Precision Aperture Fabrication – DSG-1002

A subcontract has been issued for the fabrication of a precision aperture designated DSG-1002, requiring advanced manufacturing techniques to achieve an ultra-smooth surface finish of 1nm RMS through plasma polishing. The component must strictly adhere to dimensional tolerances and clear aperture requirements as defined in the associated engineering drawings, ensuring it meets the high-performance standards necessary for precision optical or scientific applications. The work is to be performed at a facility with a zip code of 94025, aligning with the operational footprint of the SLAC National Accelerator Laboratory, a Department of Energy contractor responsible for overseeing this procurement. The solicitation was posted on April 30, 2026, with a response deadline of May 15, 2026, indicating a tight turnaround for qualified subcontractors to submit proposals. The NAICS code 332813 identifies the work as precision metal manufacturing involving specialized fabrication processes. While no set-aside classification or point of contact details are provided, the contract is explicitly categorized as a subcontract, implying it supports a larger project under the DOE’s purview. The technical demand for nanometer-scale surface quality suggests this aperture is critical for applications where surface purity and geometric precision directly impact system performance, such as particle beam instrumentation or high-resolution imaging systems.
