Overview	High Temp Superconducting (Hts) Coils Description Request for Information Naval Surface Warfare Center Philadelphia Division (NSWCPD) is the Navy-s experts in the development, performance, and characterization of high temperature superconducting (HTS) coils and related technology. Recently, NSWCPD has begun exploring potential applications utilizing alternating current (AC) vice the direct current (DC) operations that have been previously explored. When AC is introduced two issues arise. Under AC operating conditions the superconductor begins to generate heat that adds to the burden on the cryogenic system. The exact amount of heat is dependent on the frequency, current, and coil geometry and may not be simple to calculate. This makes designing the cryogenic package challenging. As frequency increases for some constant current, so too does the voltage required to drive the signal, despite not increasing its amplitude. This quickly can become taxing on the current injection system.These problems are exacerbated by the frequencies the Navy is interested in, which is several hundred Hz to single digit kHz. There is minimal information describing superconducting coils being operated in this frequency band. The Navy is requesting information on the feasibility to manufacture a coil system using the following parameters listed in ATTACHMENT 01. 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 ftObjective 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 ...
