Undulator & Wiggler Magnets

Buyer Decision Criteria

• Period length, gap, peak field, phase error target, and tuning method.
• Radiation environment and SmCo versus NdFeB material decision.
• Magnet sorting method, pole support, and mechanical adjustment strategy.
• Documentation depth needed for lab procurement and acceptance testing.

Factory Capability

• Individual magnet measurement and sorting before assembly.
• SmCo grade support for radiation-sensitive environments.
• Precision carrier machining for repeatable period and gap control.
• Prototype module builds for customer field characterization.

RFQ Checklist

1. Period length (lambda)
2. Gap size
3. K-parameter requirements
4. Peak field, phase error target, material constraints, and documentation needs

Risk Controls

• Radiation degradation: Use of Samarium Cobalt (SmCo) magnets instead of NdFeB in high-radiation zones.
• Field error caused by unmeasured magnets: Measure and sort individual magnets before assembly when phase-error targets are tight.
• Procurement rejection due to incomplete documentation: Align material, measurement, sorting, and inspection records before production release.

Validation Deliverables

• Individual magnet measurement records when required.
• Assembly dimension and period inspection.
• Field profile support for phase-error review.
• Material and magnetization direction documentation.

RFQ to Delivery Flow

1. Share period, gap, K target, field tolerance, material preference, and documentation needs.
2. We confirm sorting and carrier strategy before prototype order.
3. Prototype modules support lab-side magnetic characterization.
4. Production repeats the approved magnet sorting and carrier datum method.
