, adaptable for various temperature control needs.

Advanced Shielding & Field Control: Sophisticated passive and active shielding options ensure precise field control and minimal fringe effects.

Versatile Supports & Orientation: Our magnet systems can be designed for any field orientation to suit diverse experimental setups.

Faster Ramping: The enhanced thermal stability of HTS materials allows for fast magnetic field change, beneficial for certain control schemes or experimental protocols.

Fusion companies choose HTS-110 for their HTS magnet requirements rather than developing the technology in-house, enabling them to benefit from our deep manufacturing experience and shortcut their development timelines. We offer:

• Custom HTS Magnet Systems. We design and manufacture bespoke magnets, including complex coil geometries for specific confinement schemes or field-shaping. Our systematic, end-to-end approach—from initial design study and feasibility analysis through to modelling, manufacturing, testing, and commissioning—minimises technical risk and respects client intellectual property at all times.
• CryoForge™ HTS Coils. We supply high-performance HTS coils (circular, racetrack, non-planar) as building blocks for larger magnet assemblies, incorporating refined mechanical reinforcement and quench protection.
• CryoSaver™ HTS Current Leads. Our thermally efficient, high-current leads (standard up to 3 kA, custom higher) are essential for powering large superconducting magnets and are field-proven in over 2000 installations worldwide.
• HTS Wire Characterisation Ecosystem. While not operated in-house, our close collaboration with wire suppliers and the Robinson Research Institute (developers of the SuperCurrent™ system) informs our magnet designs. This ecosystem enables rigorous Jc measurements, transport property analysis, flux pinning studies, and stability testing crucial for qualifying HTS wire for reactor-scale magnets under realistic operating conditions.

Beyond confinement magnets, HTS-110’s versatile magnet platforms support essential research and diagnostic techniques relevant to fusion materials and plasma physics:

Materials Characterisation. Understanding material behaviour under relevant conditions is crucial. Our systems enable:

• Variable-Field Transport Studies: Including Hall effect measurements and Magneto-resistivity & anisotropy measurements to probe electronic properties.
• Magnetic Property Characterisation: Facilitating Magnetic hysteresis analysis using systems like our Fast-ramping Dipoles (proven in industrial data storage R&D) or developmental SCM-Magnetometer. Techniques like Magnetic domain imaging or Magneto-optic Kerr effect (MOKE), enabled by various HTS-110 magnets, can probe surface magnetism relevant to plasma interactions or diagnostic components.

Diagnostics and Calibration. Hall Probe Calibration: Our 3 T Metrology Magnet and Dipoles provide the stable, uniform fields needed for calibrating magnetic field sensors.

Fundamental Physics.

• Beamline Sample Environments: Our expertise in providing magnets for neutron and X-ray scattering allows for in situ studies of materials under magnetic fields.
• Particle Accelerators: Demonstrated capability in retrofitting accelerator dipoles with HTS coils.
