Requests for copies of a solicitation will not receive a response. This Notice is for planning purposes only and is not a Request for Proposal or Request for Quotation or an obligation on the part of the National Institute of Standards and Technology (NIST) for conducting a follow-on acquisition. NIST does not intend to award a contract on the basis of this Notice, or otherwise pay for the information requested. No entitlement or payment of direct or indirect costs or charges by NIST will arise as a result of submission of responses to this Notice and NIST use of such information. NIST recognizes that proprietary components, interfaces and equipment, and clearly mark restricted or proprietary components, interfaces and equipment, and clearly mark restricted or proprietary data and present it as an addendum to the non-restricted/non-proprietary information. In the absence of such identification, NIST will assume to have unlimited rights to all technical data in the information paper. NO SOLICITATION DOCUMENTS EXIST AT THIS TIME. Requirement The National Institute of Standards and Technology (NIST), Material Measurement Laboratory (MML), Materials Measurement Science Division (MMSD-643) requires an X-ray diffractometer instrument with a silver X-ray source and optimized for measuring X-ray total scattering to support several NIST’s projects requiring the understanding of the local atomic order in materials and in situ studies of material processes. These projects include AI-assisted synthesis of metal-organic framework materials, high-throughput design of high-entropy alloys, additive manufacturing of metals and developing methods for determining the local structure of inorganic and hybrid materials. A silver X-ray source produces X-rays at a wavelength of 0.56 Å (k-alpha), and this allows accessing significantly larger values of the momentum transfer and a much deeper penetration of X-rays into inorganic matter compared to the more commonly available copper X-ray source. X-ray total scattering data includes the Bragg peaks, which reflect the average atomic arrangement, and a diffuse background, which contains information about the correlated deviations from this arrangement. Large values of the momentum transfer allow for the Fourier transformation of these data, yielding an atomic pair distribution function (PDF), which facilitates the determination of the local and nanoscale atomic order. Besides the short wavelength of the incident radiation, effective measurements of the total scattering require the instrument to be optimized for minimizing any parasitic backgrounds. The deeper penetration enabled by using the silver source permits in situ studies of material reactions using electrochemical or gas cells. NIST is seeking information on vendors who could potentially provide the following. X-ray Generator: Voltage and current settings must be continuously adjustable via software. X-ray Source: Conventional sealed x-ray tube.
