E-MAIL: Ann E. Bronson, ann.e.bronson1@jsc.nasa.gov. NASA/JSC plans to issue a Request for Offer (RFO) for the procurement of two proportional counters. The neutron insensitive proportional counter design will be based on the 2-inch detectors recently fabricated for the Space Station Equivalent Proportional Counter (TEPC) dosimetry system but will have approximately the dimensions of the "1 inch" detectors used in a recent shielding experiment on the Space Shuttle. The Contractor shall develop counters, one with sensitivity to both neutrons and charged particles, and the other to just charged particles. This approach should allow the separation of charged particle and neutron contribution of the dose and dose equivalent. The counters must be suitable for certification for Shuttle Flights. NASA/JSC intends to purchase the items from Dr. Les Braby, of Texas A&M University, College Station, Texas. The proposed vendor is the only one currently able to develop these types of devices. Dr. Braby has the capability and can provide the required expertise, as he was the original designer and developer of such detectors. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. See Note 22. An Ombudsman has been appointed. See Internet Note "B". Interested firms have 15 days from the publication of this synopsis to submit in writing to the identified point of contact, 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 the 15 days or without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government to not compete this proposed effort 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 qualified responsible sources may submit an offer which shall be considered by theagency.
