About this file
This document is a Request for Information (RFI) issued by the Naval Surface Warfare Center Philadelphia Division (NSWCPD) regarding the feasibility of manufacturing a high temperature superconducting (HTS) coil system with specific performance parameters.
The key details are as follows: The Navy is seeking information on manufacturing an HTS coil system with parameters such as dipole, sine wave frequency, operating temperature, output duration, coil dimensions, and power requirements. The coil system must meet certain constraints, including a threshold shipping volume based on a flatbed truck and an objective shipping volume based on an ISO container. The cryogenic system must use a closed-loop design and minimize the use of magnetically susceptible materials. The Navy is requesting responses that address challenges with HTS component raw materials, lead times, anticipated heat loads and cryogenic system requirements, driving voltage needs, and overall power demands for the coil, current injection, and cryogenic subsystems. Respondents are required to provide company information, prior relevant experience, and technical details within the specified parameters. Responses are due by June 20, 2024 and should be submitted via email.

Additionally, the following constraints/details should be considered in addressing the feasibility to manufacture a coil system:
· A Threshold shipping volume based on the footprint of a flatbed truck, 20x8x8 ft Objective shipping volume is based on interior dimensions of an all-access ISO container, 18x5.75x5.75 ft
· The Power factor from the source will be greater than .9
· The cryogenics system:
· may use gaseous cryogens, provided it is a closed loop system.
· may not permit new cryogen to be added once cool down commences (i.e. closed-loop cooling)
· shall minimize the use of magnetically susceptible materials in the magnet design (i.e. Coil support structure, cryostat, etc.)
· shall be operational in its self-produced magnetic field
· shall not permit cryogen bath solutions
