66 -- INTEGRATED DEWAR-INFRARED DETECTOR SYSTEM SOL NRMAP100000456MB DUE 060200 POC Michelle Bernal, Purchasing Agent, (303) 497-3983 or FAX (303) 497-3163 E-MAIL: NOAA; MASC Acquisition Management, Michelle.A.Bernal@noaa.gov. The National Oceanic & Atmospheric Administration(NOAA) has a requirement for an Integrated Dewar -- Infrared Detector System for the reliable and precise measurement of the flux of CO2 across the air-sea interface, with the following specifications: 1) Detect extremely small differences in the mole fraction of CO2 in dry air, namely differences of a few parts per billion in an ambient environment of 370 parts per million, when averaged over one hour. 2) An electro-optic analyzer system operating at liquid nitrogen temperature to meet the required sensitivity. 3) The system must consist of a pair of indium antimonide photo diodes each 1 mm in diameter and optical concentrators to sense the IR radiation transmitted through existing chemical cells situated on an optical table. 4) Two collimated beams of radiation at 4.25 micrometer and bandwidth 0.2 microns, with diameter 0.31", and separated vertically by 1.000" (centered) will be presented to the detector optics (light source has diameter 0.100", focal length of collimating lens is 2.5"). 5) The system cannot be sensitive to ship motion, which rules out the use of a rotating optical chopper wheel. 6) Must be possible to pump the liquid nitrogen reservoir to subambient pressure to solidify the nitrogen. 7) System must be capable of complete disassembly in the field. The Dewar will have a hold time of at least 24 hours. 8) The outer diameter of the dewar is approximately 10", to fit through a hole in the existing optical table. 9) The dewar has to be ungradable to make three additional CO2 analyzers with the same sensitivity, aligned at right angles to each other. This procurement is being conducted per FAR Part 13, Simplified Acquisition Procedures. You may submit your proposal by fax or by mail. Proposal must be received on or before close of business June 2, 2000.
