Optional Additional Photon Stopper Holder Fabrication

The contract allows for the potential fabrication of up to four additional photon stopper holders if SLAC exercises unpriced options identified as CLINs 002 through 005, with no change to the technical specifications established in the base order. This subcontract is structured to provide flexibility in procurement, enabling SLAC to scale production based on operational needs without renegotiating technical requirements. The effort falls under the NAICS code 332999, indicating other fabricated metal product manufacturing, and is managed by SLAC National Accelerator Laboratory, a Department of Energy contractor. The solicitation was posted on May 8, 2026, with responses due by June 5, 2026, indicating a standard window for potential offerors to submit proposals. The place of performance and point of contact details are unspecified, suggesting the work may be performed at various approved contractors’ facilities under SLAC’s oversight. Although no set-aside preferences are indicated, the contract remains open to eligible subcontractors capable of meeting the technical standards of the original photon stopper holder design. All activities are subject to SLAC’s authority and funding decisions under the Department of Energy’s broader mission support objectives.
