30 kV 50 ohm attenuator

The Department of Energy Office of Science is soliciting proposals for the design, manufacture, and testing of two specialized 50-ohm attenuators for the Electron-Ion Collider (EIC) project at Brookhaven National Laboratory. These high-voltage attenuators will function as matched loads for a strip-line kicker operating at ±30kV, with demanding technical specifications including a maximum peak power of 20 MW, 1 Hz repetition rate pulsed operation, and bandwidth from DC to 1 GHz. The procurement requires contractors to comply with ISO-9001 quality management standards and deliver comprehensive documentation including program plans, technical reports, manufacturing plans, and design review reports. The attenuators must operate within strict environmental parameters (18-35°C, 90% relative humidity) and meet specific electromagnetic compatibility standards including IEC 61000-6-2 and IEC 61000-6-4. The solicitation was posted on June 27, 2025, with proposals due by July 13, 2025, providing bidders a tight 16-day response window.

This procurement does not utilize any set-aside designations and is open to all qualified contractors. The work requires completion within 16 weeks of contract award, with the attenuators to be delivered and installed at the Brookhaven National Laboratory facility in Upton, New York. The devices must be capable of accurately measuring pulse characteristics with 7-nanosecond rise and fall times and 40-nanosecond flattop in an ionizing radiation environment, utilizing air cooling and transformer oil insulation. The solicitation emphasizes value engineering opportunities, encouraging contractors to propose improvements in performance, reliability, and cost-effectiveness while meeting the stringent technical requirements. The contractor will be subject to ongoing oversight by Brookhaven Science Associates through design reviews, testing witness procedures, and configuration management protocols throughout the 16-week delivery timeline.
