STATEMENT OF WORK

Title: POLAR detectors Requesting Lab: National Institute of Standards & Technology (NIST) Center for Neutron Research (NCNR), Research Facility Operations (RFO) Group

BACKGROUND

The National Institute of Standards and Technology (NIST) Center for Neutron Research (NCNR) owns and operates a 20 MW test reactor called the National Bureau of Standards Reactor (NBSR). The NBSR is located on the NIST campus in Gaithersburg, Maryland, USA. The NBSR is a heavy water D2O-cooled and moderated reactor. The NCNR is in the process of building a state of the art polarizing cold neutron triple axis spectrometer for the study of solid state materials. Neutrons produced in the reactor are monochromated and collimated and directed to the sample under test. Neutrons scattered from the sample are analyzed by a multi blade crystal analyzer and diffracted into an array of neutron detectors for tabulation. These detectors will line the inside of the analyzer housing and will enable this instrument to simultaneously collect neutrons from a wide band of energies. The current design for the POLAR analyzer calls for 85 neutron proportional counters of 8 mm diameter and 150 mm active length to line the analyzer housing.

OBJECTIVE

This procurement will supply NCNR and the POLAR instruments with neutron detectors required to measure scattered neutron radiation.

SCOPE

The Contractor shall supply and deliver eighty-five (85) neutron proportional counters inclusive of FOB Destination delivery terms (or equivalent INCOTERMS) and 1-year warranty.

MINIMUM REQUIREMENTS

The Contractor shall submit a firm-fixed price quotation which meets or exceeds the requirements identified in this document. Offerors shall submit a quotation addressing the required specifications and shall provide descriptive literature, as required, to fully demonstrate how the proposed equipment will satisfy the requirements. All items shall be new. Used or remanufactured equipment will not be considered for award. Experimental, prototype, or custom items will not be considered. All line items shall be shipped in the original manufacturer’s packaging and include all original documentation and software, when applicable.

The Contractor shall draft and submit a Bill of Materials for all materials intended to be fabricated. The Bill of Material shall include current delivery lead times, cutsheets, specifications, wiring diagrams, and manuals for NIST to review and accept the proposed parts. COR approval for all items shall be received by the Contractor prior to procuring items for this project.

The Contractor shall provide contact information for its designated main point of contact/Project Manager (i.e., Work Phone, Cell Phone, and email).

Line-Item 0001 Description: Neutron Proportional Counters, including Contractor POC Information, and Bill of Materials Spec Sheet with Lead Time Quantity: Eighty-Five (85) Neutron Proportional Counters

A. Technical Requirements

a. Mechanical. The neutron proportional counters shall have an outer diameter of 8 mm and an active length of 150 mm (5.9055 inches). The tube body shall be stainless steel.

b. Electrical. The anode connection shall be a flying lead of a length at least 610 mm (24 inches)

c. Sensitivity. The target neutron sensitivity is 90% for 5 meV (4 Å) neutrons. The detection gas shall be 3He with CO2 and Ar quench gases.

B. Design Drawing

a. Drawing must include the tube and the cable, with the associated dimensions specified for each part. The initial drawing will be submitted to the NIST TPOC for review and approval. The Contactor must have NIST approval of the drawing prior to manufacturing the counters or it is at contractor risk.

DELIVERABLES

Contractor POC Document: No later than one (1) week ARO

One (1) final drafts No later than three (3) weeks after receipt of order.

Standards for Acceptance of Deliverables The NIST TPOC will provide written or electronic comments on each deliverable within Ten (10) calendar days from receipt of a given deliverable. The Contractor shall make any needed changes and resubmit the deliverable within Ten (10) calendar days from receipt of electronic or written comments from COR. The COR will provide written notification via email when a deliverable is accepted.

DELIVERY TERMS

F.O.B. Destination.

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.

WARRANTY

The manufacturer warranty for equipment is required. The Contractor shall warrant for one (1) year. All costs including parts, labor, travel, and other expenses necessary to perform repairs on warranty work will be the responsibility of the contractor at no additional cost to the government. Warranty is in accordance with terms in FAR 52.212-4. Warranty shall commence upon acceptance of the work by the Government.

PAYMENT SCHEDULE

Advanced payment is not authorized. Services shall be invoiced for in the arrears. The Contractor shall be paid in accordance with NET 30-day payment terms upon receipt and acceptance of a proper invoice. An invoice shall be submitted in accordance with the billing instructions provided in the purchase order and after the system has been accepted by the Government.

NOTE: Partial shipments and partial invoices will not be accepted, unless otherwise requested and accepted by the Contracting Officer prior to award offer. Proposed payment schedules shall be submitted with vendor’s response to the RFQ for consideration
