- Description
- This is a SOURCES SOUGHT SYNOPSIS for market research purposes. The National Institute of Standards & Technology (NIST) is seeking Contractors with expertise in the fabrication and building of a custom Fourier transform infrared spectrometer for use in a high-vacuum, (10^-9 Torr) cryogenic (15K) environment in accordance with the information provided herein.***Detailed information on the Contractor?s experience and expertise in building the same or similar equipment must be sent to the National Institute of Standards and Technology, Acquisition and Logistics Division, Attn: Carol A. Wood, Contract Specialist, 100 Bureau Drive, Mail Stop 3571, Gaithersburg, MD 20899-3571. Submission must be received by 3:00 p.m. local time on December 2, 2003. Original submissions are required.*** Contractors shall identify their business size, (small, small-disadvantaged, hub-zone, large etc.) in accordance with North American Industry Classification System (NAICS) Code 334516, Analytical Laboratory Instrument Manufacturing; the Small Business Size Standard is 500 employees. ALL BUSINESS SIZES ARE WELCOME TO RESPOND TO THIS SOURCES SOUGHT NOTICE.*** THIS IS NOT A REQUEST FOR PROPOSALS ? IT IS FOR MARKET RESEARCH PURPOSES ONLY.*** DESIGN AND BUILD A BXR II CRYOGENIC-FT The BXR II is an infrared (2 ? 30 micrometers wavelength) radiometer that is currently being designed at NIST. The instrument is a high vacuum, cryogenic (15 K) device that incorporates a precise power measurement mode of operation and a high spectral resolution mode of operation. At this time a large fraction of the BXR II design has been finalized. In the current design, the BXR II samples a 7 cm diameter beam of infrared radiation and telescopes it down to approximately 1.5 cm. A field limiting aperture limits the divergence in the 1.5 cm beam to 5 mrad maximum, however it will typically be less than 1 mrad. In the precision power mode of operation the beam is directed towards a set of filters used for filter based radiometry. In the high spectral resolution mode of operation the beam is first directed through a proposed Cryogenic Fourier Transform (Cryo-FT) interferometer before passing through the filter based radiometer portion. At this time the Cryo-FT has only been designed in very rough terms and has been assigned a volume in the BXR II for its future existence. A rough drawing of the current design configuration of the BXR II is available as an MS Word document, with the file name BXR II Design Mod7.doc. (E-MAIL REQUESTS FOR THIS DOCUMENT MUST BE SENT TO CAROL.WOOD@NIST.GOV).****DESIRED OUTCOME OF CONTRACT FOR CRYOGENIC-FT DESIGN AND BUILD: The ultimate outcome any subsequent request for proposal would be to build a Cryo-FT that is fully compatible with the BXR II and meets the following optical requirements: spectral range of 7 ? 14 micrometers minimum with a single beam splitter, spectral range 4 ? 15 micrometers with a single beam splitter preferred, spectral range of 2 ? 30 micrometers with interchangeable beam splitters, resolution of 1 wavenumber with lower resolution acceptable, beam diameter of 1.7 cm with no central obstruction, can accept and function to all specifications with a 5 mrad full cone divergent beam, uses a reference laser with wavelength shorter than 1 micrometer, reference laser and dyanamic alignment lasers (if needed) must not obstruct 1.7 cm central beam path, scan rate must be greater than 5 scans/minute, modulation efficiency of 20 % approximately, and beam redirection must be less than 0.3 arcmin during mirror scan.***Compatibility with the BXR II must be achieved in at least these following areas: VACUUM/CRYOGENIC - All components must be made of material suitable for high vacuum, and all components must be fully operational at 15 K. All structural components and metallic optical components must be Aluminum Alloy 6061-T651 and heat treated for stress relief per military specification MIL-H-6088G. MECHANICAL/OPTICAL ? The Cryo-FT must fit within its allocated volume within the BXR II, as shown in the attached drawing. The Cryo-FT must also have a mounting system that is compatible with the BXR II which must be designed and confirmed with NIST personnel involved in the project. The input and output beams for the Cryo-FT must be at the precise locations and directions shown in the drawing and the total path length through the Cryo-FT, from the first BXR II moveable mirror surface to the second BXR II movable mirror surface, must be 17.000? ? 0.005?. A suitable example of a FT path length is shown in the drawing. THERMAL MANAGEMENT - All Cryo-FT components within the BXR II will be maintained in a 15 K environment. Heat output of these components should be kept to a reasonable minimum. Moving parts and such as the scanning and alignment mirrors should be the primary contributors to heat generation and it is anticipated that such devices would dissipate less than 0.5 W total during continuous operation. Heat strapping shall be applied where possible and no elements should exceed 30 K during continuous operation. Thermal management issues shall be reviewed by NIST personnel during the design stage before the final system is implemented.***The delivered system shall be a complete and functional system. This shall consist of at least a vacuum-cryogenic Michelson interferometer that is to be placed into the BXR II, control hardware for the interferometer and software for remote control, data acquisition, spectra display and diagnostic work. Note that delivery of a successful instrument will be weighed heavily over delivery time.
