66 -- ROTATING ANODE X-RAY SOURCE SOL 52SBNB7C1147 DUE 052197 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, Contract@nist.gov. The National Institute of Standards and Technology (NIST) has a requirement for a rotating anode x-ray source (RAXS), which shall provide a high intensity x-ray beam for x-ray diffraction studies. It shall include a tube housing which can be mounted on the horizontal surface of an optical bench providing two x-ray beams which can be parallel to the table top. The rotation axis of the anode shall be convertible from being either perpendicular to the table top, to provide an x-ray beam which is 10 mm high (line focus), or parallel to it providing a beam which is .5 mm high (point focus). The anode assembly shall include a copper anode, a direct drive, ceramic bearings and magnetic seals. Vibrational stability of the x-ray beam shall be better than 2 microns. Evacuation of the anode chamber shall be provided by a turbo-molecular pump mounted directly to the anode housing . The remote generator shall utilize high frequency technology and provide a total power of 18kW. The operation of the system shall be by means of an integrated control panel. Delivery is required within 120 days after award of contract. The FOB Point shall be Destination, Gaithersburg, Maryland. All responsible sources may submit an offer. Please fax, mail or e-mail requests for a solicitation package. (0107)
