Section 1: Introduction The National Synchrotron Light Source II (NSLS-II) division at Brookhaven National Laboratory (BNL) is planning for an upgrade of its storage ring (792-m in circumference) consisting of approximately 800 electromagnets placed in 30 identical cells. As a test of the new upgrade concept, 2 electromagnetic dipoles in 2 adjacent cells will be replaced by hybrid dipoles and quadrupoles built with permanent magnet (PM) blocks. The procurement of these high-performance PM blocks is covered by this Statement of Work (SOW). The precise technical and quality requirements are detailed herein.

Section 2: Scope of Work The Contractor shall provide the facility, equipment, construction of any needed tools and fixtures, personnel, and labor needed to manufacture, inspect, test, and deliver the high-performance permanent magnet blocks listed within this document.

Any nonconforming item(s) shall be clearly identified, isolated, and placed in a secured location by the Contractor.

The Contractor shall document the nonconformance and send it to the BNL Technical Representative for review and disposition.

The Contractor shall email the required documentation listed within this document to the BNL Technical Representative immediately upon completion of the deliverable items as detailed in (Section 9).

Section 3: BNL Furnished Documents BNL will provide the following technical drawings as engineering specifications for manufacturing:

• Drawing LT-SR-MG-PMQH-3001: Hybrid Dipole Permanent Magnet Blocks

• Drawing LT-SR-MG-PMQH-4001: Hybrid Focusing & Defocusing Permanent Magnet Blocks

Section 4: Permanent Magnet Material Requirements The magnetic material of the PM blocks must meet the following magnetic parameters.

Table-1: Permanent Magnet Material Parameters (Nominal Reference Temperature: 20 ⁰C)

Description Value

Material Type Samarium Cobalt (Sm2Co17)

Remanent Flux Density (Br) 1.14 T Minimum, Range ± 0.02 T from average Br

Coercive Field (Hcj) 1740 kA/m, Minimum

Maximum Energy Product ((BH)max) 240 kJ/m3, Minimum

Section 5: Magnetization Direction Arrow To ensure precise orientation during hybrid magnet assembly, a magnetization direction arrow shall be permanently laser etched onto each block. The placement, sizing, and orientation of the laser-etched arrow shall strictly conform to the details as per the furnished drawings (Section 3).

Section 6: Tolerances All PM blocks must comply with the geometric and magnetization angle tolerances as specified in the supplied drawings (Section 3). ). If the required dimensions of the permanent magnet (PM) blocks can only be achieved by segmenting and gluing smaller blocks together, the contractor shall provide detailed drawings of the assembled geometry with the quotation.

Section 7: Progress Reporting The Contractor shall communicate technical and manufacturing progress to the designated BNL Technical Representative every three weeks. Reports shall be delivered via email or conference call, as mutually agreed upon.

Section 8: Quality Assurance Requirements The Contractor shall maintain a robust, documented quality management system complying with all terms of this SOW and the master BNL contract.

The Contractor shall provide a comprehensive end-item documentation package serving as objective evidence of complete compliance with the BNL contract requirements. The documentation package shall be fully traceable to the physical items supplied and must include all records specified in the Deliverables Section 9.

Section 9: Deliverables The Contractor shall deliver the following items to BNL:

• Hybrid Dipole PM Blocks: One hundred (100) pieces.

• Hybrid Focusing & Defocusing PM Blocks: Sixty-eight (68) pieces.

• Documentation: Electronic copies of standard dimensional inspection reports (with individual measured values for every single block traceable by serial identifier) and magnetic material test certifications matching Table-1 requirements. The documentation is to be received at BNL 1 week prior to shipping authorization.

• Shipping Authorization: The contractor will be given authorization electronically by BNL to ship the PM blocks following the review of the documentation.

• Packaging and Shipping: The PM blocks will be packaged in separate boxes to prevent chipping and demagnetization. The shipping container shall meet the requirements of transportation of strong (> 1 T) permanent magnets.

Section 10: Delivery Schedule All permanent magnet blocks identified in the Deliverables Section 9 of this document shall be delivered to BNL no later than (18) eighteen weeks after receipt of a BNL contract.

Delay Notification: Any schedule variances or potential delays shall be promptly and formally communicated in writing to the BNL Technical Representative.

Section 11: Proposal The supplier shall submit a proposal to BNL confirming their ability to meet all the requirements defined in this document and on the BNL furnished drawings. Each requirement that the supplier cannot meet shall be identified in the proposal with clarification as to what they can provide.
