A -- DEVELOPMENT OF A SEALED, WATER CALORIMETER SOL 53SBNB760255 DUE 080197 POC Trena N. Bercaw, (301) 975-6324/Fax (301) 963-7732 WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contracts@nist.gov. The National Institute of Standards & Technology has a requirement for the construction of a sealed, water calorimeter for use in the dosimetry of ionizing radiation beams (e.g. Co-60 and accelerator-produced high energy photon beams) both vertically and horizontally directed. This work shall be based on the published developments of S. Domen, recognized internationally as the benchmark for the direct realization of absorbed dose to water for ionizing radiation beams. It is the intent of the government to negotiate only with The University of Texas Southwestern Medical Center, Radiation Oncology Department, as the only source reasonably available to satisfy the needs of this agency, in accordance with FAR 13.106-2(a)(5). The University of Texas has on staff Dr. Kenneth Gall, who is an expert in the dosimetry of ionizing radiation used in cancer therapy. Dr. Gall has worked directly with Steve Domen and is uniquely familiar with the concepts, design, fabrication and use of the required sealed water calorimeter. The period of performance for this requirement is from date of award through September 30, 1998. The Government intends to issue a Time and Materials purchase order for this requirement. Interested persons may identify their interest and capability to respond to the requirement or submit a quote. This notice of intent is not a request for competitive quotations. However, all quotes received by the response date 8/1/97, will be considered by the government. A determination by the Government not to compete this proposed contract based upon responses to this notice is solely within the discretion of the government. Information received will be considered solely for the purpose of determining whether to conduct a competitive procurement. No solicitation package is available. See Numbered Note 26. (0205)
