Quick Summary
The Department of Energy (DOE), through Oak Ridge National Laboratory (ORNL), has issued a Solicitation for the ORNL High Flux Isotope Reactor GP-SANS Polarizer. This opportunity seeks proposals for the fabrication and delivery of a complete polarizing cavity and magnetic housing assembly to upgrade the General-Purpose Small-Angle Neutron Scattering (GP-SANS) instrument. The enhancement will enable spin-resolved SANS measurements, facilitating studies of magnetic order and spin structures. There is No Small Business Set-Aside. Proposals are due July 24, 2026, at 5 p.m. EDT.
Scope of Work
This effort requires the fabrication, inspection, and delivery of a complete polarizing cavity and magnetic housing assembly for installation at the GP-SANS instrument. Key technical requirements, detailed in Attachment A, include specific dimensions, magnetic housing specifications, polarization levels (>=95% minimum), neutron beam transmission (>=30% minimum), vacuum compatibility (1.0x10^-3 Torr), and strict stray magnetic field limits (<=15 Gauss at 300 mm). The project also mandates electronic document submission, design drawings, CAD files, a final design review, a comprehensive Quality Assurance (QA) program, and detailed testing procedures covering magnetic casing, polarizer assembly, magnetic field strength, neutron testing, and dimensional inspections. A robust packaging and shipping plan is also required.
