Challenges & Bottlenecks: Technical, Economic, and Geopolitical Risks

Lanthanide-based neutron beamline engineering is rapidly advancing, but several persistent challenges and bottlenecks could influence progress in 2025 and beyond. These risks span technical, economic, and geopolitical domains, each with direct implications for the reliability and scalability of neutron science infrastructure.

Technical Challenges

  • Material Purity and Consistency: High-purity lanthanides are essential for neutron beamline components such as moderators and detectors. Achieving the ultra-high purity required for scientific-grade applications remains technically demanding due to the lanthanides’ chemical similarity and the complexity of their separation. Even major suppliers such as American Elements and Solvay acknowledge ongoing purification constraints, which can impact performance and reproducibility.
  • Irradiation Stability: Lanthanide-based materials can suffer from radiation damage under sustained neutron flux, leading to performance degradation and frequent maintenance. Facilities such as the Oak Ridge National Laboratory and the ISIS Neutron and Muon Source are actively researching new alloys and composite structures to improve lifespan and reliability, but solutions are still in development.

Economic Bottlenecks

  • Supply Chain Volatility: Lanthanide sourcing is concentrated in a few geographic regions, making supply chains vulnerable to fluctuations in mining output and export policies. The LANXESS rare earths division and Chemours have noted increased scrutiny over supply chain transparency and ethical sourcing, which could tighten markets and elevate costs.
  • Cost of Advanced Separation: The financial burden of refining and separating lanthanides for beamline use is significant. This has led to higher procurement costs for neutron facility upgrades and expansions, as seen in recent budgets from European Spallation Source projects.

Geopolitical Risks
