- Description
- Description: This is a new amendment. This amendment extends the due date of this solicitation until January 22, 2007. To participate, vendors must submit a current offor. Award based on this solicitation is subject to availability of funds. (See FAR Clause- 52.232-18) The National Institute of Standards and Technology (NIST), has a requirement for Oriented Pyrolytic Graphite Neutron Filters to filter unwanted high energy neutrons from the detection system of the MACS neutron scattering spectrometer. The procurement covers twenty truncated rectangular pyramids of oriented pyrolytic graphite filters. Each of the twenty filters shall be denoted a filter block. The required physical dimensions and tolerances are provided in drawing 038-2453 rev 5. All interested parties must request this drawing by contacting: Tye Gibson Contract Specialist National Institute of Standards & Technology Acquisition and Logistics Division Phone: 301-975-3601 e-mail: tyegibson@nist.gov This requirement includes the following: LINE ITEM 0001 1) Vendor shall provide 20 truncated rectangular pyramids of accurately dimensioned oriented graphite block of specified chemical purity, density, mosaic distribution, and neutron transmission characteristics for MACS Scattered Beam Filter. Thickness: 50mm. Ref: Drawing 03802453 Rev-5. 2) Vendor shall provide pre-performance material sample (one month after receipt of order and prior to beginning of the production run). The pre-performance materials sample shall be representative of the filter material to be delivered. The pre-performance sample, can be a laminated structure, and shall have a thickness along the c-direction of 50 mm. The dimensions in both orthogonal directions perpendicular to the c-axis shall be between 20 mm and 50 mm. 3) Vendor shall provide a certified material analysis: Materials delivered under this order shall be accompanied by a certified materials analysis indicating the graphite and impurity content and the average mosaic distribution in the block as measured through X-ray diffraction. The government will perform at least two types of analysis on the pre-performance materials sample and will report the results to the vendor within 1 month of receiving the sample. The analysis will include: 1) Diffraction using 14.7 meV neutrons to determine the mosaic distribution. 2) Measurement of the neutron transmission along the c-axis as a function of neutron energy. Upon vendor request, the government will also carry out such measurements on material intended for inclusion in the product during the production phase. The results of such measurements will be reported to the vendor within 1 month of receiving the material. The total quantity of material to be analyzed in this fashion shall not exceed the total amount of material ordered. The Government analysis of material provide by the vendor does not relieve the vendor from their responsibility with respect to meeting the requirements set forth herein. The materials shall meet the following specifications: Materials Specifications Chemical Composition and Density: This specification ensures sufficient content of the desired oriented graphite majority phase.
