Statement of Work for the ESR D2 Dipole Magnets

SCOPE

This Statement of Work (SOW) will be the basis for the procurement of ESR D2 Dipole Magnets to be used at the Electron-Ion Collider (EIC) at Brookhaven National Laboratory (BNL) managed by Brookhaven Science Associates (BSA). This document outlines the Contractor’s responsibilities and obligations necessary for completing the requirements as set forth herein.

Background

The Electron-Ion Collider (EIC) is a Nuclear Physics facility being built at the United States (U.S.) Department of Energy’s (DOE) Brookhaven National Laboratory (BNL). The EIC will create intense beams of relativistic energy electrons and ions in opposing particle storage rings that will be brought into collision in a large experimental detector. This will provide insight into the internal structure of protons and neutrons and the gluelike force that holds them together.

Conventional beam line accelerator magnets will be used to bend and focus high energy and high intensity electron beams in the EIC Electron Storage Ring (ESR). The ESR “ring” will be located in the existing Relativistic Heavy Ion Collider (RHIC) tunnel. The ESR will have a beam line circumference of 3,830 meters (2.4 miles).

The ESR will store the polarized electron beam for the EIC particle collisions for hours at various energies, depending on the science program, from 5 GeV to 18 GeV. Therefore, the ESR dipoles, will operate at constant field/current. The magnets shall be fabricated with high quality laminated steel to provide high field quality. For production, there will be a requirement to shuffle the laminations from different heats to provide minimal differences in magnetic field strength from magnet to magnet because they are powered in a single series string.

APPLICABLE DOCUMENTS

In the event of a conflict between the Technical Documentation and this SOW, the Contractor shall immediately notify the BSA contract representative who shall in each instance determine which document takes precedence and advise the Contractor accordingly. Failure to notify BSA contract representative of a document conflict shall not relieve the Contractor’s responsibility to ensure full compliance to all requirements.

The following documents and drawings are an integral part of the SOW; the applicable revision level will be the latest that is in effect at the time of award:

REQUIREMENTS

In accordance with the technical specification, referenced drawings (drawing references includes the model file), and instructions as defined in this Statement of Work, the Contractor shall be responsible for designing, manufacturing, inspecting, testing, and delivering the ESR D2 Dipole Magnets.

The vendor will purchase all steel for D2 magnets totaling 1,068 tons. The steel will be stored under required conditions identified in Technical Specification EIC-MSG-SPC-010

Contractor and BSA Responsibilities

The BSA/EIC Engineering group is responsible for the magnetic analysis and core and coil design of the D2 dipole magnet to meet the ESR performance requirements and interfaces. The referenced specification control drawings and technical specification are the result of the magnetic design effort. The Contractor is responsible for the detailed magnet engineering design in accordance with the technical specification and drawings. The Contractor’s magnet design shall be reviewed and approved by the BSA technical representative in accordance with this SOW before proceeding with production of a first article production magnet.

First Article Magnet The Contractors are responsible for fabricating and assembling one (1) first article magnet that will verify the magnet’s conformance to this SOW, the technical specification, the referenced control drawings, the quality of the Contractor’s design and fabrication methods, and the conformance of the BSA/EIC magnetic design to the ESR performance requirements. The Contractors shall procure all materials and fabricate a first article magnet that shall be inspected and tested by the Contractors prior to shipping. BSA will inspect, test, and magnetically measure the first article magnet at no cost to the Contractors. After review of the inspection, test, and measurement results, the magnets will be approved for production in writing by the BSA technical representative.

Production Magnets The Contractors shall fabricate and assemble one hundred ninety-four (194) production magnets that will be inspected and tested by the Contractors prior to shipping. BSA will inspect, test, and magnetically measure the production magnets to verify the quality of each magnet at no cost to the Contractors. After review of the inspection, test, and measurement results the magnets will be accepted for installation by the BSA technical representative. The magnets will be installed by BSA. See the table below for the number of magnets per configuration.

Magnet Testing Requirements The magnets shall be inspected and tested by the Contractor at the Contractor’s facility, the Contractor’s subcontractor’s facility, or a pre-approved BSA collaborator prior to shipment, using the Manufacturing/Inspection/Test Plan defined in this SOW. The BSA technical representative retains the right to witness all inspections and tests. Final acceptance of the magnets shall take place following the successful completion of final testing and magnetic measurement at BNL. The time period for the final testing at BNL shall be within 90 days after receipt of the magnets at BNL.

First Article Acceptance BSA’s acceptance of the first article magnets is required prior to the production run. The first article shall be identified as such, including the contract, part number, and part name.

After BSA technical representative acceptance of first article magnets, all remaining magnets required by the Contract shall be produced by the Contractor and the Contractor’s suppliers using the same design, materials, processes, methods, and tooling that were used to manufacture the approved first article(s). Any changes must have prior written approval from the BSA technical representative.

Repairs

If failures occur or repairs are required to a magnet assembly or any component during manufacturing or testing that affects form, fit, function, reliability, safety, or interchangeability the process shall stop and the BSA technical representative shall be immediately notified. The BSA technical representative at their discretion may ask for retesting, additional review and evaluation to determine root causes, analyses of failure modes(s) or proposals for repair. Proposals for repair shall include adequate information for evaluating the repair, testing the effectiveness of the repair, and methods to prevent damage to the existing work. No proposed repair shall be initiated without approval of the BSA technical representative. No repair shall be considered successfully accomplished without inspection and written approval by the BSA technical representative. All repairs shall be at the expense of the Contractor. In addition, the Contractor shall not use nonconforming materials via use-as-is disposition without written approval from the BSA technical representative.

The results of all failure evaluations and analyses shall be documented and available for review by the BSA technical representative.

DELIVERABLES

The Contractor shall supply the following:

SCHEDULE

The following schedule is for planning purposes only. Schedule requirements set forth in the contract will take precedence.

VALUE ENGINEERING

The Contractor is encouraged to make recommendations for changes that might lead to improvements in performance, reliability, quality, safety, or reduction in cost. Simplicity in design and manufacture and an improvement in the performance and reliability beyond the requirements of this SOW and the technical specification are objectives which shall be considered in the dipole magnet design. Where it appears a substantial improvement in simplicity of design, performance, reliability will result from the use of materials, parts, and processes other than those specified, it is desirable that their use be investigated. When investigations point to advantages that may be realized, the recommendation for change shall be presented to the BSA technical representative for review.
