Summary
This review paper synthesises four decades of superconducting undulator research and development globally, comparing performance characteristics of NbTi planar designs against permanent magnet alternatives and assessing theoretical limits of different SCU architectures. The authors document successfully commissioned systems at major synchrotron facilities and discuss radiation hardness advantages for deployment in free electron lasers and diffraction-limited storage rings. Key technical challenges in cryostat design, magnetic field measurement, and high-temperature superconductor integration are identified as priority research areas for future compact, high-field undulator development.
UK applicability
This paper is not directly applicable to UK agricultural or food systems research. It addresses advanced physics instrumentation for particle accelerators and X-ray sources, which sits outside the Vitagri domain.
Key measures
Undulator field strength (B₀), period length, photon flux in hard x-ray spectrum, radiation hardness, cryogenic performance
Outcomes reported
This review surveyed worldwide development of superconducting undulators (SCUs) from the late 1970s to 2021, evaluated design requirements and theoretical limits of planar and helical SCU types, and identified technical challenges including cryostat design, magnetic field measurement, field correction, and high-temperature superconductor integration.
