Title: Dilution Refrigerator for TKIDs work Requesting Lab: PML 682.03

I. BACKGROUND INFORMATION

Purpose/Objective: The Neutron Physics Group (NPG) at NIST is working with the NIST Quantum Sensors Division to develop cryogenic Thermal Kinetic Inductance Detectors (TKIDs) for external charged particle detection, with the goal of installing these detectors on a cold neutron beamline at the NIST Center for Neutron Research (NCNR) for neutron physics experiments. This work requires the NPG to acquire a dry dilution refrigerator for initial prototyping and testing of TKIDs with small radioactive sources. This same dilution refrigerator will later be moved to a neutron beamline for a demonstration experiment.

II. SCOPE

The Contractor shall deliver a quantity of one (1) dilution refrigerator system that meets all requirements listed below, inclusive of FOB Destination delivery, installation, warranty and training, and option line items.

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 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.
