66 -- INFRARED LABORATORIES CRYOSTAT SOL NB814904081BJ DUE 022599 POC BJ Roberts, Purchasing Agent, (303) 497-3799, Fax (303) 497-3163 E-MAIL: NOAA; MASC Acquisition Management, Barbara.Roberts@noaa.gov. The National Institute of Standards & Technology (NIST) is seeking to purchase a liquid helium cryostat. An Adiabatic Demagnetization Refrigerator (ADR) that has been previously designed and built by NIST will be installed in the cryostat, and the entire system will be installed on a scanning electron microscope. Because of the need to have interchangeability between this cryostat and existing cryostats at NIST, the design must be completely mechanically compatible with existing hardware Detailed drawings of the cryostat can be made available upon request. Requirements are 1)The cryostat must be less than 30 inches in height and 20 inches in diameter. 2)It must weigh less than 150 pounds. 3)The vacuum space between 4K and 300K must have at least 0.75 inches of space along the length of the cryostat for electrical wiring and mechanical connections. Details of electrical rotary feedthrough hole requirements at 4K, 77K and 300K must be followed and can be made available. 4)The cryostat must have a cavity of approximate dimensions 6 inches diameter and 10 inches depth to install an ADR. The cryostat must be able to support the weight of the ADR, 40 pounds, at the 4K stage. 5)Two vacuum feedthroughs shall be available near the location of the 4K stage. Mechanical design must allow for radiation shields to be installed at 77K and 4K at the location of the feedthroughs. Mechanical design must follow NIST design. Interested sources proposing to supply an equivalent system must submit a written qualification statement clearly establishing capability to meet the above requirements with 15 days from the date of the synopsis. In the absence of other qualified sources, it is the intent of the Government to negotiate a sole source contract under the authority of 41 U.S.C.253(c)(1) with Infrared Laboratories, of Tucson, Az as this source is considered to be the only responsible source and no other items will satisfy agency requirements. This procurement is being conducted per FAR Part 13, Simplified Acquisition Procedures (NTE $100,000). This synopsis is issued for information only. No competitive solicitation is planned. Information submitted in response to this notice will be used solely to determine whether or not use of competitive procedures to fulfill this requirement would be in the Government's best interest and must address qualifications pertinent to this requirement. No RFQ is available. All technical questions shall be addressed to John Martinis at NIST 303 497-3597. Posted 02/10/99 (D-SN297227). (0041)
