S-Band Thermionic RF Gun

SLAC National Accelerator Laboratory, operated by Stanford University for the Department of Energy, is seeking proposals for the procurement of S-Band Thermionic RF Guns for the SPEAR Linac facility. The solicitation requires one fully assembled RF gun as the base requirement, with an optional second unit that may be purchased later. The RF guns must meet precise technical specifications including a resonant frequency of 2856 MHz, operation at 3-7 MW power levels, beam/charge stability within 1%, and an unloaded quality factor greater than 12,000. Proposals will be evaluated based on technical compliance, past performance, schedule management, pricing, and financial standing, with technical factors weighted more heavily than price considerations. Clarification requests are due by July 1, 2025, and complete proposals must be submitted by July 11, 2025, at 4:00 PM Pacific Time, remaining valid for 90 days after submission.

This procurement does not utilize any set-aside designations and is open to all qualified vendors who meet the registration and documentation requirements. No incumbent contractors or current service providers are identified in the solicitation materials. While specific contract values or budget ranges are not disclosed, vendors must provide detailed pricing information along with their technical proposals and required certifications including Buy American Act compliance. The earliest requested delivery date is August 1, 2026, or sooner, indicating a timeline of approximately 13 months for manufacturing and delivery. The place of performance is West Menlo Park, California, where the SLAC National Accelerator Laboratory facility is located, and vendors must be registered in the System for Award Management (SAM) and provide Dun and Bradstreet reports as part of their qualification requirements.
