NMR & MRI

Buyer Decision Criteria

• Bore diameter, useful imaging or measurement volume, and field strength.
• Homogeneity target and acceptable correction strategy.
• Temperature stability, drift control, and material grade.
• Handling, shielding, and export packaging needs for strong bore magnets.

Factory Support Scope

• Segmented Halbach cylinder assembly for dipole and multipole fields.
• Bore mapping and homogeneity support for prototype validation.
• Magnet sorting and angular fixture control.
• NdFeB or SmCo grade selection by stability and temperature needs.

RFQ Preparation Checklist

1. Bore diameter and required Tesla rating
2. Useful field volume and homogeneity target
3. Temperature stability and correction strategy
4. Weight, handling, shielding, and mapping report needs

Risk and Mitigation

• Thermal drift: Passive or active thermal shielding design.
• Homogeneity target not manufacturable in the requested envelope: Review bore size, segment count, grade, sorting, and correction strategy before quote freeze.
• Ambiguous mapping acceptance: Define probe path, useful volume, temperature, and ppm metric before sample production.

Validation Deliverables

• Bore field map with measurement volume definition.
• Segment angle and cylinder dimension inspection.
• Material grade, coating, and orientation documentation.
• Packaging and handling notes for instrument teams.

RFQ to Delivery Flow

1. Send bore, field, homogeneity volume, temperature range, and instrument constraints.
2. We review field target and manufacturable segment geometry.
3. Prototype mapping verifies the bore field before production approval.
4. Production follows matched magnet sorting and approved mapping controls.
