Development of a Tape Winding Mechanism for HTS Power Cables

New Generation of DC Power Transmission Technology Using HTS Cables

High Tc superconducting (HTS) cables and their application to develop a DC power transmission system with substantial advantages have been studied. Technical analysis of the HTS DC electrical power transmission system behaviours have been carried out with the HTS DC cable technology employed and the system models built.

Investigations of HTS Twisted Stacked-Tape Conductor

A new method of fabricating HTS tape coil

High-Temperature Superconducting (HTS) materials can introduce substantial improvement in signal-to-noise ratio (SNR) of images for small-size sample or low-field MRI system (<1T) [1]. Expensive HTS thin film is typically used for making receiver surface coils for substantial SNR improvements [2]. A 5-inch HTS tape coil using silver-alloy sheathed Bi-2223 tape was first developed [3], which all...

Industrial Cu-Ni alloys for HTS coated conductor tape

Copper rich Cu-Ni alloys have been textured with the RABiTS method in order to get non-magnetic and cost efficient substrates for coated conductor wires. The study is focused on two industrial compositions: Cu55Ni45 (Constantan) and Cu70Ni30. Studies on surface roughness have been done. The effects of annealing conditions (temperature and atmosphere) on the grain boundaries deepness were analyz...

HTS tape RF coil for low field MRI

M. C. Cheng, K. H. Lee, K. C. Chan, K. K. Wong, E. S. Yang HKU Jockey Club MRI Engineering Center, Hong Kong, Hong Kong, China, People's Republic of Abstract A 5-inch RF receiving coil for 0.21T MRI system was developed using multifilament Bi-2223 High Temperature Superconducting (HTS) tape. The coil was designed to enclose the imaging sample so as to enhance the filling factor and field-of-vie...
