STATEMENT OF WORK

Pin Well Detector and Electronics

I. BACKGROUND INFORMATION

The NIST, Physical Measurement Laboratory, Ionizing Radiation Division, Radioactivity Group maintains the national standard for radioactivity. The purchase of equipment capable of making 4π gamma-ray measurements provides an alternative method for primary standardization of certain difficult-to-measure radionuclides that decay by electron capture. Electron capture (EC) is a type of radioactive decay that does not produce high-energy beta- or alpha- particles, which are generally easy to detect and count with high efficiency. Instead, the radiations associated with EC are low-energy X rays, medium-energy gamma rays, and/or Auger electrons, which are harder to quantify with the methods currently used by the Radioactivity Group. The Radioactivity Group seeks to acquire a new pin-well detector to complement the existing suite of instruments currently in use in its laboratories.

Purpose/Objective: The Radioactivity Group seeks to acquire a new Pin Well Detector to complement the existing suite of instruments in its laboratories and extend its capabilities for 4π gamma-ray measurements, providing an alternate method for the primary standardization of certain difficult-to-measure radionuclides that decay by electron capture. This will enable us to expand our SRM catalog to include several EC nuclides used as radiotracers in medical and environmental research, as well as calibration sources for photon detectors.

II. SCOPE

This requirement is for a Brand Name Only Mirion Technologies pin well detector system. The Contractor shall deliver one (1) turnkey pin-well detector system, including an integrated photo-multiplier tube (PMT), cabling, preamps, connections, etc., inclusive of FOB Destination delivery, warranty, technical drawings of the detector, data acquisition and data analysis software, and the line items listed in the Minimum Requirements.

III. MINIMUM REQUIREMENTS

The Contractor shall provide a system that meets all technical specifications 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, which are 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.

IV. DELIVERABLES

Standards of Acceptance: Acceptance is based on delivery and once installed, a successfully completed measurement, and no manufacturers’ defects observed. The test will be performed by NIST researchers within thirty (30) business days of installation. Installation will be completed by NIST.

V. PERIOD OF PERFORMANCE/LEAD TIME

Delivery shall be within 120 days after receipt of award.

VI. DELIVERY TERMS

Delivery shall be F.O.B Destination and shall occur in accordance with the delivery due dates provided in the above table.

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:

National Institute of Standards and Technology Shipping and Receiving 100 Bureau Drive, Building 301 Gaithersburg, MD 20899

VII. INSPECTION & ACCEPTANCE

In addition to the inspection and acceptance terms articulated in FAR 52.212-4, the Government reserves the right to conduct performance tests and evaluations as defined below to verify specified system performance. Such tests and evaluations, if performed, shall be conducted within the environment in which 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.

Performance Tests:

1. Proper Operation Test – The test shall be completed by the NIST TPOC within thirty (30) business days of delivery, excluding federal holidays, using a series of NIST-prepared radioactive sources. The test shall verify the proper operation of the system, the dead-time correction, data acquisition, data analysis and validation of operational parameters. The extended inspection and acceptance period is required to allow the system to acclimate and for NIST personnel to prepare the sources and perform the tests.

NIST may choose at its discretion to forego this part of acceptance testing.

A visual inspection of the equipment will be performed by the NIST TPOC to identify surface defects or any form of indication that any equipment 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 equipment due to defects and/or nonconformance. The vendor is responsible for latent defects discovered any time after final inspection. However, the extent of its liability shall be prorated over the useful life of the equipment.

Ownership of the equipment shall transfer to NIST upon acceptance by the Government.

VIII. WARRANTY

The contractor shall warranty the entire system for a period of a minimum of one year after acceptance of the equipment and shall be in accordance with the terms in FAR 52.212-4.

IX. PAYMENT SCHEDULE

Advance payment is not authorized. The Contractor must invoice in arrears according to the 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 and COR of fully installed system, AND

1. After the successful completion of the testing requirements set forth in this document under section set forth in this document.

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 the vendor’s response to the RFQ for consideration.
