Investigations of HTS Twisted Stacked-Tape Conductor

Nonlinear Model of Tape Wound Core Transformers

Recently, tape wound cores due to their excellent magnetic properties, are widely used in different types of transformers. Performance prediction of these transformers needs an accurate model with ability to determine flux distribution within the core and magnetic loss. Spiral structure of tape wound cores affects the flux distribution and always cause complication of analysis. In this paper, a...

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...

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...

Normal domain temperature profile in second generation HTS tape wire

BACKGROUND Studies of the normal zone in high-temperature superconducting wires are extremely important for power applications, such as fault current limiters, motors, cables etc. We studied the temperature distribution and normal domain propagation in high-temperature superconducting YBCO tape with highly resistive substrate. FINDINGS For applied voltages exceeding a certain threshold value ...
