To all Potential/Interested Suppliers, Brookhaven Science Associates, LLC (herein known as “BSA”), operator of Brookhaven National Laboratory (BNL) under a Prime Contract with the U.S. Department of Energy (DOE), is seeking expressions of interest from firms regarding the design, manufacture, inspection, testing, documentation, and delivery of high-current power-supply systems for the Electron-Ion Collider Hadron Storage Ring as outlined in the following attachments:

Attachment A- Statement of Work for the HSR Main Arc Dipole and Quadrupole Power Supplies Attachment B- Technical Specification for the HSR Main Arc Dipole and Quadrupole Power Supplies Attachment C- BNL-QA-101

Please note that this is an RFI/Sources Sought notice, not a Request for Proposal, and no solicitation exists at this time.

This RFI is for informational and planning purposes only and is not to be construed as a commitment by the U.S. Government, nor will the U.S. Government pay for information received. The information from this notice will help the Department of Energy (DOE) Office of Basic Energy Sciences (BES) survey available resources.

Background:

The Electron-Ion Collider Project will design, construct, and install accelerator hardware for a new electron storage ring and electron injector and will modify the existing hadron ring to support electron-ion collisions. The Hadron Storage Ring will include superconducting main arc dipole and quadrupole magnets connected in series circuits. BSA anticipates procuring two high-current power-supply systems for the hadron storage ring:

• Model A for the HSR main arc dipole circuit

• Model B for the HSR main arc quadrupole circuit

The systems will provide precisely regulated, ramped current to superconducting magnet loads. Each system is expected to include the main power supply, quench-protection equipment, current measurement and regulation equipment, programmable controls, local operator interfaces, cooling-water interfaces, protective interlocks, and associated instrumentation.

The equipment must safely control high-current magnet circuits with substantial stored energy. The technical requirements include two-quadrant operation, high-accuracy current regulation, redundant quench protection, magnet-energy extraction interfaces, ground isolation, water-cooled power components, PLC-based controls, BNL control-system interfaces, and extensive equipment protection and diagnostics.

The anticipated supplier scope includes engineering, detailed design, analysis, manufacturing, assembly, software and firmware development, factory testing, documentation, packaging, delivery, and potential commissioning support at BNL. Formal preliminary and final design reviews are expected before production.

Please provide the following information:

2) Does your company have experience obtaining an NRTL certification for power supplies? Identify the NRTL organizations with which you have worked.

3) Are there technical or commercial obstacles to using NRTL-listed or NRTL-recognized components throughout the equipment? Identify any major components that would likely require special evaluation or acceptance.

4) What schedule and approximate cost allowance should BSA anticipate for an NRTL field evaluation of each completed system?

5) What long-term technical support, field service, remote diagnostics, repair, training, and refurbishment services can your company provide?

Schedule & Cost:

1) Can your company support formal preliminary and final design reviews before authorization to begin production? Describe the typical maturity of drawings, analyses, bills of material, software descriptions, test plans, and manufacturing plans available at each review.

2) What is the estimated total duration from contract award through engineering, PDR, FDR, material procurement, manufacturing, factory testing, and delivery?

3) Does your company have the production capacity to manufacture Model A and Model B concurrently?

4) What are the primary cost drivers (material, machining, testing, assembly, shipping, etc.)?

Provide rough percentages or ranged for each.

Logistics & Delivery:

1) What are the anticipated operating and shipping dimensions and weights of each major assembly? Identify any equipment that must be divided into shipping sections.

2) Are there any standard end item documents not identified above? If so, please list them.

3) Is your company able to provide qualified personnel to visit Brookhaven National Laboratory in

Upton, New York, to support installation, assembly, connection, inspection, startup, testing, and commissioning of the power-supply systems? If yes, describe the proposed scope of support, required BNL resources, estimated staffing and duration for this.

4) What warranty period would your company normally provide for equipment of this type, and when would the warranty period begin?

5) Identify any technical requirements that are expected to have a significant effect on cost, schedule, manufacturability, or technical risk.
