66 -- X-RAY GENERATING SYSTEM SOL 52SBNB7C1247 DUE 090297 POC Brenda K. Lee (301) 975-6394 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 high precision X-Ray Generating System. The system required shall be a high stability microprocessor controlled, 100kV constant potential, 4.2kW industrial X-ray system. In addition to the X-ray system, the Government requires two (2) copies of the operating manual, two (2) copies of the circuit drawings, (2) copies of the detailed dimensions & a drawing of the X-ray tube and a detailed statement of the standard warranty and terms. The X-ray system must provide maximum compatibility with our existing computer interfacing software and data acquisition and automation equipment. This system must offer a high-voltage cable compatibility with the NIST calibrated voltage divider, which will be an integral part of our calibrated x-ray system. The resulting absence of voltage and current interaction is of the highest importance for national standard calibration work, which requires stability and repeatability. The X-ray generating system shall be capable of 100 kV constant potential and at least 60 mA at 50 kV, have a rack-mounted microprocessor-controller, be uni-polar (negative polarity) and be rated for continuous duty operation. The mode of high voltage generation shall result in high stability and low ripple operation at maximum operating conditions. There must be no interaction between the high voltage and tube current, that is, the high voltage remains constant while the tube current is varied, and vice versa, within the x-ray tube parameters. Detailed specifications shall be provided in the solicitation. FOB Point shall be Destination, Gaithersburg, MD. Required delivery within 30 days from contract award. The contractor shall provide installation of the system within 30 days after delivery. All responsible sources may submit a proposal which will be considered by the agency. Request for solicitation package should either be mailed to the National Institute of Standards and Technology, Acquisition and Assistance Division, Building 301, Room B117, Gaithersburg, Maryland 20899-0001, or faxed to (301) 963-7732. All requests for the solicitation package must be in writing. Faxed proposals will not be accepted. (0237)
