This paper explains novel methods of the excessive current protection for a single unit 25-kA current injection system (CIS) with no test interruption. The principle object of this paper is to provide a fast detection of excessive current in the system by means of an unbalanced magnetic flux current limiting device (CLD) for the predetermined current tests. The proposed techniques will be used to ... View full abstract»

A versatile experimental facility was designed and set up to measure transport ac losses, magnetization ac losses, and total ac losses in high-temperature superconductors at variable temperatures. Several sets of measurements were carried out in the temperature range of 35 K to 100 K. Sample temperature during the measurements could be controlled within plusmn0.5 K of set temperature. Temperature ... View full abstract»

A globally optimum minimum stored energy optimization strategy is implemented to design actively shielded superconducting magnet configurations used in high-field applications. The current density map is first obtained and used as a foundation for the magnet configurations by placing coils at current density local extremities. Optimized current density maps based on the stored energy formulation a... View full abstract»

A terahertz modulator based on the Type-II superconductor flux flow oscillator has been proposed. Analytical calculations are presented and the effects of intrinsic and extrinsic parameters such as disorder strength of crystal, penetration depth, frequency, and amplitude of the modulated current on the radiation power spectrum have been studied. The proposed structure also exhibits a mixer-like be... View full abstract»

| | PDF (1156 KB) | HTML

Many alternative energy power generation systems create DC electricity. Also, many devices consume DC converted from AC. Therefore, it may be possible to reduce conversion losses and CO<sub>2</sub> emissions by adopting DC distribution. We assume that superconducting cables will be used for dc distribution because their electrical resistance is almost zero. However, if a superconductin... View full abstract»

The voltage and temperature of YBa2Cu3Ox (YBCO) tapes with different structures were measured at alternating-current overcurrent conditions in liquid nitrogen. A safety temperature limit of the tapes with different structure was obtained based on the measured critical-current degradation data of the YBCO tapes. According to heat conduction model, the electrical and thermal pe... View full abstract»

In dc and ac practical applications of MgB2superconducting wires, an important role is represented by the material sheath that has to provide, among other things, a suitable electrical and thermal stabilization. One way to obtain a large-enough amount of low-resistivity material into the conductor architecture is to use it as the external sheath. In this paper, we studyexsitu<... View full abstract»

This paper presents a mechanical tuning method for tuning the center frequency of a narrowband high-temperature superconducting filter. The filter is designed with 0.5-MHz bandwidth at 166.9 MHz and is fabricated. Tuning is carried out based on the time-domain response of filter return loss. The filter can be precisely tuned to a desired center frequency while maintaining a high-frequency performa... View full abstract»
