UHV Pump Cart

NIST-SS25-39 6695 / 334516 Title:? UVH Pump Cart BACKGROUND The NIST Sensor Science Division is responsible for advancing the measurement science, standards, and applications for sensing optical power, temperature, humidity, pressure, vacuum, flow, and related physical phenomena to support U.S. industry and trade. Our laboratory performs measurements and calibrations using cryogenic magnetic and optical detectors, and we operate a number of high vacuum chambers and cryostats for these experiments.

The ultra-high vacuum (UHV) pump cart to be purchased will be used to bring a chamber to UHV in order to reach the cryogenic operating temperatures of the highly sensitive infrared detectors to be tested. SSD requires a UVH pump cart to bring a test chamber to operating conditions for superconducting nanowire single photon detectors (SNSPD) for an upcoming infrared detector test program at the Low Background Infrared facility.

NIST has a need for an UVH Pump cart that meets or exceeds the following draft minimum specifications: The Contractor shall provide the following one (1) ultra-high vacuum pump cart that meet the following minimum specifications: Must consist of a turbomolecular pump, backing pump, pressure gauge, readout, and all interconnections The turbomolecular pump must achieve an ultimate pressure <10-8 hPa The backing pump must be of the dry, scroll pump variety The backing pump must achieve <3x10-2 hPa by itself The backing pump must have a pump rate of >100 L/min The pressure gauge must function over 10-8 hPa to 500 hPa or wider with a built-in display The system should be on a cart for mobility around a typical lab setting The system should plug into standard 120V, 60 Hz NEMA connection HOW TO RESPOND TO THIS NOTICE In responding to this notice, please DO NOT PROVIDE PROPRIETARY INFORMATION.

Please include only the following information, readable in either Microsoft Word 365, Microsoft Excel 365, or .pdf format, in the response.

Whether your company is an authorized reseller of the product or service being cited and evidence of such authorization.

Identify any aspects of the description of the requirements in the BACKGROUND section above that could be viewed as unduly restrictive or create unnecessary barriers that adversely affect your firm’s ability to fully participate in a procurement for such services and explain why. Please offer suggestions for how the requirements could be organized or structured to encourage the participation of small businesses.

For the NAICS code Indicate whether your company is (a) a small business or (b) other than small business. See the Table of Small Business Size Standards and the associated .pdf download file for small business size standards and additional information. If you believe the NAICS code listed in this notice is not the best NAICS code for the type of product addressed in this notice, identify an alternative NAICS code that you believe would be more appropriate for the planned procurement.

If your firm has existing Federal Supply Schedule contract(s) or other contracts for products or services against which the Department may be able to place orders, identify the contract number(s) and other relevant information. Describe your firm’s experience (as a prime, subcontractor, or consultant) providing the products or services described in Background section. Provide any other information that you believe would be valuable for the Government to know as part of its market research for this requirement.

Please let us know if you would like to engage to get a better understanding of the requirement or need additional information about the Government’s requirement for the products or services described in the Background section.
