NIST Requirements Document Ultra-high vacuum pump cart

I. 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.

II. Scope We require an ultra-high vacuum (UHV) 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.

III. Minimum Requirements The system shall meet or exceed the minimum requirements identified below. All items must be new. Used or remanufactured equipment will not be considered for award. Experimental, prototype, or custom items will not be considered. The use of “gray market” components not authorized for sale in the U.S. by the Contractor is not acceptable. All line items shall be shipped in the original manufacturer’s packaging and include all original documentation and software, when applicable.

The Contractor shall provide the following one (1) ultra-high vacuum pump cart that meet the following minimum specifications:

1) Must consist of a turbomolecular pump, backing pump, pressure gauge, readout, and all interconnections

2) The turbomolecular pump must achieve an ultimate pressure <10-8 hPa

3) The backing pump must be of the dry, scroll pump variety

4) The backing pump must achieve <3x10-2 hPa by itself

5) The backing pump must have a pump rate of >100 L/min

6) The pressure gauge must function over 10-8 hPa to 500 hPa or wider with a built-in display

7) The system shall be on a cart for mobility around a typical lab setting

8) The system shall plug into standard 120V, 60 Hz NEMA connection

9) The inlet shall be DN 40 ISO-KF, either directly on the pump or with the use of an adapter. Note that the pressure test in item 2) can be met using a different standard flange but that in this case the system must also include an adapter to DN 40 ISO-KF to enable its use when needed.

IV. Deliverables

Standards of Acceptance: The NIST TPOC or COR shall review each deliverable and respond with an acceptance or request for revision email to the Contractor Point of Contact (POC) within fourteen (14) days of receipt of deliverable. This section applies to deliverables which must be reviewed and approved for acceptances (draft plans, drawings, etc.)

V. Place of Performance All deliverables shall be delivered to NIST in Gaithersburg, Maryland in accordance with Section VI. Delivery Terms.

VI. Period of Performance/Lead Time Delivery shall be within 100 days after receipt of award (ARO).

VII. Delivery Delivery shall be FOB Destination (or equivalent terms, such as INCOTERMS Delivered Duties Paid) are required and shall occur not later than (NLT) 100 days ARO.

FOB Destination means: The contractor shall pack and mark the shipment in conformance with carrier requirements, deliver the shipment in good order and condition to the point of delivery specified in the purchase order, be responsible for any loss of and/or damage to the goods occurring before receipt and acceptance of the shipment by the consignee at the delivery point specified in the purchase order; and pay all charges to the specified point of delivery. The contractor shall deliver all Line Items to:

The National Institute of Standards and Technology 100 Bureau Drive Attention: Grant Teply 221/B265 Gaithersburg, MD 20899 VIII. Inspection and Acceptance In addition to the inspection and acceptance terms articulated in 52.212-4, the Government reserves the right to perform such performance tests and evaluations as defined below to verify specified system performance. Such tests and evaluations, if performed, shall be conducted within the environment that the system is to be operated. The Contractor has the right to be present during the tests and evaluations, if performed, at the Contractor’s expense.

The UHV pump cart should be tested by the manufacturer prior to shipping to ensure that it functions properly. Upon receipt at NIST, the system will be inspected for damage. If there is no damage, the UHV pump cart system will be blanked off and pumped out to the required <10-8 hPa, which should be achieved within an hour. If there is no damage and the test is passed, NIST will accept the instrument.

The Government will test, inspect, and accept the equipment onsite within fourteen (14) business days of the receipt of the UHV pump cart. A visual inspection of the UHV pump cart will be performed by the NIST TPOC to identify surface defects or any form of indication that the UHV pump cart was damaged during transport to NIST. The Government shall have sole discretion to require repair or replacement of damaged and/or nonconforming supplies at no cost to the Government. The Government at any time prior to acceptance shall reject the UHV pump cart due to defects and/or nonconformance.

IX. Warranty The contractor shall warrant the entire system for a period of a minimum of 1 year after receipt of the equipment and shall be in accordance with terms in FAR 52.212-4

X. Payment Schedule The Contractor shall be paid, in accordance with Net 30-day payment terms, upon receipt and acceptance of a proper invoice, in accordance with the following schedule:

1. 100% after installation and acceptance by the TPOC of fully installed system.

2. The Government anticipates inspection will occur upon:

a. After the testing procedures set forth in this document have been completed
