Superconducting conductors and coils are critical components in high-field applications, requiring rigorous performance evaluation to ensure reliability and efficiency. This paper introduces the design and construction of a superconducting conductor testing apparatus, developed to assess the performance of superconducting conductors and coils under high magnetic fields. The apparatus consists...
Thea Energy has created the “Canis” 3x3 array of high-temperature superconducting (HTS) planar coil magnets as a prototype for the “Eos” stellarator. This poster covers instrumentation of the Canis 3x3 magnet array highlighting the magnetic field control and field validation support systems. Field sensors mounted on each coil combined with individual magnet power supplies allowed the array...
In superconducting applications such as NMR/MRI, SMES, and fusion reactor systems, the critical current (Ic) of the wire is an essential component in determining device performance. This critical current depends on the applied magnetic field (B) and temperature (T), and particularly exhibits magnetic anisotropy in tape-shaped HTS. SuNAM, a manufacturer of HTS wire, operates a 4 Tesla Ic(B, T)...
The accurate measurement of thickness profile across the width of REBCO conductors is critical to design and fabrication of REBCO magnet windings. This is because the non-uniform thickness profile such as so-called ‘dog-bone’ or ‘pillow’ shapes compromise winding’s geometrical integrity, which is especially critical for dry-wound pancake coils. Non-uniform also has significant impact on the...
In view of the challenges such as small range, low accuracy and weak tracking ability in current measurement of high-temperature superconducting cable for ultra-high field magnets, a high precision and fast response current measurement scheme based on core coil improvement and superconducting coil compensation is proposed. A DCCT high-temperature superconducting compensation coil has been...
Currently, The National High Magnetic Field Laboratory (NHMFL) is in the process of developing a 40 T High Temperature Superconducting (HTS) user magnet, and for the magnet development, it is essential to evaluate the performance of a large number of HTS modules in the future. Typically, each HTS module requires performance evaluation after winding and before being assembled into a magnet....
High-temperature superconducting (HTS) motors have emerged as a compelling alternative to conventional copper-based systems by achieving significantly higher current density and stronger magnetic fields, thereby realizing remarkable increases in torque density. These advantages have spurred intensive research into adopting HTS motors for electric propulsion in aircraft and ships. While...
A concept for a magnetic annealing oven for applications in the fabrication of MRAM and other GMR, TMR effect devices is investigated. With the oven, it is possible to anneal 20 to 50 wafers with a diameter of 200-300 mm at temperatures up to 450°C in a magnetic field of 1 T or more. The magnetic field in this study is created by HTS coils made up of THEVA, SuperOx, Sumitomo and Shanghai...
