The development of coils which can survive a quench is a crucial aspect for demonstrating the viability of MgB2-based main magnet coils for MRI. Here we have studied the thermal stability properties of a large (outer diameter: 901 mm; winding pack: 44 mm thick × 50.6 mm high) conduction-cooled, R&W, MgB2 superconducting coil. Minimum quench energy (MQE) values were measured for different coil...
This paper summarizes the latest developments in some on-going research at the Wentworth Institute of Technology to qualify a new reinforced-2212 superconductor, being developed by Solid Materials Solutions in Chelmsford, MA, for use in high magnetic fields. Under an NIH-funded grant, we are developing a high-speed spin test which will impose circumferential hoop stresses on the 2212 windings...
A material microstructure in-situ analysis instrument was designed in which a scanning electron microscope and a small refrigerator were used to observe the microscopic morphology and cool the sample (can be cooled as low as 15 K), respectively. The instrument is also equipped with a deformation excitation device that can stretch and compress the material in situ. The vibration damping...
Epoxy/aluminum nitride composites (EP/AlN) with high thermal conductivity, low thermal expansion and excellent insulation characteristics are particularly suitable for protecting a superconducting power equipment from the permanent damage of temperature rise and internal stress in quenching process. In this work, micro/nano AlN particles were used as fillers to improve the thermal conductivity...
Recent results are reported in the development of 2-layer cable-in-conduit (CIC) that is designed for hybrid-coil magnets. The CIC preserves the full performance of the individual wires, and can be formed into flared-end windings for dipoles into layer-wound toroids and solenoids for hybrid windings for tokamaks. The structure of the CIC windings is designed to accommodate winding and...
We have magnetically modelled a fast switching, polarizing, superconducting undulator. The particular design is called the SuperConducting Arbitrarily Po-larizing Emitter, or SCAPE, It has a four jaw design, and produces LCP, RCP, L-H and L-V polarization states. This design uses a dual SC undulator scheme to achieve fast switching. Each undulator is preset to generate a fixed polarization...
Superconducting magnets are one of the superior contenders in achieving the targets of electric aircraft industry successfully as they have very high power densities compared to other battery storage systems. Many aviation research agencies are looking at superconducting magnets as one of the alternate in replacing the conventional jet engines completely (electric aircrafts) or partially...
