A -- GEOMETRICAL MODELING AND RADIATION TRANSPORT SOL 8-1-9-ES-C4109 DUE 080999 POC Carlos M. Smiley, Contracting Officer, Phone (256) 544-0355, Fax (256) 544-8656, Email carlos.smiley@msfc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/MSFC/date.html#8-1-9-ES-C4109. E-MAIL: Carlos M. Smiley, carlos.smiley@msfc.nasa.gov. NASA/MSFC plans to issue a Request for Quotation (RFQ) to perform geometrical modeling and radiation transport calculation for determining the radiation dose and energy deposition associated with the loss of confinement of antiprotons contained in a penning trap. Work shall utilize a mechanical and material description of the penning trap container and a source description of primary antiprotons and secondary particlae, which MSFC will make available to the contractor. The contractor will incorporate a simple geometrical description of the container together with an external shield of variable thickness surrounding the container into the coupled high energy transport code (HETC) -- electron gamma shower (EGS) code and perform radiation transport of the source particles to points external to the shield. The object of the calculation is to determine a shielding configuration that will maintain an acceptable dose exposure level at the external surface of the shield. The required final product shall be a report containing dose and energy deposition in a tissue equivalent detector at various distance external to the penning trap container and shield for various shield thicknesses. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/MSFC intends to purchase this service from Science Applications International Corp.(SAIC), Inc. 1410 Spring Hill Road, McLean, VA 22102. The authority under which these services will be procured is FAR 13.106 (2)(b), Other Than Full and Open Competition because of the urgency and unique characteristics of this requirement, no other contractor can provide it in the timely manner that is required. The Government does not intend to acquire a commercial item using FAR Part 12. See Notes 22 and 26. Interested firms have until August 9, 1999 4:00 PM CST 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 August 9, 1999, 4:00 PM CST 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. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
