E-MAIL: Sandy Shin, Sangok.S.Shin.1@gsfc.nasa.gov. NASA/GSFC plans to issue a Request for Offer (RFO)5-12422-254 on a sole-source basis to the Canadian Commercial Corporation (CCC) for 100% subcontracting to EG&G Canada Ltd., for the acquisition of 36 Single Photon Counting Silicon Avalanche Photodiode Detector (APD) Modules. These modules will be incorporated into the Geoscience Laser Altimeter System (GLAS) to measure Earth atmospheric cloud and aerosols profiles. The successful single photon counting silicon APD must provide the following capabilities: photon detection efficiency greater than or equal to 55% detection wavelength of 532 nm, maximum count rate of 10 Mcounts/s, dark counts less than 500 counts/s, and a minimum operational lifespan of 3 years. NASA/GSFC intends to enter into a fixed price contract with the CCC for 100% subcontracting to EG&G Canada Ltd. which has a patented approach in the design of its single photon counting silicon APD detectors. This is the only design known to the Government to satisfy all minimum requirements. EG&G is the only manufacturer of the proposed single photon counting silicon APD detector capable of meeting the Government's minimum technical requirements (see the first paragraph) and a 24 month delivery schedule. The statutory authority is U.S.C. 2304(c)(1), Only One Responsible Source. This procurement is being conducted under the NASA MidRange Pilot Test Program approved by the Office of Federal Procurement Policy. See Numbered Note 26. Interested firms have 15 days from publication on the NAIS (or Commerce Business Daily (CBD) if over $500K) to submit their qualifications/capabilities. Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. Responses received after 15 days without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government not to compete this proposed contract, on a full and open competitive basis, based upon responses to this notice, is solely within the discretion of the Government. Firm date for receipt of offers will be stated in the RFO. All responsible sources may submit an offer which shall be considered by the agency.
